 MumbleDJ Changelog
 ==================
 
+### November 5, 2016 -- `v3.2.1`
+* Fixed YouTube video offsets. Now YouTube URLs with `?t=<timestamp>` at the end will start the audio playback at the appropriate position.
+
+### November 5, 2016 -- `v3.2.0`
+* Fixed a Go panic that would occur when a YouTube playlist contained a private video.
+* Added back immediate skipping for tracks/playlists that are skipped by the submitter. This was a feature that was present in the last major version of MumbleDJ but was forgotten when rewriting the bot (sorry!).
+
+### August 22, 2016 -- `v3.1.4`
+* Fixed a SoundCloud API response parsing issue that would result in empty IDs for tracks.
+* Fixed the startup check for SoundCloud API.
+
+### August 21, 2016 -- `v3.1.3`
+* Fixed a deadlock that would occur during the transition from the first to second track in a queue.
+
 ### August 14, 2016 -- `v3.1.2`
 * Fixed an index out of range crash in the queue skipping function.
