1.9

UnoCore

• Marked the following methods as obsolete. To get the old behavior, use Uno.Math.Floor(x + 0.5f) instead.
  • Uno.Math.Round(float)
  • Uno.Math.Round(float2)
  • Uno.Math.Round(float3)
  • Uno.Math.Round(float4)

  • Uno.Math.Round(float, int)
  • Uno.Math.Round(float2, int)
  • Uno.Math.Round(float3, int)
  • Uno.Math.Round(float4, int)
• Math.Round(double, int) now throws ArgumentOutOfRangeException if digits are less than zero or larger than 15. This matches .NET behavior.
• Fixed a bug where Math.Round(double, int) with large, finite inputs would produce infinities.
• Math.Abs(int.MinValue) now throws OverflowException. This matches .NET behavior.
• Added overloads of Math.Abs, matching .NET:
  • Math.Abs(sbyte)
  • Math.Abs(short)
  • Math.Abs(long)
• Removed long obsolete importers:
  • ArrayImporter
  • BufferImporter
  • FontFaceImporter
  • SpriteFontImporter
  • IndexBufferImporter
  • Texture2DFileImporter
  • Texture2DImporter
  • TextureCubeFileImporter
  • TextureCubeImporter
  • VertexBufferImporter
• Marked the following methods as obsolete. Those pulled in a big dependency that is currently unused.
  • Uno.Graphics.Texture2D.Load(BundleFile)
  • Uno.Graphics.Texture2D.Load(string)
  • Uno.Graphics.Texture2D.Load(string, byte[])

.NET

• Fixed a code-generator bug where unsigned modulo got treated like signed modulo, causing negative values in the result.
• Fixed a code-generator bug where ulong values larger than long.MaxValue didn't get sign-extended correctly.
• Fixed a code-generator bug where signed division was used instead of unsigned division, leading to incorrect results for big dividends.

Uno Compiler

• The following unsafe implicit casts has been turned to explicit casts. This matches C# behavior, and should avoid unexpected overflows:
  • sbyte -> ushort
  • sbyte -> uint
  • sbyte -> ulong
  • short -> uint
  • short -> ulong
  • int -> ulong
• We no longer sign the .NET assemblies in Uno.
• uno disasm has been removed on macOS, as it's has been broken for a while and there's essentially no users.

1.8

Uno compiler

• Exposing internal types through protected members is now a compilation error, to match C#'s behavior. Some code may need to be updated, for instance by making the exposed type public or the member internal.
• Fixed a bug that resulted in a crash at startup during the construction of Uno's runtime type information when using certain (rare) combinations of generic types.

UX Compiler

• Fixed a codegen bug where property bindings to properties with generic type arguments (such as LetFloat) would generate invalid Uno code.

Uno.Net.Http

• Made the following types internal. They were never meant to be exposed in the first place, and shouldn't be used:
  • Uno.Net.Http.AbsolutePathParser
  • Uno.Net.Http.HashParser
  • Uno.Net.Http.HostInfo
  • Uno.Net.Http.HostInfoParser
  • Uno.Net.Http.QueryParser
  • Uno.Net.Http.SchemeParserResult
  • Uno.Net.Http.SchemeParserResult
  • Uno.Net.Http.UserInfoParser
  • Uno.Net.Http.UriScheme
  • Uno.Net.Http.UriSchemeType
• Introduced Uri.Fragment.
• Marked Uri.Hash as obsolete. Use Uri.Fragment instead.
• Marked Uri.GetQueryParameters() as obsolete. Use Query.Substring(1).Split('&') instead.
• Marked Uri.Combine(string, string) as obsolete. Use String.Format("{0}/{1}, baseUri.TrimEnd(new char[] { '/' }, uri.TrimStart(new char[] { '/' }))" instead.
• Marked Uri.Combine(string, string) as obsolete. Use Uri(Uri, string).OriginalString instead.
• Marked Uri.Encode as obsolete. Use Uri.EscapeDataString(string) instead.
• Marked Uri.Decode as obsolete. Use Uri.UnescapeDataString(string) instead.

Uno.Threading

• Marked public versions of ConcurrentDictionary.Add(TKey, TValue) and ConcurrentDictionary.Remove(TKey) as obsolete. Use IDictionary-versions instead.
• Marked public versions of ConcurrentDictionary.GetEnumerator() as obsolete. Use IEnumerable-versions instead.
• Marked public versions of ConcurrentDictionary.Keys and ConcurrentDictionary.Values as obsolete. Use IDictionary-versions instead.

UnoCore

• Removed obosolete methods from Uno.Color. These has been obsolete since Uno 0.46:
  • Uno.Color.ToRgb24(float3)
  • Uno.Color.ToRgba32(float4)
  • Uno.Color.FromRgb24(int3)
  • Uno.Color.FromRgb24(uint)
  • Uno.Color.FromRgba32(int4)
  • Uno.Color.FromRgba32(uint)
  • Uno.Color.ToHex(int3)
  • Uno.Color.ToHex(int4)

.NET

• Fixed a code-generator bug where long-literals that were larger than int.MaxValue, but smaller than uint.MaxValue accidentally got sign-extended.
• Fixed a code-generator bug where shifts on unsigned values accidentally got sign-extended.

1.7.1

UnoCore

• Fixed a bug in IntPtr.GetHashCode where the returned hash-code was more or less random. This lead especially to big problems when using IntPtr as a Dictionary key.

1.7

UnoCore

• Removed obsolete method BitmapFont.CreateFromPbf().
• Removed obsolete classes SdfFontImporter, SdfFontShaderBlock and SdfFontShader.
• Made String.IndexOf() and String.LastIndexOf() throw ArgumentOutOfRangeException on negative values on all build-targets.
• Implemented String.IndexOf(char, int, int), String.LastIndexOf(char, int, int), String.IndexOfAny() and String.LastIndexOfAny.
• Implemented Array.IndexOf<T>() and Array.LastIndexOf<T>().
• Removed everything in Uno.Content.Splines and Uno.Content.Models. This was already marked as obsolete a while ago, and all known users of the API has been removed.
• Random.NextInt(int) now throws ArgumentOutOfRangeException when passed negative values, and returns zero when passed zero.
• Random API has been more aligned with the .NET API:
  • The SetSeed-method has been marked as obsolete. Construct a new Random object instead to change the seed.
  • The NextInt-methods has been renamed to Next. The old methods are still available, but will produce obsolete warnings when used.
  • A NextDouble has been added, that returns a number between 0.0 and 1.0.
  • The NextFloat-methods has been marked as obsolete. Use the NextDouble method instead.
  • The NextFloat2, NextFloat3 and NextFloat4-methods has been marked as obsolete. Use multiple calls to NextDouble instead.

1.6.1

UX Compiler

• Fixed a bug introduced in 1.6 that caused E0000: The given key was not present in the dictionary. errors to be generated for some UX document roots.

1.6

Long path? Long code.

We can now extract zip files containing long filenames (255+ characters) on Windows. This enables things like providing Node.js on-demand, requiring long filenames to work.

Environment variables

The following environment variables can be used to configure Uno globally, potentially useful in CI environments:

• LOG_LEVEL=<0..3> - Set verbosity level (default = 0)
• LOG_TRACE=1 - Print exception stack traces where available
• DEBUG_GL=1 - Enable the OpenGL debug layer in .NET builds

Android build target

• Added the following build properties for requiring gradle repositories via UXL:
  • Gradle.BuildScript.Repository
  • Gradle.AllProjects.Repository

Project files

• Support for iPhone 20pt 2x and 3x icons has been added. This can be customized using the iOS.Icons.iPhone_20_2x and iOS.Icons.iPhone_20_3x project-setting, respectively.
• Support for iPad 20pt 1x and 2x icons has been added. This can be customized using the iOS.Icons.iPad_20_1x and iOS.Icons.iPad_20_2x project-setting, respectively.
• Support for iPad Pro icons has been added. This can be customized using the iOS.Icons.iPad_83.5_2x project-setting.
• Support for iOS Marketing icons has been added. This can be customized using the iOS.Icons.iOS-Marketing_1024_1x project-setting.
• Support for iPhoneX Launch Image has been added. This can be customized using the iOS.LaunchImages.iPhone_Portrait_iPhoneX_3x and iOS.LaunchImages.iPhone_Landscape_iPhoneX_3x project-setting.

Command-line interface

• The following old commands were removed from the release: cp, disasm, mkdir.

.NET backend

• We now build 64-bit code by default when the OS is 64-bit on all platforms. You can pass -DX86 or -DX64 to uno build to override the architecture.
• UXL: <Require UnmanagedLibrary[.{x86,x64}]> was added to handle native DLL dependencies for P/Invoke. We can now make sure the DLL is copied to the right directory without making assumptions about where it should go.
• Set DEBUG_GL=1 in your environment to enable the OpenGL debug layer at run-time. This is available in .NET builds on macOS and Windows.

MSVC build target deprecated

• The 'native' target now serves the same purpose, and works on both macOS and Windows.
• We now build 64-bit code by default when the OS is 64-bit on all platforms. You can pass -DX86 or -DX64 to uno build to override the architecture.
• UXL: <Require SharedLibrary[.{x86,x64}]> was added to handle DLL dependencies on Windows. We can now make sure the DLL is copied to the right directory without making assumptions about where it should go.

Environment.NewLine

• We've introduced Uno.Environment.NewLine as an alias for "\r\n" on Windows and "\n" on macOS, iOS, and Android.
• Uno.IO.TextWriter and Uno.Text.StringBuilder has been updated to respect Uno.Environment.NewLine.

