Found some issues with the bulk action to add channels to custom playlists. When using the group assignment it was not working correctly. If you're not using Custom Playlist, you can safely ignore this release.
Fixes
Custom groups/category assignment (e254c12)
Bulk action from Channels and VOD table was completely incorrect, assigning tags to playlist instead of channels. Within Custom Playlist mgmt. assigning groups/categories was adding and removing others, which it should not do. Also missing cleanup function when custom playlist deleted or channels detached. This should all be fixed up now!
