This is a hotfix release for v31.0.

Most noteworthy new features of v31.0:
- Big downloads player refactor: We now use the same player for downloads as for online streaming, so you can use much more features than with the old downloads player.
- Add search functionality for playlists and downloads
- Support for SponsorBlock's exclusive content and self promotion - in your feed, you can now see if a video is a fully sponsored video at first glance due to a marker on the video thumbnail
- SponsorBlock support for downloads
- And a lot more ...

Please see the changelog of the v31.0 release for more information.