C++ backend

• (Breaking) We're now using char16_t as the underlying type for Uno.Char. Previously we were using wchar_t on WIN32 and int16_t on other platforms, so call-sites marshaling strings between Uno and native APIs need to make sure they're using the correct pointer types for the native API.
• We're now using int32_t as the underlying type for Uno.Int.

UnoCore

• Added Parse(string) and TryParse(string, out float4) to Color.
• Marked Color.FromHex(string) as obsolete. Use Color.Parse(string) instead.
• Uno.Buffer does no longer support "read-only" buffers.
• Deprecated methods taking Uno.Buffer in OpenGL and Uno.Graphics namespaces - use the byte[] overloads instead.
• Now using type-safe GL handle types on .NET, previously we were passing ints.
• The following types in the Uno.Native.Textures namespace (.NET utils for native font & texture loading) were moved from fuselibs:
  • Uno.Native.Fonts.FontFace
  • Uno.Native.Fonts.RenderedGlyph
  • Uno.Native.Fonts.FontRenderMode
  • Uno.Native.Textures.TextureFileFormat
  • Uno.Native.Textures.TextureType
  • Uno.Native.Textures.PixelFormat
  • Uno.Native.Textures.Texture
• The following importer APIs still exist, but will no longer work (deprecated since before 1.0):
  • Uno.Content.Fonts.SdfFontImporter
  • Uno.Content.Fonts.SpriteFontImporter
  • Uno.Content.Models.ModelBlockFactory
  • Uno.Content.Models.ModelImporter
  • Uno.Content.Models.ModelFileImporter

Node.js support

In this release we give Uno projects two new features:

• NPM support: When a package.json is found in the same directory as the .unoproj, we automatically run npm install.
• FuseJS (ES2015) support: JavaScript files added as filename.js:FuseJS in a .unoproj are automatically transpiled to ES5 before bundled into the app.

To support this we need to find node and npm. If the commands aren't in your PATH, their locations can be provided like this in ~/.unoconfig (%USERPROFILE%\.unoconfig):

Tools.Node: "%PROGRAMFILES%\\nodejs\\node.exe"
Tools.NPM: "%PROGRAMFILES%\\nodejs\\npm.cmd"

1.4

C++ backend

• The following unused entities were removed from Uno/Memory.h:
  • uGarbageCollect()
• The following unused entities were removed from Uno/ObjectModel.h:
  • uArray::Copy()

UnoCore

• Added NewGuid() & ToByteArray() to Guid.

Gradle

• Added support for customizing settings.gradle by using [Require Gradle.Settings="include ':something'"].

Uno compiler

• We now check that finally clauses don't contain illegal control flow. break, continue and return are not allowed in finally clauses.

AppDelegate

• Fixed regression on iOS where, because we had implemented the methods for pushnotifications apps were rejected from the app store for not requiring notifications even if they didnt use the notification's feature

1.3

Project format

• Fixed a bug where the Name property in .unoproj wasn't honored. By default, Name is derived from the project filename if not set explicitly, and by accident we were using the default value instead of the user-provided value, leading to inconsistencies. If you have provided Name explicitly, we will now use that name when producing output files, i.e. UserProvidedName.apk (Android) and UserProvidedName.exe (.NET) instead of DefaultName.apk and DefaultName.exe.

C++ backend

• Don't lazy initialize types without a user-defined static constructor. This removes a bunch of Foo_typeof()->Init() calls from generated code, for instance when accessing a static field, to reduce run-time overhead.

Deprecated importers

• import BundleFile(FILENAME) and remaining parts of the importer system in Uno.Compiler.ImportServices has been deprecated. We can now pass the filename directly to the operator instead: import(FILENAME). The import operator returns a BundleFile object. The classes texture2D and textureCube contains Load() methods accepting BundleFile which can be used to import texture files, replacing the deprecated texture importers.

  Old syntax	New syntax
  import BundleFile(FILENAME)	import(FILENAME)
  import Texture2D(FILENAME)	texture2D.Load(import(FILENAME))
  import TextureCube(FILENAME)	textureCube.Load(import(FILENAME))

Removed UXL variable 'Mono'

• The UXL variable 'Mono' was removed, since the need of it was removed.

Improvements to Android builds

• Strip SO files in release builds. This can massively reduce the size of the shipping app.
• Use gradle to generate required .iml files. This should make us more flexible both to changes from Fuse & to changes from Google in Android Studio. There is now only 1 .iml generated and that is in the app sub-directory of the project and only for builds with the -d flag.

Resource Crunching

• Disabled android's resource crunching. Android will no longer convert pngs to WebP or otherwise modify your images to save space. See the following for details https://developer.android.com/studio/build/optimize-your-build.html#disable_crunching

.NET backend

• Validation of method signatures and data types when linking external assemblies has been improved. This revealed a few minor problems in UnoCore that has been fixed:
  • Uno.Net.EndPoint: Constructor is now internal because a compatible constructor doesn't exist in .NET.
  • Uno.Threading.Monitor.TryEnter(): Return type is now bool to match .NET.
  • Uno.Text.StringBuilder: This class now maps to System.Text.StringBuilder on .NET.
  • Uno.Tuple<...>: The AppendItems(StringBuilder sb) methods are no longer public because compatible methods don't exist in .NET.
• Introduced Uno.Compiler.ExportTargetInterop.DotNetOverrideAttribute. This attribute is used to override implementations of static methods in types that are mapped to .NET, so that the Uno implementation is used instead of the existing .NET implementation. We use this on string.Format() because Uno only implements a subset of the functionality.

Uno.DateTime changes (breaking!)

• Uno.DateTime was changed from being a class to a struct, to make it .NET-compatible
• The UtcNow property has changed types from being Uno.Time.ZonedDateTime to being Uno.DateTime, to make it .NET compatible
• The Now property has been made internal until better .NET-compatible support can be provided

Uno compiler

• The compiler has become stricter about accessing entities from other packages. Previously it was in some cases possible to access internal entities from a different package without getting a build error.
• The compiler now accepts empty structs. It's no longer necessary to add a dummy field to work around build errors when forward declaring .NET structs for instance.

1.2

Broken tools removed

• uno perf-test and uno perf-cmp were unused and broken, and have been removed.

Deprecations

• The unused class Uno.FakeTime has been marked as obsolete.
• The ExportCondition attribute in Uno.Compiler.ExportTargetInterop has been marked as obsolete.
• The legacy Alert and Confirm methods in Uno.Diagnostics.Debug has been marked as obsolete.
• The redundant SupportsMipmap fields in Uno.Graphics has been marked as obsolete.
• The constant float.ZeroTolerance has been marked as obsolete.

1.1

Uno.Data.Json

• Fixed a bug where a JSON object with the same key repeated would cause a crash.

UX Compiler/Fuse Preview Optimizations

• Many optimizations to the UX compiler to reduce compile times and editing speed in Fuse Preview.

Android

• Android's allowBackup option is now configurable via the optional Android.AllowBackup value in the unoproj file

Uno.Testing

• A bunch of internal details that were never intended to be public has been marked as internal:
  • AbstractRunner
  • DebugLogMessageDispatcher
  • AssertionFailedException
  • HttpMessageDispatcher
  • NamedTestMethod
  • Registry.Add()
  • Registry.Count
  • NamedTestMethod Registry[int index]
• Registry.FindTest() has been removed.
• TestSetup.Runner has been marked as readonly.
• Assert.Ignore() has been added to allow ignoring tests at run-time.
• A bug in Assert.AreNotEqual(float, float) and Assert.AreNotEqual(double, double) has been fixed, to make them format the result strings similar to their Assert.AreEqual counter-parts.
• TestAttribute and IgnoreAttribute have gotten the apropriate AttributeUsages to match their behaviour. This means that using them outside of methods will now give compile-errors instead of doing nothing.

1.0

ux:Ref fix for MaterialDesign community package

• Fixed a bug where nodes marked ux:Ref would not generate correct code. This fixes Duckers/Fuse.MaterialDesign#11.

Add ux:Test support in UX compiler

• The UX compiler now supports ux:Test, which is similar to ux:Class but generates a bootstrapped test class which can be run with uno test. See docs for details.

Add 'uno sdkmanager'

• This lets you use Android's new CLI sdkmanager. The old uno android approach is deprecated.

New UX Markup features

• Introduced <ux:Resources> tag which can be used as the root tag in UX files that contain only ux:Class'es and ux:Global's. This avoids having to use a "dummy panel" to encapsulate such resources.

iOS Screen Rotation

• Fixed a bug that broke layout when rotating the screen on iOS

0.47

iOS Backend

• Fixed a problem that resulted in "FATAL ERROR: value cannot be null" when building for iOS without having set a development team manually.

.NET backend

• Worked around an issue that resulted in errors like ERROR: Failed to compile .NET type 'XXX': The invoked member is not supported before the type is created. when using certain class attributes when compiling for .NET (e.g. local preview)

Uno.Net.Sockets

The following methods that were marked as obsolete in Fuse 0.33 have now been removed:

• Socket.Send(byte[], int, int)
• Socket.Receive(byte[], int, int)

All Android builds now use Gradle & CMake

Back in 2013 Google announce they would be changing their supported build system to Gradle and that Ant would be deprecated. Since then Gradle and android have grown to the point where Gradle is now 'the way' to build and manage your dependencies for Android projects. The road for native development has been much rockier especially if, like us, you interact with Android from an external tool.

However we are finally in the position where we are happy enough with stability and compatibility that we are going to remove the deprecated Ant build system and switch to Gradle for all builds. We have been offering Gradle builds from Fuse using a build flag for a long time and the input from users has been invaluable.

What this means for you is as follows:

• You no longer have to use the -DGradle flag when building for Gradle support
• You will be able to use a simple Uno attribute to install any of the mountain of libraries available for the android platform via Maven & JCenter
• The projects we generate should be compatible with Android Studio[0]. Build with -d to open the project in AS.

