Vadim just released the third release, which would be the release candidate for 3.10, last Monday.
Changes on this release are addition of the notification and search features (though searching is actually filtering for this cycle), MPRIS fixes, lots of bug fixes and several added and updated translations.
Playlists didn’t make it this time (not enough approval for string freeze break, and it is a large feature too late for this cycle).
I already gave some information and screenshots on the two new features, so I won’t explain much anymore. I’ll just add that it is Shivani, Vadim and Seif who worked on search, while it is Eslam, Sai and me who worked on playlists view.
Even if it is in this release, I want to add more info to the playlists view. Eslam worked on the initial code for loading the playlists and did most of the design of the view, Sai is the one who wrote the Add to Playlists dialog and worked on the loading of the view and several fixes to selection mode and playlists view, while all I did was to do cleanups, port some of Eslam’s code to Python and add the missing bits.
You could still use the playlists view if you have gnome-music-preview installed from OBS, or you use the freeze-break (outdated) or preview branches in our GNOME or GitHub git repositories, respectively.
As for MPRIS, I fixed the loading of default playlist (Songs view) which was broken by search and notifications, and fixed closing and thumbnails which was broken before the first unstable release.
Thanks to Juan A. Suarez Romero for helping us out on this release!
Edit: Forgot to say that Add to Playlists now works in all views, Remove from Playlists now working (though it will always remove the first track if you have two or more copies of a single song), and search/filtering now works in Playlists view too.
