Mozilla and the Rust community are pleased to announce version 0.10 of the
Rust compiler and tools. Rust is a systems programming language with a
focus on safety, performance and concurrency.
This was an exciting release cycle where we broke apart the libextra
library, introduced cross-crate syntax extensions and macros, improved the smart
pointer experience with the Deref trait, and improved error handling in I/O.
Outside of the compiler, this release has seen the introduction of a new RFC
process as well as support for nightly binary installers.
The brief release notes are included in this announcement, and there is
further explanation in the detailed release [notes] on the wiki.
Documentation and all the links in this email are available on the
[website]. As usual, version 0.10 should be considered an alpha release,
suitable for early adopters and language enthusiasts. Please file [bugs]
and join the [fun].

Version 0.10 (April 2014)
-------------------------
* ~1500 changes, numerous bugfixes
* Language
* A new RFC process is now in place for modifying the language.
* Patterns with `@`-pointers have been removed from the language.
* Patterns with unique vectors (`~[T]`) have been removed from the
language.
* Patterns with unique strings (`~str`) have been removed from the
language.
* `@str` has been removed from the language.
* `@[T]` has been removed from the language.
* `@self` has been removed from the language.
* `@Trait` has been removed from the language.
* Headers on `~` allocations which contain `@` boxes inside the type for
reference counting have been removed.
* The semantics around the lifetimes of temporary expressions have changed,
see #3511 and #11585 for more information.
* Cross-crate syntax extensions are now possible, but feature gated. See
#11151 for more information. This includes both `macro_rules!` macros as
well as syntax extensions such as `format!`.
* New lint modes have been added, and older ones have been turned on to be
warn-by-default.
* Unnecessary parentheses
* Uppercase statics
* Camel Case types
* Uppercase variables
* Publicly visible private types
* `#[deriving]` with raw pointers
* Unsafe functions can no longer be coerced to closures.
* Various obscure macros such as `log_syntax!` are now behind feature gates.
* The `#[simd]` attribute is now behind a feature gate.
* Visibility is no longer allowed on `extern crate` statements, and
unnecessary visibility (`priv`) is no longer allowed on `use` statements.
* Trailing commas are now allowed in argument lists and tuple patterns.
* The `do` keyword has been removed, it is now a reserved keyword.
* Default type parameters have been implemented, but are feature gated.
* Borrowed variables through captures in closures are now
considered soundly.
* `extern mod` is now `extern crate`
* The `Freeze` trait has been removed.
* The `Share` trait has been added for types that can be shared among
threads.
* Labels in macros are now hygienic.
* Expression/statement macro invocations can be delimited with `{}` now.
* Treatment of types allowed in `static mut` locations has been tweaked.
* The `*` and `.` operators are now overloadable through the `Deref` and
`DerefMut` traits.
* `~Trait` and `proc` no longer have `Send` bounds by default.
* Partial type hints are now supported with the `_` type marker.
* An `Unsafe` type was introduced for interior mutability. It is now
considered undefined to transmute from `&T` to `&mut T` without using the
`Unsafe` type.
* The #[linkage] attribute was implemented for extern statics/functions.
* The inner attribute syntax has changed from `#[foo];` to `#![foo]`.
* `Pod` was renamed to `Copy`.
* Libraries
* The `libextra` library has been removed. It has now been decomposed into
component libraries with smaller and more focused nuggets of
functionality. The full list of libraries can be found on the
documentation index page.
* std: `std::condition` has been removed. All I/O errors are now propagated
through the `Result` type. In order to assist with error handling, a
`try!` macro for unwrapping errors with an early return and an lint for
unused results has been added. See #12039 for more information.
* std: The `vec` module has been renamed to `slice`.
* std: A new vector type, `Vec<T>`, has been added in preparation for DST.
This will become the only growable vector in the future.
* std: `std::io` now has more public-reexports. Types such as
`BufferedReader`
are now found at `std::io::BufferedReader` instead of
`std::io::buffered::BufferedReader`.
* std: `print` and `println` are no longer in the prelude, the `print!` and
`println!` macros are intended to be used instead.
* std: `Rc` now has a `Weak` pointer for breaking cycles, and it no longer
attempts to statically prevent cycles.
