+Version 1.19.0 (2017-07-20)
+  
+===========================
+  
+
+  
+Language
+  
+--------
+  
+
+  
+- [Numeric fields can now be used for creating tuple structs.][41145] [RFC 1506]
+  
+  For example `struct Point(u32, u32); let x = Point { 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] [RFC 1624]
+  
+  For example: `let x = loop { break 7; };`
+  
+- [C compatible `union`s are now available.][42068] [RFC 1444] They can only
+  
+  contain `Copy` types and cannot have a `Drop` implementation.
+  
+  Example: `union Foo { bar: u8, baz: usize }`
+  
+- [Non capturing closures can now be coerced into `fn`s,][42162] [RFC 1558]
+  
+  Example: `let foo: fn(u8) -> u8 = |v: u8| { v };`
+  
+
+  
+Compiler
+  
+--------
+  
+
+  
+- [Add support for bootstrapping the Rust compiler toolchain on Android.][41370]
+  
+- [Change `arm-linux-androideabi` to correspond to the `armeabi`
+  
+  official ABI.][41656] If you wish to continue targeting the `armeabi-v7a` ABI
+  
+  you should use `--target armv7-linux-androideabi`.
+  
+- [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.
+  
+- [The compiler now supports Visual Studio 2017][42225]
+  
+- [The compiler is now built against LLVM 4.0.1 by default][42948]
+  
+- [Added a lot][42264] of [new error codes][42302]
+  
+- [Added `target-feature=+crt-static` option][37406] [RFC 1721] Which allows
+  
+  libraries with C Run-time Libraries(CRT) to be statically linked.
+  
+- [Fixed various ARM codegen bugs][42740]
+  
+
+  
+Libraries
+  
+---------
+  
+
+  
+- [`String` now implements `FromIterator<Cow<'a, str>>` and
+  
+  `Extend<Cow<'a, str>>`][41449]
+  
+- [`Vec` now implements `From<&mut [T]>`][41530]
+  
+- [`Box<[u8]>` now implements `From<Box<str>>`][41258]
+  
+- [`SplitWhitespace` now implements `Clone`][41659]
+  
+- [`[u8]::reverse` is now 5x faster and `[u16]::reverse` is now
+  
+  1.5x faster][41764]
+  
+- [`eprint!` and `eprintln!` macros added to prelude.][41192] Same as the `print!`
+  
+  macros, but for printing to stderr.
+  
+
+  
+Stabilized APIs
+  
+---------------
+  
+
+  
+- [`OsString::shrink_to_fit`]
+  
+- [`cmp::Reverse`]
+  
+- [`Command::envs`]
+  
+- [`thread::ThreadId`]
+  
+
+  
+Cargo
+  
+-----
+  
+
+  
+- [Build scripts can now add environment variables to 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 out a local working directory for the
+  
+  crates.io index][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 support for custom target specific runners][cargo/3954]
+  
+
+  
+Misc
+  
+----
+  
+
+  
+- [Added `rust-windbg.cmd`][39983] for loading rust `.natvis` files in the
+  
+  Windows Debugger.
+  
+- [Rust will now release XZ compressed packages][rust-installer/57]
+  
+- [rustup will now prefer to download rust packages with
+  
+  XZ compression][rustup/1100] over GZip packages.
+  
+- [Added the ability to escape `#` in rust documentation][41785] By adding
+  
+  additional `#`'s ie. `##` is now `#`
+  
+
+  
+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.
+  
+- [As a result of the `-Z` flag change, the `cargo-check` plugin no
+  
+  longer works][42844]. Users should migrate to the built-in `check`
+  
+  command, which has been available since 1.16.
+  
+- [Ending a float literal with `._` is now a hard error.
+  
+  Example: `42._` .][41946]
+  
+- [Any use of a private `extern crate` outside of its 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.
+  
+- [From the pound escape, lines consisting of multiple `#`s are
+  
+  now visible][41785]
+  
+- [It is an error to reexport private enum variants][42460]. This is
+  
+  known to break a number of crates that depend on an older version of
+  
+  mustache.
+  
+- [On Windows, if `VCINSTALLDIR` is set incorrectly, `rustc` will try
+  
+  to use it to find the linker, and the build will fail where it did
+  
+  not previously][42607]
