+Version 1.18.0 (2017-06-08)
+===========================
+
+Language
+--------
+
+- [Stabilize pub(restricted)][40556] `pub` can now accept a module path to
+ make the item visible to just that module tree. Also accepts the keyword
+ `crate` to make something public to the whole crate but not users of the
+ library. Example: `pub(crate) mod utils;`. [RFC 1422].
+- [Stabilize `#![windows_subsystem]` attribute][40870] conservative exposure of the
+ `/SUBSYSTEM` linker flag on Windows platforms. [RFC 1665].
+- [Refactor of trait object type parsing][40043] Now `ty` in macros can accept
+ types like `Write + Send`, trailing `+` are now supported in trait objects,
+ and better error reporting for trait objects starting with `?Sized`.
+- [0e+10 is now a valid floating point literal][40589]
+- [Now warns if you bind a lifetime parameter to 'static][40734]
+- [Tuples, Enum variant fields, and structs with no `repr` attribute or with
+ `#[repr(Rust)]` are reordered to minimize padding and produce a smaller
+ representation in some cases.][40377]
+
+Compiler
+--------
+
+- [rustc can now emit mir with `--emit mir`][39891]
+- [Improved LLVM IR for trivial functions][40367]
+- [Added explanation for E0090(Wrong number of lifetimes are supplied)][40723]
+- [rustc compilation is now 15%-20% faster][41469] Thanks to optimisation
+ opportunities found through profiling
+- [Improved backtrace formatting when panicking][38165]
+
+Libraries
+---------
+
+- [Specialized `Vec::from_iter` being passed `vec::IntoIter`][40731] if the
+ iterator hasn't been advanced the original `Vec` is reassembled with no actual
+ iteration or reallocation.
+- [Simplified HashMap Bucket interface][40561] provides performance
+ improvements for iterating and cloning.
+- [Specialize Vec::from_elem to use calloc][40409]
+- [Fixed Race condition in fs::create_dir_all][39799]
+- [No longer caching stdio on Windows][40516]
+- [Optimized insertion sort in slice][40807] insertion sort in some cases
+ 2.50%~ faster and in one case now 12.50% faster.
+- [Optimized `AtomicBool::fetch_nand`][41143]
+
+Stabilized APIs
+---------------
+
+- [`Child::try_wait`]
+- [`HashMap::retain`]
+- [`HashSet::retain`]
+- [`PeekMut::pop`]
+- [`TcpStream::peek`]
+- [`UdpSocket::peek`]
+- [`UdpSocket::peek_from`]
+
+Cargo
+-----
+
+- [Added partial Pijul support][cargo/3842] Pijul is a version control system in Rust.
+ You can now create new cargo projects with Pijul using `cargo new --vcs pijul`
+- [Now always emits build script warnings for crates that fail to build][cargo/3847]
+- [Added Android build support][cargo/3885]
+- [Added `--bins` and `--tests` flags][cargo/3901] now you can build all programs
+ of a certain type, for example `cargo build --bins` will build all
+ binaries.
+- [Added support for haiku][cargo/3952]
+
+Misc
+----
+
+- [rustdoc can now use pulldown-cmark with the `--enable-commonmark` flag][40338]
+- [Added rust-winbg script for better debugging on Windows][39983]
+- [Rust now uses the official cross compiler for NetBSD][40612]
+- [rustdoc now accepts `#` at the start of files][40828]
+- [Fixed jemalloc support for musl][41168]
+
+Compatibility Notes
+-------------------
+
+- [Changes to how the `0` flag works in format!][40241] Padding zeroes are now
+ always placed after the sign if it exists and before the digits. With the `#`
+ flag the zeroes are placed after the prefix and before the digits.
+- [Due to the struct field optimisation][40377], using `transmute` on structs
+ that have no `repr` attribute or `#[repr(Rust)]` will no longer work. This has
+ always been undefined behavior, but is now more likely to break in practice.
+- [The refactor of trait object type parsing][40043] fixed a bug where `+` was
+ receiving the wrong priority parsing things like `&for<'a> Tr<'a> + Send` as
+ `&(for<'a> Tr<'a> + Send)` instead of `(&for<'a> Tr<'a>) + Send`
+- [Overlapping inherent `impl`s are now a hard error][40728]
+- [`PartialOrd` and `Ord` must agree on the ordering.][41270]
+- [`rustc main.rs -o out --emit=asm,llvm-ir`][41085] Now will output
+ `out.asm` and `out.ll` instead of only one of the filetypes.
