Rollup merge of #29416 - brson:relnotes, r=alexcrichton
[Rendered](https://github.com/brson/rust/blob/relnotes/RELEASES.md) More highlights would be good. I intend to go through and hyperlink all the APIs still.

Version 1.4.0 (2015-10-29)
|
||||
============================
|
||||
|
||||
* ~1200 changes, numerous bugfixes
|
||||
|
||||
Highlights
|
||||
----------
|
||||
|
||||
* Windows builds targeting the 64-bit MSVC ABI and linker (instead of
|
||||
GNU) are now supported and recommended for use.
|
||||
|
||||
Breaking Changes
|
||||
----------------
|
||||
|
||||
* [Several changes have been made to fix type soundness and improve
|
||||
the behavior of associated types][sound]. See [RFC 1214]. Although
|
||||
we have mostly introduced these changes as warnings this release, to
|
||||
become errors next release, there are still some scenarios that will
|
||||
see immediate breakage.
|
||||
* [The `str::lines` and `BufRead::lines` iterators treat `\r\n` as
|
||||
line breaks in addition to `\n`][crlf].
|
||||
* [Loans of `'static` lifetime extend to the end of a function][stat].
|
||||
* [`str::parse` no longer introduces avoidable rounding error when
|
||||
parsing floating point numbers. Together with earlier changes to
|
||||
float formatting/output, "round trips" like f.to_string().parse()
|
||||
now preserve the value of f exactly. Additionally, leading plus
|
||||
signs are now accepted][fp3].
|
||||
|
||||
|
||||
Language
|
||||
--------
|
||||
|
||||
* `use` statements that import multiple items [can now rename
|
||||
them][i], as in `use foo::{bar as kitten, baz as puppy}`.
|
||||
* [Binops work correctly on fat pointers][binfat].
|
||||
* `pub extern crate`, which does not behave as expected, [issues a
|
||||
warning][pec] until a better solution is found.
|
||||
|
||||
Libraries
|
||||
---------
|
||||
|
||||
* [Many APIs were stabilized][stab]: `<Box<str>>::into_string`,
|
||||
[`Arc::downgrade`], [`Arc::get_mut`], [`Arc::make_mut`],
|
||||
[`Arc::try_unwrap`], [`Box::from_raw`], [`Box::into_raw`], [`CStr::to_str`],
|
||||
[`CStr::to_string_lossy`], [`CString::from_raw`], [`CString::into_raw`],
|
||||
[`IntoRawFd::into_raw_fd`], [`IntoRawFd`],
|
||||
`IntoRawHandle::into_raw_handle`, `IntoRawHandle`,
|
||||
`IntoRawSocket::into_raw_socket`, `IntoRawSocket`, [`Rc::downgrade`],
|
||||
[`Rc::get_mut`], [`Rc::make_mut`], [`Rc::try_unwrap`], [`Result::expect`],
|
||||
[`String::into_boxed_str`], [`TcpStream::read_timeout`],
|
||||
[`TcpStream::set_read_timeout`], [`TcpStream::set_write_timeout`],
|
||||
[`TcpStream::write_timeout`], [`UdpSocket::read_timeout`],
|
||||
[`UdpSocket::set_read_timeout`], [`UdpSocket::set_write_timeout`],
|
||||
[`UdpSocket::write_timeout`], `Vec::append`, `Vec::split_off`,
|
||||
[`VecDeque::append`], [`VecDeque::retain`], [`VecDeque::split_off`],
|
||||
[`rc::Weak::upgrade`], [`rc::Weak`], [`slice::Iter::as_slice`],
|
||||
[`slice::IterMut::into_slice`], [`str::CharIndices::as_str`],
|
||||
[`str::Chars::as_str`], [`str::split_at_mut`], [`str::split_at`],
|
||||
[`sync::Weak::upgrade`], [`sync::Weak`], [`thread::park_timeout`],
|
||||
[`thread::sleep`].
|
||||
* [Some APIs were deprecated][dep]: `BTreeMap::with_b`,
|
||||
`BTreeSet::with_b`, `Option::as_mut_slice`, `Option::as_slice`,
|
||||
`Result::as_mut_slice`, `Result::as_slice`, `f32::from_str_radix`,
|
||||
`f64::from_str_radix`.
|
||||
* [Reverse-searching strings is faster with the 'two-way'
|
||||
algorithm][s].
|
||||
* [`std::io::copy` allows `?Sized` arguments][cc].
|
||||
* The `Windows`, `Chunks`, and `ChunksMut` iterators over slices all
|
||||
[override `count`, `nth` and `last` with an O(1)
|
||||
implementation][it].
|
||||
* [`Default` is implemented for arrays up to `[T; 32]`][d].
|
||||
* [`IntoRawFd` has been added to the Unix-specific prelude,
|
||||
`IntoRawSocket` and `IntoRawHandle` to the Windows-specific
|
||||
prelude][pr].
|
||||
* [`Extend<String>` and `FromIterator<String` are both implemented for
|
||||
`String`][es].
|
||||
* [`IntoIterator` is implemented for references to `Option` and
|
||||
`Result`][into2].
|
||||
* [`HashMap` and `HashSet` implement `Extend<&T>` where `T:
|
||||
Copy`][ext] as part of [RFC 839]. This will cause type inferance
|
||||
breakage in rare situations.
|
||||
* [`BinaryHeap` implements `Debug`][bh2].
|
||||
* [`Borrow` and `BorrowMut` are implemented for fixed-size
|
||||
arrays][bm].
|
||||
* [`extern fn`s with the "Rust" and "C" ABIs implement common
|
||||
traits including `Eq`, `Ord`, `Debug`, `Hash`][fp].
|
||||
* [String comparison is faster][faststr].
|
||||
* `&mut T` where `T: std::fmt::Write` [also implements
|
||||
`std::fmt::Write`][mutw].
|
||||
* [A stable regression in `VecDeque::push_back` and other
|
||||
capicity-altering methods that caused panics for zero-sized types
|
||||
was fixed][vd].
|
||||
* [Function pointers implement traits for up to 12 parameters][fp2].
|
||||
|
||||
Miscellaneous
|
||||
-------------
|
||||
|
||||
* The compiler [no longer uses the 'morestack' feature to prevent
|
||||
stack overflow][mm]. Instead it uses guard pages and stack
|
||||
probes (though stack probes are not yet implemented on any platform
|
||||
but Windows).
|
||||
* [The compiler matches traits faster when projections are involved][p].
|
||||
* The 'improper_ctypes' lint [no longer warns about use of `isize` and
|
||||
`usize`][ffi].
|
||||
* [Cargo now displays useful information about what its doing during
|
||||
`cargo update`][cu].
