+
+Bug Fixes
+---------
+
+* Fix synchronization of Myers diff and Histogram diff invocations.
++
+The fix for
+link:https://code.google.com/p/gerrit/issues/detail?id=3361[Issue 3361]
+that was included in Gerrit versions 2.10.7 and 2.11.4 introduced a
+regression that prevented more than one file header diff from being
+computed at the same time across the entire server.
+
+* Fix `sshd.idleTimeout` setting being ignored.
++
+The `sshd.idleTimeout` setting was not being correctly set on the SSHD
+backend, causing idle sessions to not time out.
+
+* Add the correct license for AsciiDoctor.
++
+AsciiDoctor is licensed under the MIT License, not Apache2 as previously
+documented.