This does however have an effect on what themes are available for Native widgets. The reason for this is that more and more 3rd party android libraries (such as Facebook's login UI) are using UI elements (or other features) not available on older android versions. To keep to our high standard of device & version compatibility this required us to switch from using com.android.Activity to android.support.v7.app.AppCompatActivity. This provided compatibility versions of the APIs needed but means that the supported Android native themes must inherit from AppCompat.Theme

That means that the Holo will no longer work with Fuse apps although Theme.AppCompat, Theme.AppCompat.Light, etc will.

As always please reach out to us if you hit any issues.

[0] We aren't providing support for this workflow as changes to Android Studio are out of our control.

Android Studio Details

• We no longer generate the .iml files & instead let Android Studio do this.

iOS Launch Options

• You can now access the latest launch options in iOS apps as a ObjC.Object from the Uno.Platform.iOS.Application.LaunchOptions property.

0.46

Foreign Objective-C

• Uno has now enabled automatic reference-counting (ARC) in Foreign Objective-C code. If you have foreign code and Xcode complains about methods like dealloc, retain, release, or autorelease being unavailable, this can be fixed by removing the calls to those methods.

Uno.Color

• Color.ToRgb24, Color.ToRgba32, Color.FromRgb24, Color.FromRgb24, Color.FromRgba32 and Color.Rgba32FromHex, Color.ToHex(int3) and Color.ToHex(int4) have been marked as obsolete. See the obosletion-warnings for replacements.
• Color.FromHex no longer accepts sign-characters in the hex-string. This wasn't intended to work in the first place, and only worked in some bizarre corner-cases.
• Color.FromArgb and Color.ToArgb has been added.

Switch from gradle-experimental to standard Gradle

• Using the -DGRADLE flag will now use the standard Gradle and CMake to build your projects.
• Gradle will become the default build system in the next release and Ant support will be removed.

0.45

Android.Theme

The native Android-theme used by an app has been made configurable, by adjusting the Android.Theme-property in the project-file. At the same time, we've changed the default theme from "Holo" to "Material".

To get the old behavior, add this snippet to your project file:

"Android": { "Theme" : "Holo" }

0.44

Xcode project generation

• Added $(inherited) to the framework search paths, which is sometimes necessary when using CocoaPods.

Uno.Threading

As mentioned in the changelog for Fuse 0.32, the following obsolete methods have been removed:

• AutoResetEvent.Create()
• ManualResetEvent.Create()
• Mutex.Create()
• Mutex.Lock()
• Mutex.TryLock()
• Mutex.Unlock()
• Semaphore.Create()
• Thread.Create()
• Thread.Join(int)

If you still haven't updated your code to to match, you'll now get build-errors. See the changelog for Fuse 0.32 for upgrade instructions.

In addition, EventWaitHandle has been added as a base-class for AutoResetEvent and ManualResetEvent, and ConcurrentCueue no longer implements IDisposable, both similar to what .NET does.

Uno.Net.Sockets

• Socket.Send(byte[], int, int) has been marked as obsolete. It doesn't exist (nor work) on .NET-targets. Use Socket.Send(byte[], int, int, SocketFlags) instead.
• Socket.Receive(byte[], int, int) has been marked as obsolete. It doesn't exist (nor work) on .NET-targets. Use Socket.Receive(byte[], int, int, SocketFlags) instead.

Uno Refactor

A large amount of refactoring has been undertaken to solve two issue:

• Enabling testing without GL
• Moving the root-view code to fuselibs

This series of changes are seen as steps to enable where we want to go, we understand that things can feel a bit in-cohesive at this stage. But with these changes landed we will be able to iterate on the code bases more easily and fix some long standing issues (especially in areas such as system ui & fullscreen)

• The new CoreApp class has been created. This is the new root application class instead of Uno.Application. It contains the lifecycle, Current & Load.

• All platforms now feed lifecycle events through Platform.CoreApp

• Uno.Application inherits from this and on desktop adds the GraphicsController and Window. Much of the Application class is deprecated for mobile targets. Window is still present for mobile but is deprecated for imminent removal.

• GraphicsController is a class which holds much of the code that used to belong to GraphicsContext. It is only used on desktop. The reason for the change is that for mobile, everything in managed in fuselibs. GraphicsContext now exists as a handle.

• A class called Displays had been added which contains a list of Displays. For now the most used field is MainDisplay, which for all current platforms is the only Display

• A Display class now exists which holds the Density property & Tick event. There are subclasses of this iOS, Android & Desktop that handle the plumbing.

• A class called OSFrame has been added which is the new base class of Window. As mentioned above, Window continues to be used on desktop & is deprecated on mobile.

• Window contained far too many of the events. The EventSources namespace the new home for these migrated events. There are separate static classes for InterApp, HardwareKeys, Text & Mouse events. This separation will allow us to re-evaluate them separately and work on their future place in the API.

• The mobile root-view bootstrapping is removed from Uno and moved to Fuselibs

• SystemUI and it's bootstrapping is removed from Uno and moved to Fuselibs

• Key events now have an Origin field, which is the OSFrame they originated from. This is for platforms where these events originate from Windows as opposed to UI elements

• All core libraries that touched Platform2 events have been updated to use Platform rather than Platform2

• Events which on some platforms are forbidden (like quit) now live in an class called Unsafe

0.43

Xcode project generation

• Xcode.ShellScripts are now escaped as string literals.

Android builds

• Added a JNI.SystemLibrary UXL element for linking in libraries like liblog.
• Gradle builds now depend on v23.4.0 of support-v4, appcompat & design. Rather than using wildcard for the version.

Foreign Code Improvements

• You can now make Uno properties where the bodies of the getter and setter are foreign code. For example:

    [Foreign(Language.Java)]
    public int Foo
    {
        get
        @{
            return getSomeSubsystem().refreshRate;
        @}
        set
        @{
            getSomeSubsystem().refreshRate = value;
        @}
    }
  

  On foreign Java methods you can also provide annotations.

    [ForeignAnnotation(Language.Java, "TargetApi(19)")]
    public void Foo()
    @{
        ...
    @}
  

  Note that you do not specify the leading @ symbol. This is added by Uno.

• Fixed a bug where the argument names to foreign methods would be renamed because of other conflicting names in the same scope.

• @{TypeName} macros now expand correctly in foreign Java & ObjC code.

• The Uno.Compiler.ExportTargetInterop.Foreign.ObjC.Object class has now been removed. Use ObjC.Object instead.

Uno.Threading

To align better with the .NET APIs and to reduce some performance issues with our low-level threading API, we have revamped our API a bit. The following changes are noteworthy:

• Thread.Join(int) has been marked as obsolete. It's not implemented on most platforms, so it's not very useful in its current form.
• Thread.Create(), Mutex.Create(), Semaphore.Create(), AutoResetEvent.Create() and ManualResetEvent.Create() has been marked as obsolete. Use the constructors for the respective classes instead.
• Mutex.Lock() and Mutex.TryLock() has been marked as obsolete. Use Mutex.WaitOne() instead.
• Mutex.Unlock() has been marked as obsolete. Use Mutex.ReleaseMutex() instead.
• Thread, Mutex, Semaphore, AutoResetEvent and ManualResetEvent are now sealed, and cannot be inherited from.

In order to get a smooth transition, the deprecated APIs are still present in the current release (but should produce compiler-warnings when used). They will however be removed soon.

0.42

Legacy Android Bindings Removed

As planned Legacy bindings are removed this release. Foreign Code is now the only official way of interfacing with native code.

Various changes

• Makes uno build native work on Windows (eventually to replace uno build msvc)
• Removes outdated Android solution for VS2015
• Some other commits that should be harmless
• Android NDK has renamed ndk-stack.exe to ndk-stack.cmd, we can now use either of those

0.41

Deprecation of build targets

The following build targets will generate a warning if used:

uno build webgl
uno build ffos

We're deprecating build targets based on JavaScript because our JavaScript backend is no longer maintained.

Deprecation of importers

The following will now generate a warning if compiled:

import Uno.Array<T>()
import Uno.Buffer()
import Uno.Content.Fonts.FontFace()
import Uno.Content.Fonts.SfdFont()
import Uno.Content.Fonts.SpriteFont()
import Uno.Content.Models.Model()
apply Uno.Content.Models.Model()
import Uno.Graphics.IndexBuffer()
import Uno.Graphics.Texture2D()
import Uno.Graphics.TextureCube()
import Uno.Graphics.VertexBuffer()

These APIs are scheduled for removal in an upcoming release, because we no longer want to maintain dependencies to the proprietary FBX SDK from Autodesk in our core product.

Syntax sugar

Three new literal types are added in Uno: Points, pixels & hex color codes.

#000         float3(0,0,0)
#FFFF        float4(1,1,1,1)
#FF0000      float3(1,0,0)
#FF0000FF    float4(1,0,0,1)
24.0px       new Uno.UX.Size(24.0f, Uno.UX.Unit.Pixels)
32.0pt       new Uno.UX.Size(32.0f, Uno.UX.Unit.Points)

Preview

• Android preview and export now works for users with spaces in their paths, as long -DGRADLE is used. Note that for this to work with preview, you have to specify the .unoproj explicitly: fuse preview -tandroid my.unoproj -DGRADLE.
• Added Uno.Net.Sockets.TcpListener helper-class for hosting TCP servers. It's a subset of .NETs System.Net.Sockets.TcpListener class, and resolves to that implementation for .NET-targets.

Support for adding Swift files to unoprojs

• Added a Swift file type to unoprojs. Swift files currently do not get the foreign macro expansion that ObjCSource files get.

