I've added what I have so far to the 'mplayer2-transitional' branch in
the mpv git repo. It now has a NEWS file.

Support for libbs2b was removed in mpv 0.11. Quoting the release notes:
"
audio/filter: remove center, extrastereo, karaoke, sinesuppress, sub,
surround, sweep, ladspa, hrtf, export and bs2b filters (these are
either considered useless or have replacements in lavfi)
"

gnome-mplayer was removed from stretch
smplayer from stretch uses mpv directly

Thanks,
James
