So I ran into an actual issue that needs 0.33
The mp command of "playlist-play-index" in order to programmatically index a playlist has no previous equivalency (other than perhaps incrementally rolling around - but it's not the same) and I had put it in some lua script that then borked at me because it's a 0.33 introduction.
I hope this isn't being a pest here, the 0.33 release was nov 22, 2020
Thanks