• The version of Swift to that is used can be configured with the iOS.SwiftVersion project property:

  "iOS": {
    "SwiftVersion": 3.0,
  },
  

  It currently defaults to 3.0.

The following example shows how to use this feature:

Hello.swift:

import Foundation

public class HelloSwiftWorld: NSObject {
    public func hello() {
        print("Hello world!");
    }
}

unoproj:

{
    "Includes": [
        "Hello.swift:Swift:iOS",
        ...
    ]

}

Since Swift can be used from Objective-C, we can call into the Swift code by using Foreign Objective-C, for instance as follows:

[ForeignInclude(Language.ObjC, "@(Project.Name)-Swift.h")]
public class Example
{
    [Foreign(Language.ObjC)]
    public static void DoIt()
    @{
        HelloSwiftWorld* x = [[HelloSwiftWorld alloc] init];
        [x hello];
    @}
}

Gradle

Fix app signing for gradle build on Windows

Misc

Fix the source value 1.5 is obsolete and will be removed in a future release warning.

0.39

Added more control of PList in unoproj

We have added option to specify the following iOS plist entries from the unoproj file:

• NSCalendarsUsageDescription
• NSPhotoLibraryUsageDescription
• NSBluetoothPeripheralUsageDescription
• NSCameraUsageDescription
• NSMicrophoneUsageDescription
• NSAppleMusicUsageDescription
• NSContactsUsageDescription
• NSHomeKitUsageDescription
• NSLocationAlwaysUsageDescription
• NSLocationUsageDescription
• NSLocationWhenInUseUsageDescription
• NSMotionUsageDescription

They can be used as follows:

"iOS": {
    "PList": {
        "NSCameraUsageDescription": "ReasonA",
        "NSMicrophoneUsageDescription": "ReasonB",
        "NSPhotoLibraryUsageDescription": "ReasonC",
    }
}

Foreign Code

Foreign Java is alittle more strict and does a little more type checking during the build.

1. Action<object>s passed to Java will now have the type Action_UnoObject rather than Action_Object Action<Java.Object>s passed to Java will still have the type Action_Object
2. If you make a foreign method with an argument with type object. You must pass an uno object, not a java object.

Here is an example for point 2 that will no longer compile:

[Foreign(Language.Java)]
static string Foo()
@{
   Object jobj = MakeSomeJavaObject();
   @{Bar(object):Call(jobj)};
@}

[Foreign(Language.Java)]
static string Bar(object x)
@{
   ...
@}

The fix for the above would be to change Bar(object x) to Bar(Java.Object x) and @{Bar(object):Call(jobj)} to @{Bar(Java.Object):Call(jobj)}

Gradle Support

• We can now build signed APKs with Gradle.
• For users who run into platform specific filepath length limitations whilst build for Android with Gradle, you can now use the --set:AltBuildPath="/tmp" argument to specify the root of your android builds.

Xcode project generation and signing

• Fix crash occuring when running multiple test fixtures on iOS devices

UX Compiler improvements

• Binding syntax is now supported in shorthands such as <Change foo.bar="{binding}" /> and similar (bugfix).
• Fixed bug where Font and other types that have required UX attributes (constructor arguments) could not be used as ux:Property
• Added basic reactive expression framework to Uno.UX: AddOperator, SubtractOperator etc.

0.38

Xcode project generation and signing

• Added a property to set the Xcode Development Team ID, used for code-signing, in unoprojs:

  {
    "iOS": {
      "DevelopmentTeam": "YOURTEAMID"
    },
    ...
  }
  

  This property can also be set using the --set:Project.iOS.DevelopmentTeam="YOURTEAMID" flag to uno build, e.g.

  uno build iOS --set:Project.iOS.DevelopmentTeam="YOURTEAMID"
  
  

  The Team ID can be found at https://developer.apple.com/account/#/membership/.

• The Development Team ID can also be set user-wide by adding the following to ~/.unoconfig:

  iOS.DevelopmentTeam: "YOURTEAMID"
  

  The file can be created if it doesn't already exist.

• Uno now attempts to automatically find a Development Team ID if it hasn't already been set using either of the above methods. It does so by querying the machine's code-signing identities and selecting the first valid one it finds.

Foreign Java Bugfix

• Fix bug causing build error when returning structs from foreign Java Code

Expand on using Uno arrays from Foreign Java

• Can now pass Uno unsigned byte arrays to foreign Java
• Add ability to make boxed Uno arrays from Java You can now create Uno arrays in Java. To do this you make a new instance of the boxed array types passing in either:
  • the desired length of the Uno array
  • the Java array you want to convert

LongArray ularr = new LongArray(100);
IntArray uiarr = new IntArray(new int[]{1,2,3});

The length constructor works on all the following types. The Java array conversion works on all except the types marked with a *

BoolArray ByteArray CharArray * DoubleArray FloatArray IntArray LongArray ObjectArray * ShortArray StringArray *

0.37

Java foreign code

• Fix crash occuring after wrapping a Java delegate 256 times, due to a leak causing the JNI local reference table to fill up.

Xcode project generation

• We now add the directory of Required Xcode.Frameworks and Xcode.EmbeddedFrameworks to Xcode.FrameworkDirectory, meaning that Xcode.FrameworkDirectory will rarely be necessary to use.

.unoconfig package management (internal)

The following properties are introduced.

Packages.Feeds
Packages.InstallDirectory
Packages.LockFiles

The following properties were renamed for consistency. PackageSourcePaths still works for compatibility.

PackageSearchPaths -> Packages.SearchPaths
PackageSourcePaths -> Packages.SourcePaths
DefaultPackages -> Packages.Default

0.35

• Various internal Uno bugfixes

• In the current release the default minumum sdk version for android builds has been set to 16. This now matches what we have been saying is our minimum supported sdk version. However for those who wish to continue building for older versions of android you and simply add the following to your unoproj file

  "Android": { "SDK": { "MinVersion": "10" } }

or, if you prefer, you can use the following command line argument:

--set:SDK.MinVersion=10

0.34

Foreign code

• Fixed a bug that meant fields accessed using macros that didn't use :Get() in foreign Objective-C, such as @{MyClass:Of(_this)._someField}, did not have their types converted from Uno to their Objective-C equivalents
• Fixed a bug that resulted in foreign code in static constructors not working

Uno parser reimplementation

Faster & harder parser that comes with some minor breaking changes to the syntax.

Previously, some invalid variable declarations were accepted:

var a = 0, b = 0;           // Invalid 'var' with multiple declarators
var c = fixed int[] {0};    // Invalid 'var' with fixed array

Correct syntax is:

int a = 0, b = 0;           // OK
fixed int c[] = {0};        // OK

Xcode project generation

• Added a new property to set the UIBackgroundModes property of the generated Xcode project. You can use it by adding the following to your .unoproj:

  "iOS": {
    "PList": {
      "UIBackgroundModes": [
        "location",
        "voip"
      ]
    }
  }
  

Improved incremental build

• uno build: Don't trigger a build if the previous build is still up-to-date
• Automatically remove outdated files and APK from Android builds

Bugfixes

• unoproj: Allow - in version strings
• Fix crash in ProcessExtensions on Windows

0.33

Preliminary Cocoapod support

Coacoapods is the defacto unofficial standard for iOS package management, until an official package manager support Objective-C (and a bunch of other stuff) cocoapods is a great choice.

Install steps

• brew install ruby
• sudo gem install cocoapods

The cocoapods folks say you should be able to use the ruby that comes with OSX however gem tries to install activesupport v5 as a dependency and this requires at leave Ruby v2.2.2

Using Pods in Uno

build with -DCOCOAPODS to enable cocoapod support.

You can then use the require macro or attribute as follows:

[Require("Cocoapods.Podfile.Target", "pod 'Firebase'")]

0.32

Running on iOS devices

• When building with uno build --target=ios --run, the uno command now stays open, printing any output from the app to stdout. This makes building for Android and iOS behave the same way. (Previously, uno would exit as soon as the app was deployed to the iOS device.)

Compiler bug fixes

• "Using Generic interfaces on nested structs generates faulty C++"
• "Protected member not allowed to be of protected class type"

MSVC target

• Debug using Visual Studio 2015 by default. Will fallback to Visual Studio 2013 when 2015 is unavailable. VS2013 is still required for building the generated code.

0.31

Xcode project generation

• The default setting for frameworks included with the Xcode.EmbeddedFramework element is now to code sign on copy which is also Xcode's default.

• Added a new element for adding shellscripts to the generated Xcode project

  For example, the code

  [Require("Xcode.ShellScript", "someScript")]
  class ...
  

  will add someScript in a PBXProjShellScriptBuildPhase in the generated .pbxproj file.

Foreign code

• Allow passing enums to foreign Objective-C and Java. Enums are passed as their underlying primitive type (which is int by default).

• Fix bug where you couldnt box structs when passed to Foreign Java code

Gradle projects

• To build using experimental gradle support use the -DGRADLE flag

• The Gradle.Dependencies.Compile element has been renamed to Gradle.Dependency.Compile. It's used to specify dependencies in Gradle builds (targeting Android) of the form compile 'XXX'.

  [Require("Gradle.Dependency.Compile", "myDependency")]
  

  results in

  compile 'myDependency'
  

  under dependencies in the generated Gradle build file.

• Added the Gradle.Dependency element for specifying "free-form" dependencies:

  [Require("Gradle.Dependency", "compile('myDependency') { transitive = true }")]
  

  results in

  compile('myDependency') { transitive = true }
  

  under dependencies in the generated Gradle build file.

