<blockquote>
<h2>v3.19</h2>
<ul>
<li>Restore the <code>std3_rules</code> option, which had no effect
since changes
to UTS <a href="https://redirect.github.com/kjd/idna/issues/46">#46</a>
processing in Unicode 16. Note that <code>uts46_remap()</code>
defaults to enabling STD3 rules, so direct callers will see input
containing non-LDH ASCII characters rejected again.</li>
<li>Performance improvements to UTS <a
href="https://redirect.github.com/kjd/idna/issues/46">#46</a> mapping,
particularly for
ASCII-only domains.</li>
<li>Test on free-threaded CPython with the GIL disabled and document
thread safety.</li>
<li>Expose the Unicode version of the generated tables as
<code>idna.unicode_version</code>, and show it in <code>idna
--version</code>.</li>
<li>Add <code>code</code>, <code>text</code>, <code>codepoint</code> and
<code>position</code> attributes to
<code>IDNAError</code> so that the failed rule and the offending
character can
be identified without parsing the exception message.</li>
<li>The deprecated <code>transitional</code> argument to
<code>encode()</code> and
<code>uts46_remap()</code> is now completely ignored, and gives a
deprecation warning
for the latter.</li>
<li>Reject A-labels that are not the canonical Punycode encoding of
their U-label.</li>
<li>Fix CONTEXTJ violations raising <code>IDNAError</code> instead of
<code>InvalidCodepointContext</code>.</li>
<li>Consistently raise <code>IDNAError</code> for empty labels and
non-ASCII bytes
passed to label helper functions and the incremental codec.</li>
<li>Add property-based tests, extended fuzzing targets, coverage
measurement, and CI checks that the data tables match the generator
output.</li>
<li>Various code quality and tooling improvements.</li>
</ul>
