The gear keeps turning: we're releasing Rust 1.3 stable today! As always, read on for the highlights and check the release notes for more detail.
This is our first release shipping with the Rustonomicon, a new book covering "The Dark Arts of Advanced and Unsafe Rust Programming". While it's still in draft form, this book already provides deep coverage of some of Rust's darker corners.
On the library front, we saw a fair amount of API stabilization, including the
new Duration API and enhancements to Error and Hash/Hasher. We expect to
see further growth of the std::time module in the 1.5 timeframe.
The 1.3 cycle also saw continuing focus on performance. Most wins here are within the standard library:
Vec::resize and Read::read_to_end.Read::read_to_end has been
specialized for stdin and File,
resulting in additional speedups.PartialEq implementation on slices is now
much faster.We're continuing to invest in Windows, with preliminary support for targeting Windows XP. While we do not intend to treat Windows XP as a "first tier" platform, it is now feasible to build Rust code for XP as long as you avoid certain parts of the standard library. Work on MSVC toolchain integration is ongoing, with full support (on 64-bit) shipping in the 1.4 beta today.
On the Cargo front, we have landed support for lint capping as specified by an earlier RFC. The idea is that lints in your dependencies should not affect your ability to compile cleanly, which in turn makes it easier to tweak the way lints work without undue hassle in the ecosystem.
Rust is a community-driven language, and we're delighted to thank the 131 contributors to this release:
