This releases fixes a security bug in the regex compiler. This bug permits a
vector for a denial-of-service attack in cases where the regex being compiled
is untrusted. There are no known problems where the regex is itself trusted,
including in cases of untrusted haystacks.
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.
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.
