+Version 4.6.1
+(released 26 Jan 2017)
+
+ NAV has moved to GitHub. Issues are now tracked at
+ https://github.com/UNINETT/nav/issues . Due to the migration of bug data from
+ Launchpad, reporter and subscriber information has been lost (all bugs appear
+ to be reported by jmbredal).
+
+ If you have existing bug reports you still wish to keep an eye on, you can
+ find the migrated issue by searching the Launchpad bug number in our GitHub
+ issue tracker.
+
+ Fixed issues in this release:
+
+  * #320  (Error in IPAM function after upgrade to 4.6)
+  * #321  (Graph widget modifies graph interval to 24 hours, no matter what
+           the URL says)
+  * #891  ("rooms with active alerts"-widget needs event filter)
+  * #892  (cancelled maintenance tasks with no endtime are displayed)
+  * #893  (Long log lines cause logging to stop for ipdevpoll processes in
+           multiprocess mode)
+  * #1022 (Some dropdowns not sorted in Alert Profiles)
+  * #1024 (support external links in ups widget)
+  * #1425 (Using arrow keys to navigate when there is only a single
+           dashboard moves to a 'undefined' dashboard, resulting in a 404
+           Not Found)
+  * #1426 (Left/right arrow keys are captured globally on dashboards,
+           making it impossible to make small edits to widget titles and
+           such)
+  * #1238 (choose columns in status widget)
+  * #1412 (multiple dashboards should be presented as tabs)