0.30

Project format

• Support globs in project references

  "Projects": [
    "projects/**/*.unoproj"
  ]
  

• New default DeploymentTarget on iOS

  The new iOS target is 8.0. You can edit the default in your .unoproj.

  "iOS.DeploymentTarget": "8.0"
  

Other changes (internal)

• Add new pack, push (usable now) & install, feed (not yet) commands.
• Add Uno.Compiler.Extensions who consists of Bindings, Foreign & Plugins.
• Rename some root directories to lower case.
  • Later, we'll also want to rename the remaining directories
    • Library/Core -> lib
    • Source -> src

0.29

Project format

• Transitive references.

  Given the projects App, A & B:
  * App refences A, which has a transitive reference to B.
  * This means that App has a implicit reference to B through A.
  

  You can use transitive references in your project file like this:

  "IsTransitive": true
  

  This will make all references in your project transitive, effectively making your project a transitive package.

• New default package names (Android) and bundle identifiers (iOS)

  • By default we use the string com.apps.@(Project.Name) converted to lower case.
  • This was done to solve collisions in the file system causing builds to fail.
  • On iOS, _ is replaced by - because _ are not allowed in bundle identifiers.

  If you want to override the defaults, you can edit your .unoproj.

  "Android.Package": "com.domain.my_app"
  

  "iOS.BundleIdentifier": "com.domain.my-app"
  

  Users that have apps in app stores probably want something that fits their app or organization, rather than the defaults.

0.28

Bugfixes

• Fixed an erratic crash while performing HTTP-requests in MSVC and CMake targets.

CLI improvements

• Add no-build command.

  This allows deferring --build, --debug & --run without triggering a full uno build. Options are simplified but similar to uno build, please see uno no-build --help.

  One example:

  cd <project-dir>
  uno build ios --no-native
  uno no-build ios --build --run
  

  Thanks to @bolav for suggesting this feature.

Other goodies

• C++/MSVC: Add *.natvis files for Visual Studio. This makes debugger better able to visualize Uno objects.
• build: Use .lock during build (or clean) for exclusive access to project.

Architecture (internal)

• Clean up Uno.Common.dll and Uno.Compiler.API.dll
• Factor out Uno.Compiler.Foreign.dll (work in progress)
• Factor out Uno.Compiler.Plugins.dll (work in progress)
• Add diagrams, see https://github.com/fusetools/Uno/tree/master/Source
• This breaks Fuse, but a migration branch exists at https://github.com/fusetools/Fuse/tree/feature-uno

NuGet & UPM packages (internal)

• In TeamCity, .NUPKGs for upload to UPM are now produced from core Uno packages and included in upload.zip.
• A X-platform NuGet package for C# including Uno.Compiler.API.dll and Uno.Common.dll is also produced on Windows agents.

0.27

• Add Uno.Permissions. Currently this is android only but will be expanded to iOS in due course. It supports both the old Android static permissions and the newer request based permissions.

• All Uno projects now include the android 'support-v4' library. This means there is no longer a dedicated uno package for 'support-v4'`

0.26

Foreign Code

• Fixed a bug which resulted in comments not working in foreign Objective-C.
• Added support for writing constructors using foreign code.
• Foreign Objective-C code is now automatically wrapped in an Objective-C @autoreleasepool.

out/ref

• Added support for using interfaces as parameters to foreign Objective-C functions.

• Added support for out and ref parameters in foreign Objective-C functions. The Objective-C type for such a parameter is a pointer to the Objective-C type of the parameter according to the old rules.

The following two examples show how it works:

[Foreign(Language.ObjC)]
extern(iOS) void PrimitiveOutParam(ref int m, out int n)
@{
    // m and n are of type `int*` here.
    *m = 222;
    *n = 123;
@}

[Foreign(Language.ObjC)]
extern(iOS) void StringOutParam(ref string m, out string n)
@{
    // m and n are of type `NSString**` here.
    *m = @"Out1";
    *n = @"Out2";
@}

As Java doesnt have out/ref parameters, it is very unlikely that we will support this for Java.

ForeignInclude

You can now use the ForeignInclude attribute to:

• Add header files in ObjC
• Add imports in Java

It can only be used on classes. The includes affect all Foreign methods in the uno class.

[ForeignInclude(Language.Java, "java.lang.Runnable", "java.lang.Boolean", "android.app.Activity")]
[ForeignInclude(Language.ObjC, "Example.hh")]
public class SomeUnoClass : Uno.Application
{
    ...
}

UX Compiler improvements

• this is now the implicit name of the current ux:Class or ux:InnerClass root node.

0.25

API changes

• Added Uno.IO.Bundle and Uno.IO.BundleFile
• Removed old Uno.BundleFile

C++ changes

• Changes in base libraries (uno-base)

  • Xli/Foo.h -> uBase/Foo.h
  • Xli::Foo -> uBase::Foo
  • ...

  Ask us on slack/#uno if you get problems.

UXL

• Required Xcode.Frameworks that have file extensions now do not get an additional .framework extension.

ux:Global support for value types

You can now create ux:Global objects of value types, such as float4. This is convenient e.g. for creating global color constants.

ux:InnerClass

• Added support for ux:InnerClass, which is a class that has access to named UX objects in its scope. Specifically, the differences are:

  ux:Class

    Declares a global class that can be used anywhere.
    Such classes have no access to ux:Names the scope in which they are declared.
  

  ux:InnerClass

    Declares a class that can only be used in the scope where it is declared.
    In return, it has full access to all ux:Names in the scope it is declared.
  
    Inner classes can be extracted into separate .ux files, and then included
    using <ux:Include File="Foo.ux"> in the scope you want to use it.
  
    Inner classes can not specify namespaces, they will implicitly be in the
    name scope of their containing class.
  
    If root nodes are marked ux:InnerClass, they are ignored by the UX compiler
    unless ux:Included somewhere.
  

Foreign code

• Added support for processed foreign files

  An include file in an Uno project with type ObjCSource or ObjCHeader will have any UXL macros pre-processed in the same way that such macros are expanded in Foreign Code blocks. The macro expansion requires the file to be an Objective-C++ file (it uses features from both C++ and Objective-C to interoperate with Uno code), and that the file uObjC.Foreign.h has been included.

• Added support for passing delegates to and from foreign Objective-C functions

  Delegates get converted to an Objective-C block of the corresponding type. As an example, an argument of the type Func<string, int, object> becomes a block of type ^ id<UnoObject>(NSString*, int). The argument and return type of the block use the same type conversions as arguments to foreign functions normally do.

• Added support for passing arrays to foreign Objective-C functions

  Arrays are converted to an object of type id<UnoArray> which is a wrapper around the Uno array. It can be indexed and updated with the familiar arr[i] syntax and has a count method (called with [arr count]) that returns an NSUInteger. Note that updates to it are reflected in the original Uno array --- it's a wrapper, not a copy. It's also possible to copy the id<UnoArray> to an NSArray* by calling [xs copyArray].

  Since Objective-C lacks generics, indexing into the id<UnoArray> object to get an element returns id regardless of the element type of the array on the Uno side. This id is a boxed representation of the element type according to the following table:

  Uno	Objective-C	Boxed array element
  int, bool, char, etc.	int, bool, char	NSNumber*
  string	NSString*	NSString*
  ObjC.Object	id	id
  object	id<UnoObject>	id<UnoObject>
  Func<string, int> etc.	^ int(NSString*)	^ int(NSString*)
  SomeType[]	id<UnoArray>	id<UnoArray>

  Most types are already boxed, but note that primitive types like int, bool, and char are boxed as NSNumber* when accessed in a wrapped array. This means that to update an Uno array argument int[] x on the Objective-C side, we have to write e.g. x[index] = @42;. When copying an array, the resulting NSArray*'s elements are also boxed following the same rules.

  It's possible to circumvent the boxing behaviour by using good old UXL macros. The following examples contrast the two ways to use arrays in foreign Objective-C code:

  [Foreign(Language.ObjC)]
  public static extern(iOS) void ForeignIntArray(int[] xs)
  @{
      @{int[]:Of(xs).Set(3, 123)};
      for (int i = 0; i < @{int[]:Of(xs).Length:Get()}; ++i)
      {
          NSLog(@"array[%d]=%d", i, @{int[]:Of(xs).Get(i)});
      }
  @}

  [Foreign(Language.ObjC)]
  public static extern(iOS) void ForeignIntArray(int[] xs)
  @{
      xs[3] = @123;
      for (int i = 0; i < [xs count]; ++i)
      {
          NSLog(@"array[%d]=%@", i, xs[i]);
      }
  @}

• Added support for passing uno arrays to foreign Java functions

Just like with ObjC we can now pass arrays. And like ObjC there are some language specific details.

First off we try to avoid copying massive ammounts of data by default, so we pass up a boxed uno array. You can then call .copyArray() on that to get the native array (at which point the data is copied)

The conversions look like this (Note: Java does not allow generics of primitives types)

| Uno Type              | Boxed Java Type      | Unboxed Java Type   |
|-----------------------|----------------------|---------------------|
| bool[]                | com.uno.BoolArray    | bool[]              |
| sbyte[]               | com.uno.ByteArray    | byte[]              |
| char[]                | com.uno.CharArray    | char[]              |
| short[]               | com.uno.ShortArray   | short[]             |
| int[]                 | com.uno.IntArray     | int[]               |
| long[]                | com.uno.LongArray    | long[]              |
| float[]               | com.uno.FloatArray   | float[]             |
| double[]              | com.uno.DoubleArray  | double[]            |
| string[]              | com.uno.StringArray  | String[]            |
| anyOtherType[]        | com.uno.ObjectArray  | com.uno.UnoObject[] |

Java also doesn't allow operator overloading so to get the first int from an IntArray called x use x.get(0). To set first value in the IntArray x to 10 use x.set(0, 10)

• Added support for passing uno delegate to foreign Java functions

You can now use uno delegate types in your foreign java functions.

