* ~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 * Extensive work on libuv interface * Much vector code moved to libraries * Syntax extensions: #line, #col, #file, #mod, #stringify, #include, #include_str, #include_bin * Tool improvements * Cargo automatically resolves dependencies
