Version 1.0.0-alpha.2 (February 2015)
-------------------------------------
* ~1300 changes, numerous bugfixes
* Highlights
* The various I/O modules were [overhauled][io-rfc] to reduce
unncessary abstractions and provide better interoperation with
the underlying platform. The old `io` module remains temporarily
at `std::old_io`.
* The standard library now [partipates in feature gating][feat],
so use of unstable libraries now requires a `#![feature(...)]`
attribute. The impact of this change is [described on the
forum][feat-forum]. [RFC][feat-rfc].
* Language
* `for` loops [now operate on the `IntoIterator` trait][into],
which eliminates the need to call `.iter()`, etc. to iterate
over collections. There are some new subtleties to remember
though regarding what sort of iterators various types yield, in
particular that `for foo in bar { }` yields values from a move
iterator, destroying the original collection. [RFC][into-rfc].
* Objects now have [default lifetime bounds][obj], so you don't
have to write `Box<Trait+'static>` when you don't care about
storing references. [RFC][obj-rfc].
* In types that implement `Drop`, [lifetimes must outlive the
value][drop]. This will soon make it possible to safely
implement `Drop` for types where `#[unsafe_destructor]` is now
required. Read the [gorgeous RFC][drop-rfc] for details.
* The fully qualified <T as Trait>::X syntax lets you set the Self
type for a trait method or associated type. [RFC][ufcs-rfc].
* References to types that implement `Deref<U>` now [automatically
coerce to references][deref] to the dereferenced type `U`,
e.g. `&T where T: Deref<U>` automatically coerces to `&U`. This
should eliminate many unsightly uses of `&*`, as when converting
from references to vectors into references to
slices. [RFC][deref-rfc].
* The explicit [closure kind syntax][close] (`|&:|`, `|&mut:|`,
`|:|`) is obsolete and closure kind is inferred from context.
* [`Self` is a keyword][Self].
* Libraries
* The `Show` and `String` formatting traits [have been
renamed][fmt] to `Debug` and `Display` to more clearly reflect
their related purposes. Automatically getting a string
conversion to use with `format!("{:?}", something_to_debug)` is
now written `#[derive(Debug)]`.
* Abstract [OS-specific string types][osstr], `std::ff::{OsString,
OsStr}`, provide strings in platform-specific encodings for easier
interop with system APIs. [RFC][osstr-rfc].
* The `boxed::into_raw` and `Box::frow_raw` functions [convert
between `Box<T>` and `*mut T`][boxraw], a common pattern for
creating raw pointers.
* Tooling
* Certain long error messages of the form 'expected foo found bar'
are now [split neatly across multiple
lines][multiline]. Examples in the PR.
* On Unix Rust can be [uninstalled][un] by running
`/usr/local/lib/rustlib/uninstall.sh`.
* The `#[rustc_on_unimplemented]` attribute, requiring the
'on_unimplemented' feature, lets rustc [display custom error
messages when a trait is expected to be implemented for a type
but is not][onun].
* Misc
* Rust is tested against a [LALR grammar][lalr], which parses
almost all the Rust files that rustc does.
