+<h2>Community</h2>
+<p>Since the 21.0.0 release, Kyle Barron has been invited to be committer.</p>
+<p>Matthijs Brobbel, Adam Reeve and Rossi Sun have been joined the
+Project Management Committee (PMC).</p>
+<p>Thanks for your contributions and participation in the project!</p>
+<p>The first Apache Arrow Summit was held on October 2nd 2025 in Paris, France
+as part of <a href="https://pydata.org/paris2025"; target="_blank"
rel="noopener">PyData Paris</a>.
+Program details and agenda can be found here: <a
href="https://www.meetup.com/pydata-paris/events/310646396/"; target="_blank"
rel="noopener">https://www.meetup.com/pydata-paris/events/310646396/</a></p>
+<p>There were around 35 attendees, of which ~20 were existing core developers
or PMC members.
+The Summit was overwhelmingly described as a success, with a friendly
atmosphere between all participants.
+Unfortunately, no Audio / Video recording system was available for this
event.</p>

+you to the <a href="/release/22.0.0.html#changelog">complete changelog</a>.</p>
+<h2>Community</h2>
+<p>Since the 21.0.0 release, Kyle Barron has been invited to be committer.</p>
+<p>Matthijs Brobbel, Adam Reeve and Rossi Sun have been joined the
+Project Management Committee (PMC).</p>
+<p>Thanks for your contributions and participation in the project!</p>
+<p>The first Apache Arrow Summit was held on October 2nd 2025 in Paris, France
+as part of <a href="https://pydata.org/paris2025";>PyData Paris</a>.
+Program details and agenda can be found here: <a
href="https://www.meetup.com/pydata-paris/events/310646396/";>https://www.meetup.com/pydata-paris/events/310646396/</a></p>
+<p>There were around 35 attendees, of which ~20 were existing core developers
or PMC members.
+The Summit was overwhelmingly described as a success, with a friendly
atmosphere between all participants.
+Unfortunately, no Audio / Video recording system was available for this
event.</p>