So if you define a delegate like this

```uno
namespace Foo
{
   public delegate void Bar(float x, float y, float z);
}
```

Then you can do this:

```uno
[Foreign(Language.Java)]
public static extern(Android) void ForeignDelegate(Bar x)
@{
    x.run(1.0f, 2.0f, 3.0f);
@}
```

Now 'Java < 8' doesn't have lambdas, and runnable and callables don't take arguments, so behind the scenes the compiler makes a java class called com.foreign.Foo.Bar with a public void run(float x, float y, float z) { ... } method.

The usual type conversion for primitive, string, objects & arrays still apply to arguments of delegates.

You can also pass uno Actions to Java. Again because Java delegates don't support primitives we have to generate a class for this.

The type conversions follow this pattern:

```uno
Action -> com.foreign.Uno.Action
Action<int> -> com.foreign.Uno.Action_int
Action<int[],int> -> com.foreign.Uno.Action_IntArray_int
```

0.24

C++ backend

• Fixed a bug where the finally block in a try-finally statement was not run if the try block returned.

Internal changes

• Renamed Dependencies/ -> Prebuilt/
• Renamed uno browse -> uno disasm
• Removed outdated uno run
• No longer need Xamarin Studio installed to build on OS X
• Solutions removed, Uno.sln is generated when running build (Windows) or make
• New .unoconfig syntax
  • Append operator: SearchPaths += [ foo bar ]
  • Includes: include <filename>
    • Works when file doesn't exist
    • Supports wildcard: include *.unoconfig

0.23

Uno language

• Added @(Macro) and @keyword

  string projectName = @(Project.Name);
  string @enum = "this strings name is a keyword";

  @(Macro) expressions allows you to access settings from your Uno project, UXL or the command-line. The return value is always string.

  Uno supports built-in macros which will return different values based on context.

  Built-in macro	Returns
  @(FILE)	Path to the current source file.
  @(LINE)	Number of the current line.
  @(DIRNAME)	Path to the parent directory of @(FILE).
  @(PACKAGE)	Name of the package containing @(FILE).
  @(PACKAGE_DIR)	Root directory of @(PACKAGE).
  @(PACKAGE_VERSION)	Version of @(PACKAGE).

• Added [Attribute] on enum literals

  enum Foo
  {
      [Bar]
      Baz = 1
  }

Internal changes

• Package format changed

  This means your package library must be updated.

  • From source: make clean && make
  • From stuff: Make sure you got the newest stuff.

• uno doctor optimization

  uno doctor -a runs about 20-30 seconds faster/roughly twice as fast because of caching.

• Root scripts moved to Scripts/ and Tests/

  UNIX users should use make instead of running the scripts directly:

  • make -> Run Scripts/build.sh
  • make clean -> Run Scripts/clean.sh
  • make release -> Run Scripts/pack.sh
  • make test -> Run Tests/test.sh

  build.bat and clean.bat kept in root for now because of missing make on Windows.

0.21

UX markup

• Bugfixes for ux:Property

  • This release fixes many issues related to the ux:Property feature.

• Changes to ux:Property

  A node marked with ux:Property no longer represents the default value, but just a definition of the property. The default value has to be specified either on the containing class node, for example:

    <App Theme="Basic">
        <Panel ux:Class="MyPanel" ux:Name="self" Paint="#f00">
            <Brush ux:Property="Paint"/>
  
            <Rectangle Fill="{Property self.Paint}"/>
        </Panel>
        <Panel>
            <MyPanel Paint="#00f" />
        </Panel>
    </App>
  

  Note that for {Property self.Paint} to work, the declared property type has to exactly match the type where it is used (Brush).

  You can also use ux:Binding to set a complex object as default value:

        <Panel ux:Class="MyPanel" ux:Name="self" >
            <Brush ux:Property="Paint"/>
  
            <LinearGradient ux:Binding="Paint">
                <GradientStop Offset="0" Color="#f00" />
                <GradientStop Offset="1" Color="#0f0" />
            </LinearGradient>
  
            <Rectangle Fill="{Property self.Paint}"/>
        </Panel>
  

• New feature : ux:Include

  • BREAKING CHANGE: UX Markup files with no ux:Class on the root node no longer produce a class based on the file name. You have to explicitly set a class name on the file's root node (ux:Class="ClassName"). The UX compiler will politely tell you how to fix this in a compile-time error message.

  • <ux:Include File="Foo.ux" /> will copy/paste include another UX file at the given location. This will make it easier to split large UX components into separate files.

Uno language

• Foreign code blocks

  Uno methods marked with the [Foreign(Language.LANGAGE)] attribute, where LANGUAGE is ObjC or Java can be written in the foreign language provided the function body is written inside "foreign braces": @{ ... @}.

  Foreign functions automatically convert the arguments and return value from their Uno representation to a corresponding foreign language representation.

  Primitive (int, char, float, etc) types are converted to the corresponding primitive type in the foreign language.

  Other types are automatically converted in both directions according to the following tables:

  Uno	Java
  string	String
  Java.Object	Object
  object	UnoObject

  Uno	Objective-C
  string	NSString*
  ObjC.Object	id
  object	id<UnoObject>

  We can see that we have UnoObject to wrap Uno objects on the foreign side, and {Java,ObjC}.Object to wrap foreign objects on the Uno side.

  UXL macros such as Call (@{Type:Of(thing).Method(argTypes):Call(args)}), Set, and Get can be used to call back to Uno code from the foreign code block with reversed type conversions.

  If the foreign method is an instance method, the foreign code block can additionally access the wrapped this object in the automatically added _this parameter.

• New Uno project file types CSource, CHeader, and Java

  These can be used instead of having to add the file as a File in the Uno project and then using <ProcessFile {Header,Source}File="filename" /> in an extensions file.

• Conditional file inclusion in Uno projects

  Using

  "Includes": [
    "file.ext:FileType:CONDITION"
  ]

  in a project file includes the file only in builds fulfilling CONDITION (e.g. Android, iOS).

• Require attribute

  [Require("Key", "Value")] can now be used on Uno classes and methods in place of specifying <Require Key="Value" /> separately in an extensions file.

• extern statements (@{...@})

  You can pass arguments, similar to extern expressions.

  int arg = 10;
  ...
  extern(arg)
  @{
      printf("%d", $0);
  @}

  When only access to method arguments is needed, the extern header can be omitted.

  void foo(int arg)
  ...
  @{
      printf("%d", $0);
  @}

Build system

• New iOS build settings

  • Added new project properties

    "iOS": {
        "BundleIdentifier": "com.uno.$(Name)",
        "BundleName": "$(Title)",
        "DeploymentTarget": "7"
    },

    These plist options are supported by Uno projects:

    • UIRequiredDeviceCapabilities
    • MKDirectionsApplicationSupportedModes
    • NSHealthShareUsageDescription
    • NSHealthUpdateUsageDescription
    • UIApplicationExitsOnSuspend
    • UIFileSharingEnabled
    • UINewsstandApp
    • UIPrerenderedIcon
    • UIRequiresPersistentWiFi
    • UISupportedExternalAccessoryProtocols
    • UIViewControllerBasedStatusBarAppearance
    • UIViewEdgeAntialiasing

    This is an example plist section of an unoproj using this feature:

    "iOS": {
        "PList": {
            "MKDirectionsApplicationSupportedModes": [
                "MKDirectionsModeCar",
                "MKDirectionsModeBus",
            ],
            "UIRequiresPersistentWiFi": true,
            "UIRequiredDeviceCapabilities": [
                "camera-flash"
            ]
        },
    },

  • Added a new UXL element called Xcode.EmbeddedFramework for adding embedded frameworks to the generated Xcode project.

  • Absolute paths to frameworks in Xcode.Framework elements are now allowed. This means that the following ways to include frameworks are accepted:

    <Require Xcode.Framework="some.framework" /> <-- relative to SDKROOT/System/Library/Frameworks/ as before
    <Require Xcode.Framework="/path/to/some.framework" /> <-- absolute path
    <Require Xcode.Framework="@('some.framework':Path)" /> <-- relative to UXL file

    The .framework extension is optional and will be added automatically if omitted.

• Improved Android support

  • Android Studio support (experimental)

    Uno projects can now be opened in Android Studio, making it easier to debug native code on device. Type uno build android --debug to launch Android Studio directly from the command line. Tested using Android Studio version 1.5 which can be downloaded from here: http://developer.android.com/tools/studio/index.html

  • New project structure

    In order to support Android Studio, we had to adapt to the new "Gradle" project structure, involving moving files around in the generated project. AndroidManifest.xml for example, can be found under @(Project.Name)/app/src/main instead of in the root output directory. Java source files are written to @(Project.Name)/app/src/main/java instead of src. Use the @(Java.SourceDirectory) macro to refer to the java source directory.

  • New APK launcher

    Some Windows users has been getting stuck on "Uninstalling APK" when trying to deploy APKs. This is usually because "Developer Mode" isn't enabled on the device, missing USB drivers, or the device is not properly connected. The new APK launcher is now able to print a better error message and terminate, instead of getting stuck.

    The new launcher will also print logcat output from the device while app is running.

    See uno launch-apk -h for more. You can pass launch-apk options through uno build android -a"OPTIONS".

  • Added ADB wrapper

    You can use uno adb [args] if you need to run adb from the Android SDK without adding "platform-tools" to PATH.

  • Added Android SDK Manager wrapper

    You can use uno android if you need to open the Android SDK Manager.

  • Improved "space support", so Android users can enjoy...

