Rust

Rust comes as a suite of associated libraries, documentation files, and a full-on compiler.

The language itself was written specifically for developing client-server Web apps, with the main focus being on speed and a crash-free design.

Rust's syntax is very similar to C and C++, making it very easy to learn if you have basic programming knowledge.

Applications written in Rust are notably stable.

What is new in this release:

• The vast majority of the standard library is now #[stable]. It is no longer possible to use unstable features with a stable build of the compiler.
• Many popular crates on crates.io now work on the stable release channel.
• Arithmetic on basic integer types now checks for overflow in debug builds.

What is new in version 1.6.0:

• The vast majority of the standard library is now #[stable]. It is no longer possible to use unstable features with a stable build of the compiler.
• Many popular crates on crates.io now work on the stable release channel.
• Arithmetic on basic integer types now checks for overflow in debug builds.

What is new in version 1.5.0:

• The vast majority of the standard library is now #[stable]. It is no longer possible to use unstable features with a stable build of the compiler.
• Many popular crates on crates.io now work on the stable release channel.
• Arithmetic on basic integer types now checks for overflow in debug builds.

What is new in version 1.3.0:

• The vast majority of the standard library is now #[stable]. It is no longer possible to use unstable features with a stable build of the compiler.
• Many popular crates on crates.io now work on the stable release channel.
• Arithmetic on basic integer types now checks for overflow in debug builds.

What is new in version 1.0.0:

• The vast majority of the standard library is now #[stable]. It is no longer possible to use unstable features with a stable build of the compiler.
• Many popular crates on crates.io now work on the stable release channel.
• Arithmetic on basic integer types now checks for overflow in debug builds.

What is new in version 0.12.0 / 1.0.0-beta.4:

• The introductory documentation (now called The Rust Guide) has been completely rewritten, as have a number of supplementary guides.
• Rust's package manager, Cargo, continues to improve and is sometimes considered to be quite awesome.
• Many API's in std have been reviewed and updated for consistency with the in-development Rust coding guidelines. The standard library documentation tracks stabilization progress.
• Minor libraries have been moved out-of-tree to the rust-lang org on GitHub: uuid, semver, glob, num, hexfloat, fourcc. They can be installed with Cargo.
• Lifetime elision allows lifetime annotations to be left off of function declarations in many common scenarios.
• Rust now works on 64-bit Windows.

What is new in version 0.11.0:

• Struct fields are now all private by default.
• Vector indices and shift amounts are both required to be a `uint` now instead of any integral type.
• Byte character, byte string, and raw byte string literals are now all supported by prefixing the normal literal with a `b`.
• Multiple ABIs are no longer allowed in an ABI string
• The syntax for lifetimes on clousres/procedures has been tweaked slightly.
• Floating point modulus has been removed from the language, it is still provided by a library implementation, however.
• Private enum variants are now disallowed.
• The `priv` keyword has been removed from the language.
• A closure can no longer be invoked through a &-pointer.
• The `use foo, bar, baz;` syntax has been removed from the language.
• The transmute intrinsic no longer works on type parameters.
• Statics now allow blocks/items in their definition.
• Trait bounds are separated from objects with + instead of : now.
• Mutably borrowed objects can no longer be read while they are borrowed.

What is new in version 0.10:

• 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.

What is new in version 0.9:

• Made extensive improvements to the runtime and I/O subsystem.
• Introduced static linking and link-time optimization.
• Reduced the variety of closures in the language.

What is new in version 0.8:

• Strings no longer contain trailing nulls. The new `std::c_str` module provides new mechanisms for converting to C strings.
• The type of foreign functions is now `extern "C" fn` instead of `*u8'.
• The FFI has been overhauled such that foreign functions are called directly, instead of through a stack-switching wrapper.
• The `for` loop syntax has changed to work with the `Iterator` trait.
• At long last, unwinding works on Windows.
• Default methods are ready for use.
• Many trait inheritance bugs fixed.
• Owned and borrowed trait objects work more reliably.

What is new in version 0.6:

• Replaced the 'cargo' package manager with 'rustpkg'
• Added all-purpose 'rust' tool
• `rustc --test` now supports benchmarks with the `#[bench]` attribute
• rustc now *attempts* to offer spelling suggestions
• Improved support for ARM and Android
• Preliminary MIPS backend
• Improved foreign function ABI implementation for x86, x86_64
• Various memory usage improvements
• Rust code may be embedded in foreign code under limited circumstances

What is new in version 0.5:

• New condition handling system in `core::condition`
• Timsort added to `std::sort`
• New priority queue, `std::priority_queue`
• Pipes for serializable types, `std::flatpipes'
• Serialization overhauled to be trait-based
• Expanded `getopts` definitions
• Moved futures to `std`
