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:
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
in the 1.4.4 release. Prior to 1.4.4, a Regex was 552 bytes. In the 1.4.4
release, it was 856 bytes due to internal changes. In this release, a Regex
is now 16 bytes. In general, the size of a Regex was never something that was
on my radar, but this increased size in the 1.4.4 release seems to have crossed
a threshold and resulted in stack overflows in some programs.
[BUG #750](rust-lang/regex#750):
Fixes stack overflows seemingly caused by a large Regex size by decreasing
its size.
1.4.4 (2021-03-11)
This is a small patch release that contains some bug fixes. Notably, it also
drops the thread_local (and lazy_static, via transitivity) dependencies.
Bug fixes:
[BUG #362](rust-lang/regex#362):
Memory leaks caused by an internal caching strategy should now be fixed.
[BUG #576](rust-lang/regex#576):
All regex types now implement UnwindSafe and RefUnwindSafe.