    • ...projects containing spaces in the name
    • ...projects containing spaces in the path
    • ...Android SDK and NDK installed in a location containing spaces in the path

  • New Uno project settings for SDK configuration

    If you have specific requirements regarding SDK, you can now control those with the following properties:

    "Android": {
      "NDK": {
        "PlatformVersion": null     // default: 9
      },
      "SDK": {
        "BuildToolsVersion": null,  // default: 23.0.0
        "CompileVersion": null,     // default: 19
        "MinVersion": null,         // default: 10
        "TargetVersion": null       // default: 19
      }
    },

    We do however recommend to keep null for automatic detection of settings based on the current SDK installed on the build machine (fuse install android).

  • Fixed a problem causing mkdir to sometimes fail on Windows

  • Updated native compilers to GCC 4.9

• New project build directory defaults

  "BuildDirectory": "build",
  "CacheDirectory": ".uno",
  "OutputDirectory": "$(BuildDirectory)/@(Target)/@(Configuration)"

  The reason for this is that the old build directory starting with a . gets hidden by default in OS X, causing some confusion. E.g. when you want to open the build output in another program that doesn't support showing hidden files, the non-dotted directory is now much easier to find.

  If this cause trouble, you can pass --out-dir to uno build to override, or configure your project using these old settings:

  "BuildDirectory": ".build",
  "CacheDirectory": ".cache",
  "OutputDirectory": "$(BuildDirectory)/@(Target)-@(Configuration)"

  Remember to update your .gitignores.

• uno build improvements

  • The following targets where renamed, but you can still use the old name:

    New name	Old name
    MSVC	MSVC12
    DotNet	DotNetExe

  • The --debug argument is supported by the following targets:

    Build target	Action
    Android	Opens Android Studio
    CMake	Opens Xcode (OS X only)
    iOS	Opens Xcode (OS X only)
    MSVC	Opens Visual Studio 2013 (Windows only)

    If the project is already open in an IDE/debugger, we won't open any additional windows. You can use --debug as often as you want without being worried about getting spammed by new windows.

    --debug will disable the native compile step in Uno, and enable native debugging, so that you can build and debug from the IDE. Otherwise --debug is short hand for --run-args=debug, and will pass debug as an argument to the run script. This may fail without error if used on an unsupported build target.

  • Specify target without --target

    For example, to build for Android:

    uno build android
    

  • Added new shorthand arguments:

    • -N -> --no-native (Disable native compile step)
    • -S -> --no-strip (Disable removal of unused code)
    • -d -> --debug (Open IDE for debugging)

  • C++ debugging flags can be passed on the command line:

    • -DDEBUG_UNSAFE (Enable asserts in unsafe code)
    • -DDEBUG_ARC1..4 (Print debug info from memory manager)
    • -DDEBUG_DUMPS (Dumps object graphs to disk for analysis)

• UXL changes

  • New macro operators

    Macro	Input	Output
    @(FOO:EscapeSpace)	foo bar	foo\ bar
    @(FOO:QuoteSpace)	foo bar	"foo bar"

  • Tolerant XML syntax

    The UXL parser is able to handle attributes and inner text containing non-encoded XML entities. Quotes are optional on simple attribute values, such as numbers and booleans. For example, this is now accepted by the parser:

    <Define UNIX />
    <Set Foo=1 Condition="FOO && BAR" />
    <Expression>a < b</Expression>
    <Expression>a < b</Expression>

    Instead of, compared to strict XML:

    <Define UNIX="UNIX" />
    <Set Foo="1" Condition="FOO &amp;&amp; BAR" />
    <Expression><![DATA[a < b]]></Expression>
    <Expression>a &lt; b</Expression>

Internal changes

• uno doctor rewrite to handle standard library development more efficiently

  It's now better at detecting what projects needs to be built or not. This improvement fixes bugs and saves time.

  Rebuild specific package(s) Foo and Bar from the command line:

  uno doctor Foo Bar
  

  See uno doctor -h for more.

• No more NuGet or git submodules

  NuGet and git submodules are completely removed from this repository forever. This improves build times (10-30s) and just makes the repository easier to deal with.

  C# dependencies are managed by Stuff™, and the source is available on G-hub: https://ghub.com/fusetools/uno-dependencies

• Updated to Stuff™ version 1.0.5

  Fixes file lock bugs and adds some new syntax:

  • !, ||, () are now supported in conditional expressions
  • else if is now supported, to complement if..else statements

• .unoconfig: PackageBuildPaths was renamed to PackageSourcePaths (deprecated)

0.19

Uno.Http fixes

• Change Uri.Encode and Uri.Decode to treat space as %20, like RFC 2396 and the rest of the world agrees on.
• Change Uri.Encode to not percent-encode tilde and single quotes, in accordance with RFC 2396.
• Make Uri.Encode and Uri.Decode grok UTF-8.

0.18

General changes

• Smaller installer footprint

  Platform specific binaries (Xli, V8, FMOD, ...) used by Uno packages are no longer included in the installer, but downloaded on demand if needed during build. This enables us to remove some large and not-always-needed binary files from the installer, making the download ~30MB smaller on each platform. This also introduces uno stuff, a simple built-in package manager.

• Integrated uno doctor, test, perf-test and perf-cmp commands

  uno doctor replaces StdLibBuilder. Use whenever the package library needs updating. In addition, the --libs switch can be used on uno build to update on demand. The redundant unotest and performancetest commands were removed -- use uno test and uno perf-test instead. See https://github.com/fusetools/Uno#command-reference.

• Append to path arrays in .unoconfig

  Personal/project specific .unoconfig files can now append additional paths using $(LastPathArray). For example:

    PackageSearchPaths: [
        $(LastPathArray)
        "MyPackages/.build"
    ]
    PackageBuildPaths: [
        $(LastPathArray)
        "MyPackages"
    ]

• Less verbose build log

  uno build will produce minimal output by default. Add -v, -vv or -vvv if you need more output.

• Better --version

  uno --version will now present the correct version.

• Various performance and stability fixes

iOS fixes

• Add iOS.BundleVersion project property to set plist property CFBundleVersion on iOS.
• Fix launching Xcode simulator on iPhone 6. Previously only older generations worked.

API changes

• Generics and partial reflection support in Uno.Type

  Almost 30 new members are introduced in Uno.Type, modelled after System.Type in .NET. This enables runtime generic type support. See https://github.com/fusetools/Uno/commit/b49635699dd64b08c2673a1cf3844ee13ab37101 for details.

• Use correct return type for bitwise operators

  This affects the following types: byte, sbyte, short and ushort.

UXL changes

• Array macros

  • Create arrays using @{ELEMENT_TYPE:Array([ELEMENTS, ...])} or @{ELEMENT_TYPE[]:New(SIZE)}
  • Access elements using @{ARRAY:Get(INDEX)} and @{ARRAY:Set(INDEX, VALUE)}

• Renamed C++ specific elements and properties

  The old names will generate a warning when used. Just replace with the new name for silence.

  New name	Old name
  TypeName	InstanceTypeName
  FileExtension	Source.FileExtension
  SourceFile	Build.SourceFile
  HeaderFile	Build.HeaderFile
  PreprocessorDefinition	Build.PreprocessorDefinition
  LinkLibrary	Build.LinkLibrary
  LinkDirectory	Build.LinkDirectory
  IncludeDirectory	Build.IncludeDirectory
  Xcode.Framework	iOS.Build.Framework
  Xcode.PrefixHeader.Declaration	iOS.PrefixHeader.Declaration

• Renamed CIL specific properties

  The old names will generate a warning when used. Just replace with the new name for silence.

  New name	Old name
  Assembly	AssemblyReference

• Preprocessor improvement

  #if..#endif directives will expand to comments containing the disabled code instead of blank lines, when false.

C++ improvements

• C++ API changes

  As the C++ code generator is more or less rewritten, the underlying C++ APIs are cleaned up too. This doesn't affect regular Uno code, but may affect handwritten code using the C++ APIs directly.

  • Most notably, the following methods were changed in Uno/ObjectModel.h:

    New method	Old method
    uArray::New(arrayType, length, [data])	uNewArray(elementType, length, [data])
    uString::Ansi(cstr, [length])	uNewStringAnsi(cstr, [length])
    uString::Utf8(cstr, [length])	uNewStringUtf8(cstr, [length])
    uString::Const(cstr)	uGetStringConst(cstr)
    uAllocCStr(string)	uStringToCStr(string)

    Note that uArray::New() now expects arrayType directly rather than elementType, for better cache usage.

  • And these methods in Uno/Memory.h:

    New method	Old method
    uRetain(object)	uRetainObject(object)
    uRelease(object)	uReleaseObject(object)
    uAutoRelease(object)	uAutoReleaseObject(object)

  • Some fields were given better names. For example, uArray::_len -> _length.

  • Xli.h, the all including header, was removed. Include a more specific header instead. For example Xli/Mutex.h.

  Just ask in #uno on our slack community if you need help.

• Runtime parameterization and reflection of generic classes and methods

  • 100% code sharing between generic parameterizations, reducing the amount of C++ code generated by 30-40% (default Fuse project, --no-strip, MSVC12)

  • Creation of new type parameterizations at run time using reflection, which for example helps the Fuse UX simulator in terms of robustness

  The new C++ APIs powering this are found in the Uno/ObjectModel.h header.

• General dynamic invoke

  Any Uno method can be invoked by function pointer using a single C++ function: void uInvoke(const void* func, void** args, size_t count). To make this possible we've changed the calling convention when using function pointers. All function pointers must return void while any parameters and return value is passed by pointer. This allowed us to remove a lot of C++ template clutter, enabling faster compilation and better code.

