+#### <a id="debian-bookworm"/>Bookworm added and made default
+
+Bookworm was released on 2023-06-10, and will be the new default base container for Docker builds.
+Bullseye images will still be built and available as long as the OS build is current, tagged with the `-bullseye` suffix.
+
+#### <a id="debian-buster"/>Buster removed
+
+Buster LTS supports will stop in June 2024, and Vitess v18.0 will be supported through October 2024. 
+To prevent supporting a deprecated buster build for several months after June 2024, we are preemptively
+removing Vitess support.
