-Version 1.8.0 (2016-04-14)
-==========================
-
-Language
---------
-
-* Rust supports overloading of compound assignment statements like
-  `+=` by implementing the [`AddAssign`], [`SubAssign`],
-  [`MulAssign`], [`DivAssign`], [`RemAssign`], [`BitAndAssign`],
-  [`BitOrAssign`], [`BitXorAssign`], [`ShlAssign`], or [`ShrAssign`]
-  traits. [RFC 953].
-* Empty structs can be defined with braces, as in `struct Foo { }`, in
-  addition to the non-braced form, `struct Foo;`. [RFC 218].
-
-Libraries
----------
-
-* Stabilized APIs:
-  * [`str::encode_utf16`][] (renamed from `utf16_units`)
-  * [`str::EncodeUtf16`][] (renamed from `Utf16Units`)
-  * [`Ref::map`]
-  * [`RefMut::map`]
-  * [`ptr::drop_in_place`]
-  * [`time::Instant`]
-  * [`time::SystemTime`]
-  * [`Instant::now`]
-  * [`Instant::duration_since`][] (renamed from `duration_from_earlier`)
-  * [`Instant::elapsed`]
-  * [`SystemTime::now`]
-  * [`SystemTime::duration_since`][] (renamed from `duration_from_earlier`)
-  * [`SystemTime::elapsed`]
-  * Various `Add`/`Sub` impls for `Time` and `SystemTime`
-  * [`SystemTimeError`]
-  * [`SystemTimeError::duration`]
-  * Various impls for `SystemTimeError`
-  * [`UNIX_EPOCH`]
-  * [`AddAssign`], [`SubAssign`], [`MulAssign`], [`DivAssign`],
-    [`RemAssign`], [`BitAndAssign`], [`BitOrAssign`],
-    [`BitXorAssign`], [`ShlAssign`], [`ShrAssign`].
-* [The `write!` and `writeln!` macros correctly emit errors if any of
-  their arguments can't be formatted][1.8w].
-* [Various I/O functions support large files on 32-bit Linux][1.8l].
-* [The Unix-specific `raw` modules, which contain a number of
-  redefined C types are deprecated][1.8r], including `os::raw::unix`,
-  `os::raw::macos`, and `os::raw::linux`. These modules defined types
-  such as `ino_t` and `dev_t`. The inconsistency of these definitions
-  across platforms was making it difficult to implement `std`
-  correctly. Those that need these definitions should use the `libc`
-  crate. [RFC 1415].
-* The Unix-specific `MetadataExt` traits, including
-  `os::unix::fs::MetadataExt`, which expose values such as inode
-  numbers [no longer return platform-specific types][1.8r], but
-  instead return widened integers. [RFC 1415].
-* [`btree_set::{IntoIter, Iter, Range}` are covariant][1.8cv].
-* [Atomic loads and stores are not volatile][1.8a].
-* [All types in `sync::mpsc` implement `fmt::Debug`][1.8mp].
-
-Performance
------------
-
-* [Inlining hash functions lead to a 3% compile-time improvement in
-  some workloads][1.8h].
-* When using jemalloc, its symbols are [unprefixed so that it
-  overrides the libc malloc implementation][1.8h]. This means that for
-  rustc, LLVM is now using jemalloc, which results in a 6%
-  compile-time improvement on a specific workload.
-* [Avoid quadratic growth in function size due to cleanups][1.8cu].
-
-Misc
-----
-
-* [32-bit MSVC builds finally implement unwinding][1.8ms].
-  i686-pc-windows-msvc is now considered a tier-1 platform.
-* [The `--print targets` flag prints a list of supported targets][1.8t].
-* [The `--print cfg` flag prints the `cfg`s defined for the current
-  target][1.8cf].
-* [`rustc` can be built with an new Cargo-based build system, written
-  in Rust][1.8b].  It will eventually replace Rust's Makefile-based
-  build system. To enable it configure with `configure --rustbuild`.
-* [Errors for non-exhaustive `match` patterns now list up to 3 missing
-  variants while also indicating the total number of missing variants
-  if more than 3][1.8m].
-* [Executable stacks are disabled on Linux and BSD][1.8nx].
-* The Rust Project now publishes binary releases of the standard
-  library for a number of tier-2 targets:
-  `armv7-unknown-linux-gnueabihf`, `powerpc-unknown-linux-gnu`,
-  `powerpc64-unknown-linux-gnu`, `powerpc64le-unknown-linux-gnu`
-  `x86_64-rumprun-netbsd`. These can be installed with
-  tools such as [multirust][1.8mr].
-
-Cargo
------
-
-* [`cargo init` creates a new Cargo project in the current
-  directory][1.8ci].  It is otherwise like `cargo new`.
-* [Cargo has configuration keys for `-v` and
-  `--color`][1.8cc]. `verbose` and `color`, respectively, go in the
-  `[term]` section of `.cargo/config`.
-* [Configuration keys that evaluate to strings or integers can be set
-  via environment variables][1.8ce]. For example the `build.jobs` key
-  can be set via `CARGO_BUILD_JOBS`. Environment variables take
-  precedence over config files.
-* [Target-specific dependencies support Rust `cfg` syntax for
-  describing targets][1.8cfg] so that dependencies for multiple
-  targets can be specified together. [RFC 1361].
-* [The environment variables `CARGO_TARGET_ROOT`, `RUSTC`, and
-  `RUSTDOC` take precedence over the `build.target-dir`,
-  `build.rustc`, and `build.rustdoc` configuration values][1.8cv].
-* [The child process tree is killed on Windows when Cargo is
-  killed][1.8ck].
-* [The `build.target` configuration value sets the target platform,
-  like `--target`][1.8ct].
-
-Compatibility Notes
--------------------
-
-* [Unstable compiler flags have been further restricted][1.8u]. Since
-  1.0 `-Z` flags have been considered unstable, and other flags that
-  were considered unstable additionally required passing `-Z
-  unstable-options` to access. Unlike unstable language and library
-  features though, these options have been accessible on the stable
-  release channel. Going forward, *new unstable flags will not be
-  available on the stable release channel*, and old unstable flags
-  will warn about their usage. In the future, all unstable flags will
-  be unavailable on the stable release channel.
-* [It is no longer possible to `match` on empty enum variants using
-  the `Variant(..)` syntax][1.8v]. This has been a warning since 1.6.
-* The Unix-specific `MetadataExt` traits, including
-  `os::unix::fs::MetadataExt`, which expose values such as inode
-  numbers [no longer return platform-specific types][1.8r], but
-  instead return widened integers. [RFC 1415].
-* [Modules sourced from the filesystem cannot appear within arbitrary
-  blocks, but only within other modules][1.8m].
-* [`--cfg` compiler flags are parsed strictly as identifiers][1.8c].
-* On Unix, [stack overflow triggers a runtime abort instead of a
-  SIGSEGV][1.8so].
-* [`Command::spawn` and its equivalents return an error if any of
-  its command-line arguments contain interior `NUL`s][1.8n].
-* [Tuple and unit enum variants from other crates are in the type
-  namespace][1.8tn].
-* [On Windows `rustc` emits `.lib` files for the `staticlib` library
-  type instead of `.a` files][1.8st]. Additionally, for the MSVC
-  toolchain, `rustc` emits import libraries named `foo.dll.lib`
-  instead of `foo.lib`.
