regex v0.2.9 Release Notes

Release Date: 2018-03-12 // about 6 years ago

  • 🚀 This release introduces a new nightly only feature, unstable, which enables SIMD optimizations for certain types of regexes. No additional compile time options are necessary, and the regex crate will automatically choose the best CPU features at run time. As a result, the simd (nightly only) crate dependency has been dropped.

    🆕 New features:

    • FEATURE #456: The regex crate now includes AVX2 optimizations in addition to the extant SSSE3 optimization.

    🐛 Bug fixes:

    • BUG #455: Fix a bug where (?x)[ / - ] failed to parse.
