+Version 1.19.0 (2017-07-20)
+===========================
+
+Language
+--------
+
+- [Numeric fields can now be used for creating tuple structs.][36868]
+  For example `struct Point(u32, u32); let x = Foo { 0: 7, 1: 0 };`.
+- [Macro recursion limit increased to 1024 from 64.][41676]
+- [Added lint for detecting unused macros.][41907]
+- [`loop` can now return a value with `break`.][42016]
+  For example: `let x = loop { break 7; };`
+- [C compatible `union`s are now available.][42068] They can only contain `Copy`
+  types and cannot have a `Drop` implementation.
+  Example: `union Foo { bar: u8 }`
+
+Compiler
+--------
+
+- [Added bootstrap support for Android.][41370]
+- [Change `arm-linux-androideabi` to correspond to the `armeabi`
+  official ABI.][41656]
+- [Fixed ICE when removing a source file between compilation sessions.][41873]
+- [Minor optimisation of string operations.][42037]
+- [Compiler error message is now `aborting due to previous error(s)` instead of
+  `aborting due to N previous errors`][42150] This was previously inaccurate and
+  would only count certain kinds of errors.
+- [Now supports Visual Studio 2017][42225]
+- [Added a lot][42264] of [new error codes][42302]
+
+Libraries
+---------
+
+- [`String` now implements `FromIterator<Cow<'a, str>>` and
+  `Extend<Cow<'a, str>>`][41449]
+- [`Vec` now implements `From<&mut [T]>`][41530]
+- [`SplitWhitespace` now implements `Clone`][41659]
+- [`[u8]::reverse` is now 5x faster and `[u16]::reverse` is now
+  1.5x faster][41764]
+
+Compatibility Notes
+-------------------
+
+- [`MutexGuard<T>` may only be `Sync` if `T` is `Sync`.][41624]
+- [`-Z` flags are now no longer allowed to be used on the stable
+  compiler.][41751] This has been a warning for a year previous to this.
+- [Ending a float literal with `._` is now a hard error.
+  Example: `42._` .][41946]
+- [Ending a str literal with an underscore is now a hard error
+  Example: `"foo"_`][41990]
+- [Publicly exposing a private type is now a hard error][34537] This was
+  previously a warning.
+- [Type parameter defaults in trait impls and functions is now a
+  hard error][36887] This was previously a warning.
+- [`use` imports on a private `extern crate` in a module is now a hard
+  error.][36886] This was previously a warning.
+- [`use ::self::foo;` is now a hard error.][36888] `self` paths are always
+  relative while the `::` prefix makes a path absolute, but was ignored and the
+  path was relative regardless.
+- [Floating point constants in match patterns is now a hard error][36890]
+  This was previously a warning.
+- [Struct or enum constants that don't derive `PartialEq` & `Eq` used
+  match patterns is now a hard error][36891] This was previously a warning.
+- [Lifetimes named `'_` are no longer allowed.][36892] This was previously
+  a warning.
+
+Misc
+----
+
+- [Added `rust-windbg.cmd`][39983] for loading rust `.natvis` files in the
+  Windows Debugger.
+- [Rust Language Server is now packaged as a non default component with the
+  `.exe`, `.msi`, and `.pkg` installers][42306]
+
+Cargo
+-----
+
+- [Build scripts can now add environment variables the environment
+  the crate is being compiled in.
+  Example: `println!("cargo:rustc-env=FOO=bar");`][cargo/3929]
+- [Subcommands now replace the current process rather than spawning a new
+  child process][cargo/3970]
+- [Workspace members can now accept glob file patterns][cargo/3979]
+- [Added `--all` flag to the `cargo bench` subcommand to run benchmarks of all
+  the members in a given workspace.][cargo/3988]
+- [Updated `libssh2-sys` to 0.2.6][cargo/4008]
+- [Target directory path is now in the cargo metadata][cargo/4022]
+- [Cargo no longer checks the crates.io index locally][cargo/4026] This should
+  provide smaller file size for the registry, and improve cloning times,
+  especially on Windows machines.
+- [Added an `--exclude` option for excluding certain packages when using the
+  `--all` option][cargo/4031]
+- [Cargo will now automatically retry when receiving a 5xx error
+  from crates.io][cargo/4032]
+- [The `--features` option now accepts multiple comma or space
+  delimited values.][cargo/4084]
+- [Added a GNU make jobserver implementation to Cargo.][cargo/4110]
