mpv/RELEASE_NOTES

Release 0.33.0
==============

This release requires FFmpeg 4.0 or newer.

For packagers: Note that mpv's build system is only supported on Python 3.
If you use the `bootstrap.py` script it will take care of this, otherwise you
need to explicitly invoke the build system using `python3 waf`.
