Release 0.7.0

[InputUsername]

• Removed notification functionality
  • As an alternative, I recommend mpris-notifier.
• Made album name optional when submitting to ListenBrainz
  • ListenBrainz does not require album names for submissions, so they are now optional. This means tracks without xesam:album will still be submitted.
  • The Last.fm library used by rescrobbled still requires the album, but this restriction could be lifted in the future.
  • This does have the side effect of now treating empty album names (i.e. "") the same as if they were missing from the MPRIS metadata.
• Updated player finding logic to be more resilient to players that cause errors
• Moved to OpenSSL/libssl version 3
