### [`v1.9.4`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#194-2023-08-26)
[Compare Source](https://togithub.com/rust-lang/regex/compare/1.9.3...1.9.4)
\==================
This is a patch release that fixes a bug where `RegexSet::is_match(..)` could
incorrectly return false (even when `RegexSet::matches(..).matched_any()`
returns true).
Bug fixes:
- [BUG #1070](https://togithub.com/rust-lang/regex/issues/1070):
Fix a bug where a prefilter was incorrectly configured for a `RegexSet`.
### [`v1.9.3`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#193-2023-08-05)
[Compare Source](https://togithub.com/rust-lang/regex/compare/1.9.2...1.9.3)
\==================
This is a patch release that fixes a bug where some searches could result in
incorrect match offsets being reported. It is difficult to characterize the
types of regexes susceptible to this bug. They generally involve patterns
that contain no prefix or suffix literals, but have an inner literal along with
a regex prefix that can conditionally match.
Bug fixes:
- [BUG #1060](https://togithub.com/rust-lang/regex/issues/1060):
Fix a bug with the reverse inner literal optimization reporting incorrect match
offsets.
### [`v1.9.2`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#192-2023-08-05)
[Compare Source](https://togithub.com/rust-lang/regex/compare/1.9.1...1.9.2)
\==================
This is a patch release that fixes another memory usage regression. This
particular regression occurred only when using a `RegexSet`. In some cases,
much more heap memory (by one or two orders of magnitude) was allocated than in
versions prior to 1.9.0.
Bug fixes:
- [BUG #1059](https://togithub.com/rust-lang/regex/issues/1059):
Fix a memory usage regression when using a `RegexSet`.
### [`v1.9.1`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#191-2023-07-07)
[Compare Source](https://togithub.com/rust-lang/regex/compare/1.9.0...1.9.1)
\==================
This is a patch release which fixes a memory usage regression. In the regex
1.9 release, one of the internal engines used a more aggressive allocation
strategy than what was done previously. This patch release reverts to the
prior on-demand strategy.
Bug fixes:
- [BUG #1027](https://togithub.com/rust-lang/regex/issues/1027):
Change the allocation strategy for the backtracker to be less aggressive.
### [`v1.9.0`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#190-2023-07-05)
[Compare Source](https://togithub.com/rust-lang/regex/compare/1.8.4...1.9.0)
\==================
This release marks the end of a [years long rewrite of the regex crate
internals](https://togithub.com/rust-lang/regex/issues/656). Since this is
such a big release, please report any issues or regressions you find. We would
also love to hear about improvements as well.
In addition to many internal improvements that should hopefully result in
"my regex searches are faster," there have also been a few API additions:
- A new `Captures::extract` method for quickly accessing the substrings
that match each capture group in a regex.
- A new inline flag, `R`, which enables CRLF mode. This makes `.` match any
Unicode scalar value except for `\r` and `\n`, and also makes `(?m:^)` and
`(?m:$)` match after and before both `\r` and `\n`, respectively, but never
between a `\r` and `\n`.
- `RegexBuilder::line_terminator` was added to further customize the line
terminator used by `(?m:^)` and `(?m:$)` to be any arbitrary byte.
- The `std` Cargo feature is now actually optional. That is, the `regex` crate
can be used without the standard library.
- Because `regex 1.9` may make binary size and compile times even worse, a
new experimental crate called `regex-lite` has been published. It prioritizes
binary size and compile times over functionality (like Unicode) and
performance. It shares no code with the `regex` crate.
New features:
- [FEATURE #244](https://togithub.com/rust-lang/regex/issues/244):
One can opt into CRLF mode via the `R` flag.
e.g., `(?mR:$)` matches just before `\r\n`.
- [FEATURE #259](https://togithub.com/rust-lang/regex/issues/259):
Multi-pattern searches with offsets can be done with `regex-automata 0.3`.
- [FEATURE #476](https://togithub.com/rust-lang/regex/issues/476):
`std` is now an optional feature. `regex` may be used with only `alloc`.
