 ## Bugfix Releases
 
+### 2.13.3 {#2.12.3}
+
+* [Issue 4633](https://bugs.chromium.org/p/gerrit/issues/detail?id=4633):
+Filter out unrelated projects when getting project watches from index.
+
+* [Issue 4848](https://bugs.chromium.org/p/gerrit/issues/detail?id=4848):
+Upgrade Postgresql JDBC driver to 9.4.1211.jre7.
+
+  Older versions of Postgresql JDBC driver rely on finalize() methods in
+  order to avoid leaking unclosed database objects. Given finalize
+  methods are unpredictable (no guarantee about prompt execution, if at
+  all), in some high load environments this could lead to a memory leak
+  with millions of JDBC objects pending finalization.
+
+* [Issue 4841](https://bugs.chromium.org/p/gerrit/issues/detail?id=4841):
+Hooks plugin: Make sure `GIT_DIR` environment variable is set in `ref-update`
+hook.
+
+* Hooks plugin: Always return the output from the `ref-update` hook.
+
+  The output of the `ref-update` hook is now sent back to the client.
+
+* Fix migration to schema version 127 on case-sensitive file systems.
+
+* Fix internal server error caused by plugin returning null for
+external included-in.
+
+* Fix internal server error in `set-members` command when a group
+to be added is not visible to the caller.
+
+* Fix reindexing change by ssh command.
+
+  When reindexing a change by ssh, the change was loaded from the
+  index rather than from the database.
+
+* Export prolog runtime in plugin API.
+
+
 ### 2.13.2 {#2.13.2}
