+
+# Fixes
+
+* #811 Fix user email update failures
+
+# Build Changes
+
+* Github Actions no longer maintains a build for Ubuntu Bionic (18.04),
+  so automated `bionic` builds are no longer available. Automated builds
+  for 22.04 Jammy have been added with the `jammy` label.
+
+# Advisory
+
+This is a pre-release and may not be stable for production use. The username
+update feature is under development and will currently update the username of
+any user that can be identified as being in need of a username update. This
+may have unexpected side effects.
