Rust 1.2 Brings Faster Compiler Performance, Parallel Code Generation
The Rust 1.2 release focuses on across-the-board compiler performance improvements and also now fully supports parallel code generation.
About the compiler performance improvements, "representative crates include hyper (compiles 1.16x faster), html5ever (1.62x faster), regex (1.32x faster) and rust-encoding (1.35x faster)."
Rust 1.2 also adds support for the Microsoft Visual C (MSVC) toolchain, the language work on dynamically-sized type (DST) is now complete, and other changes.
With the release of Rust 1.2 stable, Rust 1.3 went into beta and that release will bring a more efficient algorithm for its substring matcher, improvements to zero filling, and other enhancements.
More details on Rust 1.2 stable / Rust 1.3 beta can be found via the Rust-Lang.org blog.
