+|RCE| 4.26.0 |RNS|
+------------------
+
+Release Date
+^^^^^^^^^^^^
+
+- 2021-08-06
+
+
+New Features
+^^^^^^^^^^^^
+
+
+
+General
+^^^^^^^
+
+- Caches: introduce invalidation as a safer ways to expire keys, deleting them are more problematic.
+- Caches: improved locking problems with distributed lock new cache backend.
+- Pull requests: optimize db transaction logic.
+  This should prevent potential problems with locking of pull-requests that have a lot of reviewers.
+- Pull requests: updates use retry logic in case of update is locked/fails for some concurrency issues.
+- Pull requests: allow forced state change to repo admins too.
+- SSH: handle subrepos better when using SSH communication.
+
+
+Security
+^^^^^^^^
+
+- Drafts comments: don't allow to view history for others than owner.
+- Validators: apply username validator to prevent bad values being searched in DB, and potential XSS payload sent via validators.
+
+
+Performance
+^^^^^^^^^^^
+
+- SSH: use pre-compiled backends for faster matching of vcs detection.
+- Routing: don't check channelstream connections for faster handling of this route.
+- Routing: skip vcsdetection for ops view so they are not checked against the vcs operations.
+
+
+Fixes
+^^^^^
+
+- Permissions: flush all users permissions when creating a new user group.
+- Repos: recover properly from bad extraction of repo_id from URL and DB calls.
+- Comments history: fixed fetching of history for comments
+- Pull requests: fix potential crash on providing a wrong order-by type column.
+- Caches: report damaged DB on key iterations too not only the GET call
+- API: added proper full permission flush on API calls when creating repos and repo groups.
+
+Upgrade notes
+^^^^^^^^^^^^^
+
+- Scheduled release 4.26.0.
