+Since the 21.0.0 release, Kyle Barron has been invited to be committer.
+
+Matthijs Brobbel, Adam Reeve and Rossi Sun have been joined the
+Project Management Committee (PMC).
+
+Thanks for your contributions and participation in the project!
+
+The first Apache Arrow Summit was held on October 2nd 2025 in Paris, France
+as part of [PyData Paris](https://pydata.org/paris2025).
+Program details and agenda are here:
https://www.meetup.com/pydata-paris/events/310646396/
+
+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 A/V recording system was available for this event.

+## Arrow Flight RPC Notes

+Support for dictionary replacement and dictionary encoding has been added to
the DoGet and DoExchange methods.
