Release notes

Sourced from regex's releases.

1.0.0

This release marks the 1.0 release of regex.

While this release includes some breaking changes, most users of older versions of the regex library should be able to migrate to 1.0 by simply bumping the version number. The important changes are as follows:

• We adopt Rust 1.20 as the new minimum supported version of Rust for regex. We also tentativley adopt a policy that permits bumping the minimum supported version of Rust in minor version releases of regex, but no patch releases. That is, with respect to semver, we do not strictly consider bumping the minimum version of Rust to be a breaking change, but adopt a conservative stance as a compromise.
• Octal syntax in regular expressions has been disabled by default. This permits better error messages that inform users that backreferences aren't available. Octal syntax can be re-enabled via the corresponding option on RegexBuilder.
• (?-u:\B) is no longer allowed in Unicode regexes since it can match at invalid UTF-8 code unit boundaries. (?-u:\b) is still allowed in Unicode regexes.
• The From<regex_syntax::Error> impl has been removed. This formally removes the public dependency on regex-syntax.
• A new feature, use_std, has been added and enabled by default. Disabling the feature will result in a compilation error. In the future, this may permit us to support no_std environments (w/ alloc) in a backwards compatible way.

For more information and discussion, please see 1.0 release tracking issue.

0.2.7

This release includes a ground-up rewrite of the regex-syntax crate, which has been in development for over a year.

New features:

• Error messages for invalid regexes have been greatly improved. You get these automatically; you don't need to do anything. In addition to better formatting, error messages will now explicitly call out the use of look around. When regex 1.0 is released, this will happen for backreferences as well.
• Full support for intersection, difference and symmetric difference of character classes. These can be used via the &&, -- and ~~ binary operators within classes.
• A Unicode Level 1 conformat implementation of \p{..} character classes. Things like \p{scx:Hira}, \p{age:3.2} or \p{Changes_When_Casefolded} now work. All property name and value aliases are supported, and properties are selected via loose matching. e.g., \p{Greek} is the same as \p{G r E e K}.
• A new UNICODE.md document has been added to this repository that

Changelog

Sourced from regex's changelog.

1.5.4 (2021-05-06)

This release fixes another compilation failure when building regex. 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](rust-lang/regex#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](rust-lang/regex#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](rust-lang/regex#768) fixes the bug, which was originally reported in ripgrep#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. 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.