- [FEATURE #644](https://togithub.com/rust-lang/regex/issues/644):
`RegexBuilder::line_terminator` configures how `(?m:^)` and `(?m:$)` behave.
- [FEATURE #675](https://togithub.com/rust-lang/regex/issues/675):
Anchored search APIs are now available in `regex-automata 0.3`.
- [FEATURE #824](https://togithub.com/rust-lang/regex/issues/824):
Add new `Captures::extract` method for easier capture group access.
- [FEATURE #961](https://togithub.com/rust-lang/regex/issues/961):
Add `regex-lite` crate with smaller binary sizes and faster compile times.
- [FEATURE #1022](https://togithub.com/rust-lang/regex/pull/1022):
Add `TryFrom` implementations for the `Regex` type.
Performance improvements:
- [PERF #68](https://togithub.com/rust-lang/regex/issues/68):
Added a one-pass DFA engine for faster capture group matching.
- [PERF #510](https://togithub.com/rust-lang/regex/issues/510):
Inner literals are now used to accelerate searches, e.g., `\w+@\w+` will scan
for `@`.
- [PERF #787](https://togithub.com/rust-lang/regex/issues/787),
[PERF #891](https://togithub.com/rust-lang/regex/issues/891):
Makes literal optimizations apply to regexes of the form `\b(foo|bar|quux)\b`.
(There are many more performance improvements as well, but not all of them have
specific issues devoted to them.)
Bug fixes:
- [BUG #429](https://togithub.com/rust-lang/regex/issues/429):
Fix matching bugs related to `\B` and inconsistencies across internal engines.
- [BUG #517](https://togithub.com/rust-lang/regex/issues/517):
Fix matching bug with capture groups.
- [BUG #579](https://togithub.com/rust-lang/regex/issues/579):
Fix matching bug with word boundaries.
- [BUG #779](https://togithub.com/rust-lang/regex/issues/779):
Fix bug where some regexes like `(re)+` were not equivalent to `(re)(re)*`.
- [BUG #850](https://togithub.com/rust-lang/regex/issues/850):
Fix matching bug inconsistency between NFA and DFA engines.
- [BUG #921](https://togithub.com/rust-lang/regex/issues/921):
Fix matching bug where literal extraction got confused by `$`.
- [BUG #976](https://togithub.com/rust-lang/regex/issues/976):
Add documentation to replacement routines about dealing with fallibility.
- [BUG #1002](https://togithub.com/rust-lang/regex/issues/1002):
Use corpus rejection in fuzz testing.
### [`v1.8.4`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#184-2023-06-05)
[Compare Source](https://togithub.com/rust-lang/regex/compare/1.8.3...1.8.4)
\==================
This is a patch release that fixes a bug where `(?-u:\B)` was allowed in
Unicode regexes, despite the fact that the current matching engines can report
match offsets between the code units of a single UTF-8 encoded codepoint. That
in turn means that match offsets that split a codepoint could be reported,
which in turn results in panicking when one uses them to slice a `&str`.
This bug occurred in the transition to `regex 1.8` because the underlying
syntactical error that prevented this regex from compiling was intentionally
removed. That's because `(?-u:\B)` will be permitted in Unicode regexes in
`regex 1.9`, but the matching engines will guarantee to never report match
offsets that split a codepoint. When the underlying syntactical error was
removed, no code was added to ensure that `(?-u:\B)` didn't compile in the
`regex 1.8` transition release. This release, `regex 1.8.4`, adds that code
such that `Regex::new(r"(?-u:\B)")` returns to the `regex <1.8` behavior of
not compiling. (A `bytes::Regex` can still of course compile it.)
Bug fixes:
- [BUG #1006](https://togithub.com/rust-lang/regex/issues/1006):
Fix a bug where `(?-u:\B)` was allowed in Unicode regexes, and in turn could
lead to match offsets that split a codepoint in `&str`.
