160 1.4.5 (2021-03-14)
162 This is a small patch release that fixes a regression in the size of a `Regex`
163 in the 1.4.4 release. Prior to 1.4.4, a `Regex` was 552 bytes. In the 1.4.4
164 release, it was 856 bytes due to internal changes. In this release, a `Regex`
165 is now 16 bytes. In general, the size of a `Regex` was never something that was
166 on my radar, but this increased size in the 1.4.4 release seems to have crossed

356 1.3.1 (2019-09-04)
358 This is a maintenance release with no changes in order to try to work-around
359 a [docs.rs/Cargo issue](https://github.com/rust-lang/docs.rs/issues/400).
362 1.3.0 (2019-09-03)
364 This release adds a plethora of new crate features that permit users of regex
365 to shrink its size considerably, in exchange for giving up either functionality
367 disabled, the dependency tree for `regex` shrinks to exactly 1 crate
368 (`regex-syntax`). More information about the new crate features can be
369 [found in the docs](https://docs.rs/regex/*/#crate-features).
376 * [FEATURE #474](https://github.com/rust-lang/regex/issues/474):

381 Add a substantial number of crate features shrinking `regex`.
384 1.2.1 (2019-08-03)
391 * Teddy has been removed from the `regex` crate, and is now part of the
392 `aho-corasick` crate.
393 …[See `aho-corasick`'s new `packed` sub-module for details](https://docs.rs/aho-corasick/0.7.6/aho_…
394 * The `utf8-ranges` crate has been deprecated, with its functionality moving
396 …[`utf8` sub-module of `regex-syntax`](https://docs.rs/regex-syntax/0.6.11/regex_syntax/utf8/index.…
397 * The `ucd-util` dependency has been dropped, in favor of implementing what
398 little we need inside of `regex-syntax` itself.
400 In general, this is part of an ongoing (long term) effort to make optimizations
401 in the regex engine easier to reason about. The current code is too convoluted
402 and thus it is very easy to introduce new bugs. This simplification effort is
403 the primary motivation behind re-working the `aho-corasick` crate to not only
404 bundle algorithms like Teddy, but to also provide regex-like match semantics
407 Moving forward, the plan is to join up with the `bstr` and `regex-automata`
409 algorithms (thereby deleting existing code in `regex`) and the latter providing
410 ahead-of-time compiled DFAs for cases where they are inexpensive to compute.
413 1.2.0 (2019-07-20)
415 This release updates regex's minimum supported Rust version to 1.28, which was

417 tables to 12.1.0.

890 Compiling `regex` should only require one version of `memchr` crate.
895 This is a new major release of the regex crate, and is an implementation of the
896 [regex 1.0 RFC](https://github.com/rust-lang/rfcs/blob/master/text/1620-regex-1.0.md).
902 types. The first type correspond to breaking changes in regular expression
903 syntax. The second type correspond to breaking changes in the API.
905 Breaking changes for regex syntax:
907 * POSIX character classes now require double bracketing. Previously, the regex
909 as the character class containing the characters `:upper:`. The fix to this
910 change is to use `[[:upper:]]` instead. Note that variants like
911 `[[:upper:][:blank:]]` continue to work.
913 * The characters `&`, `-` and `~` must be escaped if any one of them are
914 repeated consecutively. For example, `[&]`, `[\&]`, `[\&\&]`, `[&-&]` are all
916 change is to provide a backwards compatible path for adding character class
918 * A `bytes::Regex` now has Unicode mode enabled by default (like the main
919 `Regex` type). This means regexes compiled with `bytes::Regex::new` that
920 don't have the Unicode flag set should add `(?-u)` to recover the original
923 Breaking changes for the regex API:
931 `iter_named` should use the `capture_names` method on `Regex`.
932 * The `at` method on the `Captures` type has been renamed to `get`, and it
939 the `replace` methods should continue to work unchanged. If you implement
941 * The `quote` free function has been renamed to `escape`.
942 * The `Regex::with_size_limit` method has been removed. It is replaced by
944 * The `RegexBuilder` type has switched from owned `self` method receivers to
945 `&mut self` method receivers. Most uses will continue to work unchanged, but
946 some code may require naming an intermediate variable to hold the builder.
947 * The `compile` method on `RegexBuilder` has been renamed to `build`.
949 a `Regex` and calling its `is_match` method.
950 * The `PartialEq` and `Eq` impls on `Regex` have been dropped. If you relied
951 on these impls, the fix is to define a wrapper type around `Regex`, impl
957 you'll need to explicitly use the `regex_syntax` crate to re-parse the regex.
960 * Most of the iterator types have been renamed to match conventions. If you
962 for its new name. For example, `RegexSplits` has been renamed to `Split`.
