Changelog (pre 0.60)

This file contains all changelogs for releases in the pre-0.60 range. Please check out the other CHANGELOG-*.md files for newer versions.

v0.59.10

This is likely the last patch release for version 59 of React Native for the foreseeable future: it contains an important Android side update for the JavaScript Core, to prevent a great number of crashes mostly related to Samsung devices - thanks to @Kudo for his work on fixing this via 557989a86f!

Thanks everyone who participated in the discussion.

v0.59.9

This is a patch fix release addressing a couple ScrollView regressions, and "future-proof" RN 59 from crashes caused by upgrading Gradle (now can support up to 5.4.1 & 3.4.0 for the plugin) and Xcode 11 Beta 1. You can upgrade to this version without upgrading your tooling.

Thanks everyone who contributed code or participated in the discussion for cherry-picking commits. You can participate to the conversation for the next patch release in the dedicated issue.

Changed

  • If isInteraction is not specified in the config, it would always default to true which would block interactions like VirtualizedList updates. This is generally not what you want with useNativeDriver since the animation won't be interrupted by JS. If something does end up interfering with an animation and causes frame drops, isInteraction can be set manually. (8f186b84ae by @sahrens)

  • Update detox to match master (c6a5c09e2b by @kelset)

v0.58.1

There were some regressions with developer tools that prevented react-native run-ios from working properly in 0.58.0; this patch fix addresses that.

Thanks everyone who contributed code or participated in the discussion for cherry-picking commits - you can participate to the decision process for the next patch release here.

v0.58.0

Welcome to first stable release of React Native of 2019! There are a number of significant changes in this version, and we'd like to especially draw your attention to them:

  • Modernizing and strengthening flow types for core components
  • Breaking changes to ScrollView, CameraRollView, and SwipeableRow that make it no longer bound to the component instance in certain methods
  • Support for mutual TLS in WebKit
  • Asset serving from directories besides /assets
  • Numerous crash fixes and resolutions for unexpected behavior

Aside from those:

  • if you are an iOS developer, you'll need to manually link JavaScriptCore.framework when upgrading; this can be done via Xcode, and following the steps shown here.

  • Android developers, please note that Android's target SDK 27 is supported. Work is still underway to land target SDK 28 support, and it will come soon.

Thanks to those who gave feedback during the release candidate phase. If you're interested in helping evaluate our next release (0.59), subscribe to the dedicated issue here.

Added

  • Add support for publicPath to enable serving static assets from different locations (0b314960aa by @gdborton)
  • Add TouchableBounce now has a simple bounce() function that can be used to trigger a bounce without callbacks (7fe3f90156)

Android specific

  • Bundler server host can now be set using Android System Properties, making for easier debugging across multiple apps or app installs adb shell setprop metro.host (e02a154787 by @stepanhruda)
  • Native Modules can now reject a promise with an additional WritableMap arg for extra properties (userInfo). See the interface defined in Promise.java for available methods. This is accessible in JavaScript as Error.userInfo. This is to match iOS's existing Error.userInfo behavior. See PR for examples. (#20940 by @Salakar)
  • Native Modules now expose a nativeStackAndroid property to promises rejected with an Exception/Throwable - making native error stacks available inside Javascript: Error.nativeStackAndroid. This is to match iOS's existing Error.nativeStackIOS support. See PR for examples. (#20940 by @Salakar)

iOS specific

Changed

Breaking Changes 💥

  • Public methods of components converted to ES6 classes are no longer bound to their component instance. For ScrollView, the affected methods are setNativeProps, getScrollResponder, getScrollableNode, getInnerViewNode, scrollTo, scrollToEnd, scrollWithoutAnimationTo, and flashScrollIndicators. For CameraRollView, the affected methods are: rendererChanged. For SwipeableRow, the affected methods are: close. Therefore, it is no longer safe to pass these method by reference as callbacks to functions. Auto-binding methods to component instances was a behaviour of createReactClass that we decided to not preserve when switching over to ES6 classes. (you can refer to this example)

  • Native Modules in Android now require @ReactModule annotations to access .getNativeModule method on the ReactContext. This is how your updated Native Module should look like:

    // CustomModule.java

// ...
+  import com.facebook.react.module.annotations.ReactModule;

+  @ReactModule(name="CustomBridge")
public class CustomModule extends ReactContextBaseJavaModule {
  // ...

