The new Mastodon release brings you a much better audio player and improved support for different audio and video formats, as well as some additional security mechanisms.
The audio player has been completely reworked to have a more eye-catching design. It will extract album art from the uploaded audio file automatically, or allow you to upload a thumbnail of your own choosing to be displayed in the center. Dominant colors from the artwork or thumbnail will then be used to give the player a unique look.
