Version 0.6 (?)
---------------------------
* Libraries

Version 0.5 (December 2012)
---------------------------
* ~900 changes, numerous bugfixes
* Syntax changes
* Removed `<-` move operator
* Completed the transition from the `#fmt` extension syntax to `fmt!`
* Removed old fixed length vector syntax - `[T]/N`
* New token-based quasi-quoters, `quote_tokens!`, `quote_expr!`, etc.
* Macros may now expand to items and statements
* `a.b()` is always parsed as a method call, never as a field projection
* `Eq` and `IterBytes` implementations can be automatically generated
with `#[deriving_eq]` and `#[deriving_iter_bytes]` respectively
* Removed the special crate language for `.rc` files
* Function arguments may consist of any irrefutable pattern
* Semantic changes
* `&` and `~` pointers may point to objects
* Tuple structs - `struct Foo(Bar, Baz)`. Will replace newtype enums.
* Enum variants may be structs
* Destructors can be added to all nominal types with the Drop trait
* Structs and nullary enum variants may be constants
* Values that cannot be implicitly copied are now automatically moved
without writing `move` explicitly
* `&T` may now be coerced to `*T`
* Coercions happen in `let` statements as well as function calls
* `use` statements now take crate-relative paths
* The module and type namespaces have been merged so that static
method names can be resolved under the trait in which they are
declared
* Improved support for language features
* Trait inheritance works in many scenarios
* More support for explicit self arguments in methods - `self`, `&self`
`@self`, and `~self` all generally work as expected
* Static methods work in more situations
* Experimental: Traits may declare default methods for the implementations
to use
* Libraries
* 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`
* More functions are pure now
* `core::comm` renamed to `oldcomm`. Still deprecated
* `rustdoc` and `cargo` are libraries now
* Misc
* Added a preliminary REPL, `rusti`
* License changed from MIT to dual MIT/APL2
Version 0.4 (October 2012)
--------------------------
* ~2000 changes, numerous bugfixes
* Syntax
* All keywords are now strict and may not be used as identifiers anywhere
* Keyword removal: 'again', 'import', 'check', 'new', 'owned', 'send',
'of', 'with', 'to', 'class'.
* Classes are replaced with simpler structs
* Explicit method self types
* `ret` became `return` and `alt` became `match`
* `import` is now `use`; `use is now `extern mod`
* `extern mod { ... }` is now `extern { ... }`
* `use mod` is the recommended way to import modules
* `pub` and `priv` replace deprecated export lists
* The syntax of `match` pattern arms now uses fat arrow (=>)
* `main` no longer accepts an args vector; use `os::args` instead
* Semantics
* Trait implementations are now coherent, ala Haskell typeclasses
* Trait methods may be static
* Argument modes are deprecated
* Borrowed pointers are much more mature and recommended for use
* Strings and vectors in the static region are stored in constant memory
* Typestate was removed
* Resolution rewritten to be more reliable
* Support for 'dual-mode' data structures (freezing and thawing)
* Libraries
* Most binary operators can now be overloaded via the traits in
`core::ops'
* `std::net::url` for representing URLs
* Sendable hash maps in `core::send_map`
* `core::task' gained a (currently unsafe) task-local storage API
* Concurrency
* An efficient new intertask communication primitive called the pipe,
along with a number of higher-level channel types, in `core::pipes`
* `std::arc`, an atomically reference counted, immutable, shared memory
type
* `std::sync`, various exotic synchronization tools based on arcs and pipes
* Futures are now based on pipes and sendable
* More robust linked task failure
* Improved task builder API
* Other
* Improved error reporting
* Preliminary JIT support
* Preliminary work on precise GC
* Extensive architectural improvements to rustc
* Begun a transition away from buggy C++-based reflection (shape) code to
Rust-based (visitor) code
* All hash functions and tables converted to secure, randomized SipHash
Version 0.3 (July 2012)
------------------------
* ~1900 changes, numerous bugfixes
* New coding conveniences
* Integer-literal suffix inference
* Per-item control over warnings, errors
* #[cfg(windows)] and #[cfg(unix)] attributes
* Documentation comments
* More compact closure syntax
* 'do' expressions for treating higher-order functions as
control structures
* *-patterns (wildcard extended to all constructor fields)
* Semantic cleanup
* Name resolution pass and exhaustiveness checker rewritten
* Region pointers and borrow checking supersede alias
analysis
* Init-ness checking is now provided by a region-based liveness
pass instead of the typestate pass; same for last-use analysis
* Extensive work on region pointers
* Experimental new language features
* Slices and fixed-size, interior-allocated vectors
* #!-comments for lang versioning, shell execution
* Destructors and iface implementation for classes;
type-parameterized classes and class methods
* 'const' type kind for types that can be used to implement
shared-memory concurrency patterns
* Type reflection
* Removal of various obsolete features
* Keywords: 'be', 'prove', 'syntax', 'note', 'mutable', 'bind',
'crust', 'native' (now 'extern'), 'cont' (now 'again')
* Constructs: do-while loops ('do' repurposed), fn binding,
resources (replaced by destructors)
* Compiler reorganization
* Syntax-layer of compiler split into separate crate
* Clang (from LLVM project) integrated into build
* Typechecker split into sub-modules
* New library code
* New time functions
* Extension methods for many built-in types
* Arc: atomic-refcount read-only / exclusive-use shared cells
* Par: parallel map and search routines

#include, #include_str, #include_bin