  @Override
  public String getName() {
      return "CustomBridge";
  }

  // ...
}

  • Fix race condition and crash around shutdown of the JSC for iOS 11 and earlier (bf2500e38e by @mhorowitz)
  • Fix crash in NetInfo's _firstTimeReachability (eebc8e230a by @mmmulani)

  • Fix case where inline view is visible even though it should have been truncated (70826dbafc by @rigdern)

Known issues

It is possible that you'll face an AAPT error regarding missing resources, here is an example of this error, in this case, you should try to update the build tools versions to buildToolsVersion = "28.0.2" in your android/build.gradle file. If you maintain a react-native library which uses native code you should avoid using hardcoded versions of the build tools and use the packaged version numbers, here is an example you can follow

Known issues

There are a few issues that don't have a finalized solution (as it happens for 0.x projects). In particular:

  • when using Xcode 10 and react-native init, your build may fail due to third-party build steps (#20774). There is a commit we are planning to cherry pick in a future release that should help - in the meantime, you should be able to run these commands from the project folder to fix the issue (you should need to do it only once per project):

    cd node_modules/react-native
scripts/ios-install-third-party.sh
cd third-party/glog-0.3.5/
../../scripts/ios-configure-glog.sh

  • React 16.6.0 works for the most part, aside from the Context API (check this issue) - and if you are eager to test the new React Hooks you will have to be patient, as they are not production ready and 16.7.alpha is not yet supported by React Native.

v0.57.0

Welcome to the 0.57 release of React Native! This release addresses a number of issues and has some exciting improvements. We again skipped a monthly release, focused on quality by extending the release candidate phase, and let some upstream packages reach stable for inclusion.

This release includes 599 commits by 73 different contributors! In response to feedback, we've prepared a changelog that contains only user-impacting changes. Please share your input and let us know how we can make this even more useful, and as always let us know if you have any feedback on this process.

Highlights

New features

  • Accessibility APIs now support accessibility hints, inverted colors, and easier usage of defining the element's role and states; read more at @ziqichen6's excellent blog post
  • On iOS, WKWebView can now be used within the WebView component; read more at @rsnara's awesome blog post
  • Better support for out-of-tree platforms. For details, please refer to the discussion that the community used to get this up and running (there will be a new page in the docs dedicated to it too) - huge props to @empyrical for working on this!

Tooling updates

  • Android tooling has been updated to match newer configuration requirements (SDK 27, gradle 4.4, and support library 27); building with Android plugin 3.2 doesn't work due to the gradle scripts, so please stay on Android Studio 3.1 for now
  • Support Babel 7 stable landed! Be sure to read here about using TypeScript and check out the Babel 7 migration guide for help migrating.
  • Metro has been upgraded (with Babel 7 and better transformer support), and in the next major release we plan on having two new features (ram bundles and inline requires) optional for you all to use - you can read how it will happen here; moreover, if you have a custom packager config, we recommend you read also the "updating to this version" section.
  • Flow, React, and related packages have also been updated; this includes working support for the React Profiler.

The Slimmening is happening

As mentioned a few times in the past, the core team is reviewing the repository to trim it to the base React Native features in order to make the whole ecosystem more maintainable (by using a divide-et-impera approach, the community will move faster and enable pull requests to be reviewed and merged quicker). This change requires extracting some components into their own separate repos and removing old, unused code (details here).

0.57 is not directly affected by any changes, but we want you to know that:

  • WebView will be moved to its own repo at react-native-community/react-native-webview. There is already a base implementation there. Help us out by giving that a try, and expect that WebView will be deprecated soon
  • NavigatorIOS will be fully removed from the main codebase starting 0.58.0 (via this commit); it is now deprecated

Updating to this version

  1. Upgrade the version of React Native in the package.json from 0.56.0 to 0.57.0, and the React version to 16.5

  2. Change the babel-preset dependency from "babel-preset-react-native": "^5", to "metro-react-native-babel-preset": "^0.45.0",, then change the .babelrc configuration to:

      {
    "presets": ["module:metro-react-native-babel-preset"]
  }

  3. Ensure that you have all the babel dependencies to version ^7.0.0 (you may also need to add "babel-core": "7.0.0-bridge.0" as a yarn resolution to ensure retro-compatibility). The Babel team has released a tool, babel-upgrade, that should help you in this migration.

  4. Upgrading android gradle version to 4.4

    1. In your project's android/gradle/wrapper/gradle-wrapper.properties file, change the distributionUrl to https\://services.gradle.org/distributions/gradle-4.4-all.zip
    2. In android/build.gradle file add google() right above jcenter() in both buildscript and allprojects repositories. Then change Android build tools to version 3.1.4 classpath 'com.android.tools.build:gradle:3.1.4'
    3. In android/app/build.gradle file update all your compile statements to be implementation, e.g. implementation 'com.facebook.fresco:animated-gif:1.10.0'
    4. Do note that when running your app from within Android Studio, you may encounter Missing Byte Code errors. This is due to a known issue with version 3.1.x of the android tools plugin. You'll need to disable Instant Run to get past this error.