* std: The standard distribution is adopting the policy of pushing failure
to the user rather than failing in libraries. Many functions (such as
`slice::last()`) now return `Option<T>` instead of `T` + failing.
* std: `fmt::Default` has been renamed to `fmt::Show`, and it now has a new
deriving mode: `#[deriving(Show)]`.
* std: `ToStr` is now implemented for all types implementing `Show`.
* std: The formatting trait methods now take `&self` instead of `&T`
* std: The `invert()` method on iterators has been renamed to `rev()`
* std: `std::num` has seen a reduction in the genericity of its traits,
consolidating functionality into a few core traits.
* std: Backtraces are now printed on task failure if the environment
variable `RUST_BACKTRACE` is present.
* std: Naming conventions for iterators have been standardized. More details
can be found on the wiki's style guide.
* std: `eof()` has been removed from the `Reader` trait. Specific types may
still implement the function.
* std: Networking types are now cloneable to allow simultaneous
reads/writes.
* std: `assert_approx_eq!` has been removed
* std: The `e` and `E` formatting specifiers for floats have been added to
print them in exponential notation.
* std: The `Times` trait has been removed
* std: Indications of variance and opting out of builtin bounds is done
through marker types in `std::kinds::marker` now
* std: `hash` has been rewritten, `IterBytes` has been removed, and
`#[deriving(Hash)]` is now possible.
* std: `SharedChan` has been removed, `Sender` is now cloneable.
* std: `Chan` and `Port` were renamed to `Sender` and `Receiver`.
* std: `Chan::new` is now `channel()`.
* std: A new synchronous channel type has been implemented.
* std: A `select!` macro is now provided for selecting over `Receiver`s.
* std: `hashmap` and `trie` have been moved to `libcollections`
* std: `run` has been rolled into `io::process`
* std: `assert_eq!` now uses `{}` instead of `{:?}`
* std: The equality and comparison traits have seen some reorganization.
* std: `rand` has moved to `librand`.
* std: `to_{lower,upper}case` has been implemented for `char`.
* std: Logging has been moved to `liblog`.
* collections: `HashMap` has been rewritten for higher performance and less
memory usage.
* native: The default runtime is now `libnative`. If `libgreen` is desired,
it can be booted manually. The runtime guide has more information and
examples.
* native: All I/O functionality except signals has been implemented.
* green: Task spawning with `libgreen` has been optimized with stack caching
and various trimming of code.
* green: Tasks spawned by `libgreen` now have an unmapped guard page.
* sync: The `extra::sync` module has been updated to modern rust (and moved
to the `sync` library), tweaking and improving various interfaces while
dropping redundant functionality.
* sync: A new `Barrier` type has been added to the `sync` library.
* sync: An efficient mutex for native and green tasks has been implemented.
* serialize: The `base64` module has seen some improvement. It treats
newlines better, has non-string error values, and has seen general
cleanup.
* fourcc: A `fourcc!` macro was introduced
* hexfloat: A `hexfloat!` macro was implemented for specifying floats via a
hexadecimal literal.
* Tooling
* `rustpkg` has been deprecated and removed from the main repository. Its
replacement, `cargo`, is under development.
* Nightly builds of rust are now available
* The memory usage of rustc has been improved many times throughout this
release cycle.
* The build process supports disabling rpath support for the rustc binary
itself.
* Code generation has improved in some cases, giving more information to the
LLVM optimization passes to enable more extensive optimizations.
* Debuginfo compatibility with lldb on OSX has been restored.
* The master branch is now gated on an android bot, making building for
android much more reliable.
* Output flags have been centralized into one `--emit` flag.
* Crate type flags have been centralized into one `--crate-type` flag.
* Codegen flags have been consolidated behind a `-C` flag.
* Linking against outdated crates now has improved error messages.
* Error messages with lifetimes will often suggest how to annotate the
function to fix the error.
* Many more types are documented in the standard library, and new guides
were written.
* Many `rustdoc` improvements:
* code blocks are syntax highlighted.
* render standalone markdown files.
* the --test flag tests all code blocks by default.
* exported macros are displayed.
* reexported types have their documentation inlined at the location of the
first reexport.
* search works across crates that have been rendered to the same output
directory.
