<blockquote>
<h1>1.12.2 (2025-10-13)</h1>
<p>This release fixes a <code>cargo doc</code> breakage on nightly when
<code>--cfg docsrs</code> is
enabled. This caused documentation to fail to build on docs.rs.</p>
<p>Bug fixes:</p>
<ul>
<li>[BUG <a
href="https://redirect.github.com/rust-lang/regex/issues/1305">#1305</a>](<a
href="https://redirect.github.com/rust-lang/regex/issues/1305">rust-lang/regex#1305</a>):
Switches the <code>doc_auto_cfg</code> feature to <code>doc_cfg</code>
on nightly for docs.rs builds.</li>
</ul>
<h1>1.12.1 (2025-10-10)</h1>
<p>This release makes a bug fix in the new
<code>regex::Captures::get_match</code> API
introduced in <code>1.12.0</code>. There was an oversight with the
lifetime parameter
for the <code>Match</code> returned. This is technically a breaking
change, but given
that it was caught almost immediately and I've yanked the
<code>1.12.0</code> release,
I think this is fine.</p>
<h1>1.12.0 (2025-10-10)</h1>
<p>This release contains a smattering of bug fixes, a fix for excessive
memory
consumption in some cases and a new
<code>regex::Captures::get_match</code> API.</p>
<p>Improvements:</p>
<ul>
<li>[FEATURE <a