  5. If you have a custom packager configuration via rn-cli.config.js, you probably need to update it to work with the updated Metro configuration structure (for full detail refer to Metro's documentation); here are some commonly encountered changes to rn-cli.config.js:

    -const blacklist = require('metro/src/blacklist')
+const blacklist = require('metro-config/src/defaults/blacklist')

// ...

module.exports = {
+  watchFolders: alternateRoots,
+  resolver: {
+    blacklistRE: blacklist
+  },
+  transformer: {
+    babelTransformerPath: require.resolve('./scripts/transformer.js'),
+  },
-  getProjectRoots() {
-    return [
-      path.resolve(__dirname),
-    ].concat(alternateRoots)
-  },
-  getBlacklistRE() {
-    return blacklist;
-  },
-  transformModulePath: require.resolve('./scripts/transformer.js'),
}

  6. Run yarn to ensure that all the new dependencies have been installed

Android specific additions

iOS specific additions

Changes: existing functionality that is now different

Breaking Changes

  • Public methods of Image (blur, focus, measure, measureInWindow, measureLayout, setNativeProps) are no longer bound to the image component instance. Therefore, it is unsafe to pass these methods by reference (i.e: as callbacks) to functions. So, things like setTimeout(this._imgRef.focus, 1000) will no longer work. Please instead do: setTimout(() => this._imgRef.focus(), 1000).

v0.56.0

Welcome to the June 2018 release of React Native! Over 60 contributors made 821 commits since March - and we are extremely grateful to every single one of you.

As you'll see in a second, this new version has some important breaking changes that required a lot of extra efforts to bring to a stable 0.56. This was the main reason behind skipping April and May from the monthly release cycle, but looking forward we are planning on going back to do a rollout every month.

Highlights

React Native now uses Babel 7

When upgrading to 0.56, make sure to bump your babel-preset-react-native package.json dependency to 5.0.2 or newer (but still as fixed value).

React Native library authors will need to update their libraries to make use of the updated Babel preset as Babel 7 is not backwards compatible.

If you have issues upgrading to Babel 7, please double check the related documentation, in particular the sections related to Package Renames and Scoped Packages.

The babel-bridge library may be used if you need to use libraries that have not yet upgraded to Babel 7. You may also enforce the Babel 7 dependency via tools like yarn resolutions. Overall, you need to ensure all the @babel/* deps are fixed at version 7.0.0-beta.47.

Node 8 is now the minimum required version

Trailing commas are now allowed.

iOS 9 is now the minimum required version

Any device that can run iOS 8, can upgrade to iOS 9. Developers who support iOS 8 in their apps may continue doing so as this is a Xcode-level setting (IPHONEOS_DEPLOYMENT_TARGET).

Xcode 9 is now the minimum required version

We recommend using Xcode 9.4 as that is what we use to run our tests.

Android projects are now compiled using the Android 26 SDK

The target API level is left unchanged in this release.

Starting August 2018, new apps submitted to the Play Store will need to target API 26 as a minimum. You can now opt your project in to use API 26 (or newer) as the target. Please let us know about any issues, as we'd like to finalize support for Android API 26 by the time 0.57.0 is released.

WebView will only load http(s) URLs by default

Geolocation is disabled by default.

Consistently Throw for <Text><View /></Text>

Removes a pitfall that people may run into when releasing an app for Android if the bulk of the testing has been performed on iOS only. Nesting a <View> within a <Text> component (e.g. <Text><View /></Text>) is unsupported on Android, but using this pattern on iOS has not thrown errors in the past. With this release, nesting a <View> inside a <Text> will now throw an error on iOS in order to reduce the parity gap between the platforms.

Flow improvements, migrating away from PropTypes

Added Flow types for several components.

We're migrating away from PropTypes and runtime checks and instead relying on Flow. You'll notice many improvements related to Flow in this release.

  • Fix project settings warnings on newer Xcode versions, remove unnecessary console logging.
  • Modernized YellowBox. Sort warnings by recency, group warnings by format string, present stack traces, show status of loading source maps, support inspecting each occurrence of a warning, and bug fixes.
  • Prettier files!
  • Lots of bug fixes.

State of React Native

Heads-up: the Facebook internal team is currently working on a rewrite of some core architecture pieces. This is a work in progress and we do not expect it to be ready for use in open source quite yet, but we felt the need to let you know what those commits mentioning Fabric are about.

Changes: existing functionality that is now different

Breaking Changes

  • Public methods of Text (blur, focus, measure, measureInWindow, measureLayout, setNativeProps) are no longer bound to the text component instance. It is therefore unsafe to pass these methods by reference (i.e: as callbacks) to functions. So, things like setTimeout(this._txtRef.focus, 1000) will no longer work. Please instead do: setTimeout(() => this._txtRef.focus(), 1000).

Known issues

During the RC testing of this version, a few issues that have been opened don't have yet a finalized solution ( 19827, 19763, 19859, 19955 ). We are aware of them and we hope that by releasing 0.56.0 the surface of developers interacting to find solutions to them will allow for faster resolution and an even better 0.56.1 release. So please check the already opened issues before submitting new ones.

If you are using Windows to develop React Native apps, we suggest you keep an eye on this issue in particular since there have been many reports of issues related to Win 10 and RN 0.56.
