+
+## What's new
+* Connector server and batch API stability fixes:
+    * Fixed WebSocket client wedging that made `OpenICFWebSocketTest` flaky
+    * Serialized WebSocket message dispatch per socket to prevent out-of-order processing
+    * Fixed lost pre-handshake responses that caused `testAsynchronousBatch` to hang
+    * Fixed a race in `BatchApiOpImpl.CompletionListener.start()` causing an intermittent `IllegalThreadStateException`
+    * Delivered `CancelOpRequest` messages arriving before the operation registers
+    * Gave each Jetty connection its own endpoint and closed cached principals
+    * Called `adapter.close()` from the Grizzly WebSocket close callbacks
+* Migrated `connector-server-jetty` off the deprecated `org.eclipse.jetty.util.log` API
+* Switched the LDAP connector tests to run against an embedded OpenDJ, allowing 30 s for it to start and stop, and made the changelog wait in `SunDSChangeLogSyncStrategyTests` deterministic
+* Modernized the OpenICF Docker images and broadened their multi-architecture build matrix
+* Added a CodeQL code-scanning workflow, trimmed the macOS/Windows build matrix and added workflow concurrency
+* Enabled Javadoc doclint `all,-missing` with `failOnWarnings` and bumped the Javadoc plugin to 3.12.0
+* Kept the Derby test dependency on a Java 11-compatible release (10.15.2.0)
+* Updated OpenDJ dependency to version 5.1.2
