-- Core: Avoid endless loop if all tracks in the tracklist are unplayable and
-  consume mode is off. (Fixes: :issue:`1221`, :issue:`1454`, PR: :issue:`1455`)
+- Audio: Better handling of seek when position does not match the expected
+  pending position. (Fixes: :issue:`1462`, PR: :issue:`1496`)
 
-- File: Ensure path comparision is done between bytestrings only. Fixes crash
-  where a :confval:`file/media_dirs` path contained non-ASCII characters.
-  (Fixes: :issue:`1345`, PR: :issue:`1493`)
+- Audio: Handle bad date tags from audio, thanks to Mario Lang and Tom Parker
+  who fixed this in parallel. (Fixes: :issue:`1506`, PR: :issue:`1525`,

 - Core: Correctly record the last position of a track when switching to another
   one. Particularly relevant for `mopidy-scrobbler` users, as before it was
   essentially unusable. (Fixes: :issue:`1456`, PR: :issue:`1534`)
