This time, +the fix is for when the `pattern` feature is enabled, which only works on +nightly Rust. CI has been updated to test this case. + +* [BUG #772](https://github.com/rust-lang/regex/pull/772): + Fix build when `pattern` feature is enabled. + + +1.5.3 (2021-05-01) +================== +This releases fixes a bug when building regex with only the `unicode-perl` +feature. It turns out that while CI was building this configuration, it wasn't +actually failing the overall build on a failed compilation. + +* [BUG #769](https://github.com/rust-lang/regex/issues/769): + Fix build in `regex-syntax` when only the `unicode-perl` feature is enabled. + + +1.5.2 (2021-05-01) +================== +This release fixes a performance bug when Unicode word boundaries are used. +Namely, for certain regexes on certain inputs, it's possible for the lazy DFA +to stop searching (causing a fallback to a slower engine) when it doesn't +actually need to. + +[PR #768](https://github.com/rust-lang/regex/pull/768) fixes the bug, which was +originally reported in +[ripgrep#1860](https://github.com/BurntSushi/ripgrep/issues/1860). + + +1.5.1 (2021-04-30) +================== +This is a patch release that fixes a compilation error when the `perf-literal` +feature is not enabled. + + +1.5.0 (2021-04-30) +================== +This release primarily updates to Rust 2018 (finally) and bumps the MSRV to +Rust 1.41 (from Rust 1.28). Rust 1.41 was chosen because it's still reasonably +old, and is what's in Debian stable at the time of writing. + +This release also drops this crate's own bespoke substring search algorithms +in favor of a new +[`memmem` implementation provided by the `memchr` crate](https://docs.rs/memchr/2.4.0/memchr/memmem/index.html). +This will change the performance profile of some regexes, sometimes getting a +little worse, and hopefully more frequently, getting a lot better. Please +report any serious performance regressions if you find them. + + +1.4.6 (2021-04-22) +================== +This is a small patch release that fixes the compiler's size check on how much +heap memory a regex uses. Previously, the compiler did not account for the +heap usage of Unicode character classes. Now it does. It's possible that this +may make some regexes fail to compile that previously did compile. If that +happens, please file an issue. + +* [BUG OSS-fuzz#33579](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=33579): + Some regexes can use more heap memory than one would expect. + + 1.4.5 (2021-03-14) ================== This is a small patch release that fixes a regression in the size of a `Regex` |
