Version 0.4 (September 2012)
* ~1500 changes
* 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
* Method self types
* `ret` became `return` and `alt` became `match`
* Semantics
* Trait implementations are now coherent, ala Haskell typeclasses
* 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 is rewritten to be more reliable
* Support for 'dual-mode' data structures (freezing and thawing)
* Last-use analysis is only used for warnings now. Moves must be explicit
for lvalues (TODO: confirm)
* 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 very unsafe) task-local storage API
* Concurrency
* An effecient new intertask communication primitive called `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
* Hash functions improved across the codebase (TODO: need details)
* New lint checks (TODO: which?)

2012-07-11 02:06:58 +00:00
'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
