+Version 1.1.0 (June 2015)
+=========================
-* NNNN changes, numerous bugfixes
+* ~850 changes, numerous bugfixes
-Libraries
----------
+Highlights
+----------
* The [`std::fs` module has been expanded][fs-expand] to expand the set of
functionality exposed:
* A `symlink_metadata` function has been added.
* The `fs::Metadata` structure now lowers to its OS counterpart, providing
access to all underlying information.
+* The compiler contains extended explanations of many errors. When it
+ emits such an error it also suggests using the `--explain` flag to
+ read the extended explanations, which are also [cataloged on the web
+ site][err].
+* Thanks to multiple [improvements][sk] to [type checking][pre], as
+ well as other work, the time to bootstrap the compiler decreased by
+ 32%.
+
+Libraries
+---------
+
+* The `str::split_whitespace` method splits a string on unicode
+ whitespace boundaries.
+* On both Windows and Unix, new extension traits provide conversion of
+ I/O types to and from the underlying system handles. On Unix, these
+ traits are [`FrowRawFd`] and [`AsRawFd`], on Windows `FromRawHandle`
+ and `AsRawHandle`. These are implemented for `File`, `TcpStream`,
+ `TcpListener`, and `UpdSocket`. Further implementations for
+ `std::process` will be stabilized later.
+* On Unix, [`std::os::unix::symlink`] creates symlinks. On
+ Windows, symlinks can be created with
+ `std::os::windows::symlink_dir` and
+ `std::os::windows::symlink_file`.
+* The `mpsc::Receiver` type can now be converted into an iterator with
+ `into_iter` on the [`IntoIterator`] trait.
+* `Ipv4Addr` can be created from `u32` with the `From<u32>`
+ implementation of the [`From`] trait.
+* The `Debug` implementation for `RangeFull` [creates output that is
+ more consistent with other implementations][rf].
+* [`Debug` is implemented for `File`][file].
+* The `Default` implementation for `Arc` [no longer requires `Sync +
+ Send`][arc].
+* [The `Iterator` methods `count`, `nth`, and `last` have been
+ overridden for slices to have O(1) performance instead of O(n)][si].
+* Incorrect handling of paths on Windows has been improved in both the
+ compiler and the standard library.
+* [`AtomicPtr` gained a `Default` implementation][ap].
+* In accordance with Rust's policy on arithmetic overflow `abs` now
+ [panics on overflow when debug assertions are enabled][abs].
+* The [`Cloned`] iterator, which was accidentally left unstable for
+ 1.0 [has been stabilized][c].
+* The [`Incoming`] iterator, which iterates over incoming TCP
+ connections, and which was accidentally unnamable in 1.0, [is now
+ properly exported][inc].
+* [`BinaryHeap`] no longer corrupts itself [when functions called by
+ `sift_up` or `sift_down` panic][bh].
+* The [`split_off`] method of `LinkedList` [no longer corrupts
+ the list in certain scenarios][ll].

+* Type checking performance [has improved notably][sk] with
+ [multiple improvements][pre].
+* The compiler [suggests code changes][ch] for more errors.
+* rustc and it's build system have experimental support for [building
+ toolchains against MUSL][m] instead of glibc on Linux.
+* The compiler defines the `target_env` cfg value, which is used for
+ distinguishing toolchains that are otherwise for the same
+ platform. Presently this is set to `gnu` for common GNU Linux
+ targets and for MinGW targets, and `musl` for MUSL Linux targets.
+* The [`cargo rustc`][crc] command invokes a build with custom flags
+ to rustc.
+* [Android executables are always position independent][pie].
+* [The `drop_with_repr_extern` lint warns about mixing `repr(C)`
+ with `Drop`][drop].
