AVStream, and again, there was *no* breakage in 3,1. A public field was added above private fields. The breakage is what we're now introducing in 3.1.1 to keep people misusing the API happy. if we add a line here, it should mention how we're in breaking the 3.1 ABI to make 3.1.1 compatible at runtime with API-violating applications built against 3.0 > + > + Because of this, ffmpeg and ffplay built against lavf>=6.42.100 will not be > + compatible with lavf>=57.41.100.

This was the only real breakage that's getting fixed.
