+|RCE| 4.5.2 |RNS|
+-----------------
+
+Release Date
+^^^^^^^^^^^^
+
+- 2016-12-19
+
+
+New Features
+^^^^^^^^^^^^
+
+
+
+General
+^^^^^^^
+
+- Github authentication: no longer require repository permissions when
+  connecting RhodeCode account with Github login.
+- Api: added new function get_repo_refs. This was accidentally exposed in our
+  documentation as valid function, but wasn't implemented. This function is now
+  backported from next major release due the documentation issues.
+
+
+Security
+^^^^^^^^
+
+
+
+Performance
+^^^^^^^^^^^
+
+
+
+Fixes
+^^^^^
+
+- Api: Fixed a regression in API validation on create_* functions.
+  Before this fix it always converted given data to lowercase.
+- System info: fixed reporting of free inodes as taken.
+
+
+Upgrade notes
+^^^^^^^^^^^^^
