+------------------
+
+Release Date
+^^^^^^^^^^^^
+
+- 2019-10-28
+
+
+New Features
+^^^^^^^^^^^^
+
+
+
+General
+^^^^^^^
+
+- Permissions: properly flush user cache permissions in more cases of permission changes.
+  Some API methods and user-group additions didn't invalidate permission caches resulting in
+  users not seeing the permission changes immediately.
+- Pull requests: properly handle exceptions in state change logic, and improve logging on this.
+
+
+Security
+^^^^^^^^
+- Security: fixed XSS in file editing.
+
+
+Performance
+^^^^^^^^^^^
+
+
+
+Fixes
+^^^^^
+
+- Diffs: handle paths with quotes in diffs.
+- Diffs: fixed outdated files in pull-requests re-using the filediff raw_id for anchor generation.
+  This could make rendering diff crash in cases of only having outdated files in a diff.
+- Diffs: handle very odd case of binary, corrupted diffs which crashed the diff parser.
+- Svn: handle non-ascii message editing.
+
+
+Upgrade notes
+^^^^^^^^^^^^^
+
+- Scheduled release addressing problems in 4.17.X releases.
