Release Notes

rust-lang/regex (regex)

v1.12.1

Compare Source

===================
This release makes a bug fix in the new regex::Captures::get_match API
introduced in 1.12.0. There was an oversight with the lifetime parameter
for the Match returned. This is technically a breaking change, but given
that it was caught almost immediately and I've yanked the 1.12.0 release,
I think this is fine.

v1.12.0

consumption in some cases and a new regex::Captures::get_match API.
