 ### Added
 - exposed util functions: `avifFullToLimitedY`, `avifFullToLimitedUV`, `avifLimitedToFullY`, `avifLimitedToFullUV`, `avifPrepareReformatState`
 
 ### Changed
 - Renamed ispeWidth/ispeHeight to containerWidth/containerHeight; they now can hold tkhd's width/height
 - Split avifImageYUVToRGB into faster internal functions (estimated gain: 3.5x)
+- Fixed a few memory leaks, one in the README, one in codec_dav1d (AurelC2G)
