<blockquote>
<h1>1.8.4 (2023-06-05)</h1>
<p>This is a patch release that fixes a bug where <code>(?-u:\B)</code>
was allowed in
Unicode regexes, despite the fact that the current matching engines can
report
match offsets between the code units of a single UTF-8 encoded
codepoint. That
in turn means that match offsets that split a codepoint could be
reported,
which in turn results in panicking when one uses them to slice a
<code>&amp;str</code>.</p>
<p>This bug occurred in the transition to <code>regex 1.8</code> because
the underlying
syntactical error that prevented this regex from compiling was
intentionally
removed. That's because <code>(?-u:\B)</code> will be permitted in
Unicode regexes in
<code>regex 1.9</code>, but the matching engines will guarantee to never
report match
offsets that split a codepoint. When the underlying syntactical error
was
removed, no code was added to ensure that <code>(?-u:\B)</code> didn't
compile in the
<code>regex 1.8</code> transition release. This release, <code>regex
1.8.4</code>, adds that code
such that <code>Regex::new(r&quot;(?-u:\B)&quot;)</code> returns to the
<code>regex &lt;1.8</code> behavior of
not compiling. (A <code>bytes::Regex</code> can still of course compile
it.)</p>
<p>Bug fixes:</p>