• Less call stack clutter

  Previously nearly all method calls resulted in two entries in the call stack because of wrapping. Now there's just one entry for common method calls, when not being invoked using a delegate or interface. This should help make the call stacks less deep and easier to navigate. Many generated methods also get cleaner C++ names (Object::New() vs. Object__New()).

• Keyword awareness

  Uno is aware of keywords and other reserved words, and will rename as necessary to not produce any conflicts. A list of words for C++ is found in UXL: https://github.com/fusetools/Uno/blob/master/Library/Core/UnoCore/Targets/CPlusPlus/Config.cpp.uxl#L68

• Most runtime hash look ups eliminated

  • String constants are cached and loaded from static fields
  • Type objects are cached and loaded from static fields (in most cases)
  • import will generate static fields instead of using a Dictionary based runtime system

  This fixes serious performance problems in some cases, for example in code where string constants are used heavily.

• Faster interface look ups

  O(log n) virtual method table look up, instead of O(n). is and as operators are also faster.

• Array initializers

  Emit array initializers, e.g. uArray::Init<int>(Int__typeof(), 2, 0, 1), instead of unrolling the expression and setting all the elements individually. This makes the generated C++ code smaller and easier to read.

• Type initializers

  Implement runtime support for type initializers, instead of generating code using a compiler transform. This enables support for static generic fields, and generates somewhat cleaner and better behaving code. Static constructors are invoked lazily and are called before accessing a static member on the declaring type, or instantiation an object of the type.

• Release build by default

  Use release settings when building the generated C++ code. Debug is still the default for Uno code.

  When common case is to not run the code using a C++ debugger, optimized settings should be the default as they make the code run significantly faster. Specify -O0 for unoptimized build when debugging.

• iOS: --run on device, or -adebug in Xcode

  uno build -tios --run will build an iOS app and launch it on a connected device, instead of opening Xcode. Pass -adebug when you want to open Xcode.

• MSVC12: Added -adebug flag

  uno build -tmsvc12 -adebug will open the Visual Studio project ready for debugging, instead of running the executable.

• Various code generator bug fixes

  Fixed a bug where passing a reference field through ref or out didn't work, and some other cases of valid code that didn't compile.

• Less Xcode warnings produced when building for iOS and OS X

Test runner improvements

• Added timers

  Print how many microseconds (μs) spent running each test, in addition to total time spent building and testing.

• Less verbose output

  Only warnings (if any) and STDERR are printed from the build log. Use -v if you need more output.

• Tests are now run in alphabetical order

Internal changes

• Makefile

  You can now build Uno using make on all platforms. The following targets are available: all, clean, install and min. (The MakeRunner package for Atom is nice.)

• Renamed Library and Dependencies folders

  Instead of StdLib and Stuff. This removes frustration when attempting to type St<TAB> in a terminal, and it looks more presentable when we go open source eventually.

• Renamed Scripts/bin folder and added uno-dev script

  uno-dev was added to avoid collisions with installed uno. The other wrappers formerly located in Scripts/Commands were removed -- use uno test / uno-dev test and similar commands instead.

• Code base clean up

  Major naming/structure clean up, and merging of compiler assemblies. The core compiler logic is split between the following assemblies: Uno.Compiler.API (BackendFramework, IL, Bytecode), Uno.Compiler.Frontend (Parser, AST, UXL), Uno.Compiler.Core, and backend specific assemblies. Otherwise the C# code base is organized in two root directories: Source and Tools. See https://github.com/fusetools/Fuse/commit/135a9b65526efacf20906df7d1ddbdf8f57b2bf7 for details.

• Migration branches

  The following migration branches are currently active:

  • https://github.com/fusetools/fuselibs/tree/feature-uno
  • https://github.com/fusetools/unolibs/tree/feature-uno
  • https://github.com/fusetools/Android/tree/feature-uno
  • https://github.com/fusetools/iOS/tree/feature-uno
  • https://github.com/fusetools/Fuse/tree/feature-uno

• Improved Fuse/Uno link script

  The new link-uno script on Fuse works on both Windows (with MSYS) and OS X/Linux, and will create symlinks to the Uno binaries instead of copying them. This means that you won't need to rerun the script when making changes to Uno. Just make sure to rebuild Fuse, from Visual Studio if you prefer. The new $(LastPathArray) feature in Unoconfig also makes the experience more robust. The build-uno variants are hopefully redundant now. See https://github.com/fusetools/Fuse/commit/90d88c42ebccc05f2473ef517622ae0d9d3e0604.

• Added -DSIMULATOR to replace --preview-mode

  This is fixed on Fuse/feature-uno in https://github.com/fusetools/Fuse/commit/6952f989148fc58b7ee62d2bd7bc3510b4f9ae3b.

Internal changes

• Minor changes in Project class (https://github.com/fusetools/Uno/commit/e97febe18fdd1f47c58a1edb143ec56b65442b83)

Glob notes

These glob features are supported:

• Brace Expansion
• Extended glob matching
• "Globstar" ** matching

Patterns without / in .unoproj or .unoignore files are matched recursively.

*             # Matches all files
*.foo         # Mathces all files named *.foo
*.bar         # Matches all files named *.bar
*.+(bar|foo)  # Matches all files named *.bar or *.foo
foobar        # Matches all files named foobar

Prefixing with / or ./ disables recursion.

/*.png        # Not recursive, matches all PNG files found directly in project directory

Use globstar (**) for explicit recursion.

Foo/**/*.uno  # Mathces all files named *.uno in Foo directory recursively

2015/06/26

New features

• Compact logging. Compiler will produce alot less output by default. Use uno build -v to enable verbose output.
• Conditional compilation. Platform-specific code that won't be needed is completely culled, which improves performance. This introduces new syntax that replaces [ExportCondition] (see: Porting Notes).
• Multithreaded parser. Parsing is now performed on several threads in parallel to improve performance.
• New define: MOBILE (replaces ANDROID || IOS).
• New define: DOTNET (replaces CIL || CSHARP).

Porting notes

Previously platform-specific types and members were decorated with [ExportCondition] attributes for conditional usage by different build targets. Because attribues requires compilation before the information can be properly resolved, we've introduced a new extern(EXPRESSION) modifier in order to cull these entities before anything is compiled. This reduces the work load for the compiler significantly.

In addition, if defined(EXPRESSION) syntax is introduced for conditional compilation. If EXPRESSION evaluates to false, code inside the block won't be compiled because entities referred inside the block might have been culled (producing compile error). defined(EXPRESSION) ?: expressions implements the same behaviour.

In order to stay backwards compatible in most cases, [ExportCondition("EXPRESSION")] is automatically rewritten to extern(EXPRESSION) by the parser. Code like if (defined(ANDROID) || defined(IOS)) is rewritten to if defined(ANDROID || IOS) when possible. More advanced cases must be broken up by hand.

Any compile errors introduced by upgrading to this version can usually be fixed by adding if defined(...) tests or extern(...) modifiers. Otherwise help is available on slack.

Before:

[ExportCondition("ANDROID")]
class AndroidClass
{
}

After:

extern(ANDROID) class AndroidClass
{
}

This change in behaviour also happens to make things like this now possible:

class Foo
{
    extern(ANDROID) void Bar()
    {
        // Android specific code
    }

    extern(IOS) void Bar()
    {
        // iOS specific code
    }

    void Method()
    {
        if defined(ANDROID || IOS)
            Bar();
    }
}

Internal changes

• C++ reflection API (Uno.Reflection.CppReflection). Build with uno build -DREFLECTION to enable.
• C++ backend: CppClassWriter is split into CppType and CppGenerator.
• Several other optimizations/refactorings.

2015/06/23

New features

• Added a more compact JSON project format (old XML will still be loaded without problems).
• JSON project format supports implicit files when omitting the Includes property, the project directory will then be scanned for files automatically. An Excludes property is also provided.
• CIL backend: UXL <Require Assembly="System.Core" /> now supports linking assemblies from the Global Assembly Cache (GAC) in addition to plain DLL filenames.

Internal changes

• Project.Files is now known as Project.IncludeItems, Project.ExludeItems, and Project.FlattenedItems (managed automatically)
• Project.PackageReferences, Project.ProjectReferences and similar properties are changed to IReadOnlyList<T>. When editing the project use the new properties Project.MutablePackageReferences, Project.MutableProjectReferences and so on. Using the mutable variants will invalidate the project and cause it to regenerate Project.FlattenedItems.
• Project.ResolveBuildDirectory(Logger log) and similar are now replaced by properties Project.BuildDirectory and so on.

Next release

• HTTP: Renamed Experimental.Net.Http to Uno.Net.Http
• HTTP: Enabled support for caching by default
• HTTP: Removed SetContentType, use SetHeader("Content-type", "text/javascript") instead
• HTTP: New Android implementation
• HTTP: New iOS implementation
• HTTP: Removed outdated HttpClient, it's recommended to create your own wrapper around HttpMessageHandler instead.

0.1.542 (2015/05/22)

Internal changes

• Packages are now shipped with version numbers. If you have projects referring to version 0.1.0, a warning will be printed, and the latest package version will be used instead. To remove the warning, simply delete 'Version="0.1.0" from your .unoproj.

0.1.466 (2015/05/12)

New features

• CLI: Adding -D<define> and -U<define> switches for specifying defines
• CLI: Improved uno update. It will now scan the project directory and add/remove files automatically. Use .unoignore to specify excludes.
• C++ backend: Put all generated code in a global namespace app::. This reduces the chance of Uno entities colliding with native C++ entities.
• UXL (Android): Renamed properties Makefile.SharedLibrary and Makefile.StaticLibrary to JNI.SharedLibrary and JNI.StaticLibrary

Internal changes
