1.10.1 (2023-10-14)

This is a new patch release with a minor increase in the number of valid patterns and a broadening of some literal optimizations.

New features:

• FEATURE 04f5d7be: Loosen ASCII-compatible rules such that regexes like (?-u:☃) are now allowed.

Performance improvements:

• PERF 8a8d599f: Broader the reverse suffix optimization to apply in more cases.

1.10.0 (2023-10-09)

This is a new minor release of regex that adds support for start and end word boundary assertions. That is, \< and \>. The minimum supported Rust version has also been raised to 1.65, which was released about one year ago.

The new word boundary assertions are:

• \< or \b{start}: a Unicode start-of-word boundary (\W|\A on the left, \w on the right).
• \> or \b{end}: a Unicode end-of-word boundary (\w on the left, \W|\z on the right)).
• \b{start-half}: half of a Unicode start-of-word boundary (\W|\A on the left).
• \b{end-half}: half of a Unicode end-of-word boundary (\W|\z on the right).

The \< and \> are GNU extensions to POSIX regexes. They have been added to the regex crate because they enjoy somewhat broad support in other regex engines as well (for example, vim). The \b{start} and \b{end} assertions are aliases for \< and \>, respectively.

The \b{start-half} and \b{end-half} assertions are not found in any other regex engine (although regex engines with general look-around support can certainly express them). They were added principally to support the implementation of word matching in grep programs, where one generally wants to be a bit more flexible in what is considered a word boundary.

New features:

• [FEATURE #469](rust-lang/regex#469): Add support for \< and \> word boundary assertions.
• [FEATURE(regex-automata) #1031](rust-lang/regex#1031): DFAs now have a start_state method that doesn't use an Input.