+- [ calling a function that returns `Self` will no longer work][41805] when
+ the size of `Self` cannot be statically determined.
+- [rustc now builds with a "pthreads" flavour of MinGW for Windows GNU][40805]
+ this has caused a few regressions namely:
+
+ - Changed the link order of local static/dynamic libraries (respecting the
+ order on given rather than having the compiler reorder).
+ - Changed how MinGW is linked, native code linked to dynamic libraries
+ may require manually linking to the gcc support library (for the native
+ code itself)

+Version 1.17.0 (2017-04-27)
+===========================
+
+Language
+--------
+
+* [The lifetime of statics and consts defaults to `'static`][39265]. [RFC 1623]
+* [Fields of structs may be initialized without duplicating the field/variable
+ names][39761]. [RFC 1682]
+* [`Self` may be included in the `where` clause of `impls`][38864]. [RFC 1647]
+* [When coercing to an unsized type lifetimes must be equal][40319]. That is,
+ there is no subtyping between `T` and `U` when `T: Unsize<U>`. For example,
+ coercing `&mut [&'a X; N]` to `&mut [&'b X]` requires `'a` be equal to
+ `'b`. Soundness fix.
+* [Values passed to the indexing operator, `[]`, automatically coerce][40166]
+* [Static variables may contain references to other statics][40027]
+
+Compiler
+--------
+
+* [Exit quickly on only `--emit dep-info`][40336]
+* [Make `-C relocation-model` more correctly determine whether the linker
+ creates a position-independent executable][40245]
+* [Add `-C overflow-checks` to directly control whether integer overflow
+ panics][40037]
+* [The rustc type checker now checks items on demand instead of in a single
+ in-order pass][40008]. This is mostly an internal refactoring in support of
+ future work, including incremental type checking, but also resolves [RFC
+ 1647], allowing `Self` to appear in `impl` `where` clauses.
+* [Optimize vtable loads][39995]
+* [Turn off vectorization for Emscripten targets][39990]
+* [Provide suggestions for unknown macros imported with `use`][39953]
+* [Fix ICEs in path resolution][39939]
+* [Strip exception handling code on Emscripten when `panic=abort`][39193]
+* [Add clearer error message using `&str + &str`][39116]

+
+Compatibility Notes
+-------------------
+
+* [Rust 1.17 does not correctly detect the MSVC 2017 linker][38584]. As a
+ workaround, either use MSVC 2015 or run vcvars.bat.
+* [When coercing to an unsized type lifetimes must be equal][40319]. That is,
+ disallow subtyping between `T` and `U` when `T: Unsize<U>`, e.g. coercing
+ `&mut [&'a X; N]` to `&mut [&'b X]` requires `'a` be equal to `'b`. Soundness
+ fix.
+* [`format!` and `Display::to_string` panic if an underlying formatting
+ implementation returns an error][40117]. Previously the error was silently
+ ignored. It is incorrect for `write_fmt` to return an error when writing
+ to a string.
+* [In-tree crates are verified to be unstable][39851]. Previously, some minor
+ crates were marked stable and could be accessed from the stable toolchain.
+* [Rust git source no longer includes vendored crates][39728]. Those that need
+ to build with vendored crates should build from release tarballs.
+* [Fix inert attributes from `proc_macro_derives`][39572]
+* [During crate resolution, rustc prefers a crate in the sysroot if two crates
+ are otherwise identical][39518]. Unlikely to be encountered outside the Rust
+ build system.
+* [Fixed bugs around how type inference interacts with dead-code][39485]. The
+ existing code generally ignores the type of dead-code unless a type-hint is
+ provided; this can cause surprising inference interactions particularly around
+ defaulting. The new code uniformly ignores the result type of dead-code.
+* [Tuple-struct constructors with private fields are no longer visible][38932]
+* [Lifetime parameters that do not appear in the arguments are now considered
+ early-bound][38897], resolving a soundness bug (#[32330]). The
+ `hr_lifetime_in_assoc_type` future-compatibility lint has been in effect since
+ April of 2016.
+* [rustdoc: fix doctests with non-feature crate attributes][38161]
+* [Make transmuting from fn item types to pointer-sized types a hard
+ error][34198]
