API changes, most recent first:
2023-02-16 - xxxxxxxxxx - lavf 60.2.100 - avformat.h
Deprecate AVFormatContext io_close callback.
The superior io_close2 callback should be used instead.
2023-02-13 - xxxxxxxxxx - lavu 58.1.100 - frame.h
Deprecate AVFrame.coded_picture_number and display_picture_number.
Their usefulness is questionable and very few decoders set them.
