13+ * Add support for outputting all frames of an image sequence in ` avifdec ` .
14+ ` avifdec --index all sequence.avif out.png ` creates files named
15+ ` out-xxxxxxxxxx.png ` where xxxxxxxxxx are the zero-padded frame indices.

19+ * Fix local libargparse dependency patch step on macOS 10.15 and earlier.
20+ * Patch local libyuv dependency for compatibility with gcc 10.
21+ * Use stricter C99 syntax to avoid related compilation issues.
22+ * Reject the conversion in avifenc from non-monochrome/monochrome to
23+ monochrome/non-monochrome when an ICC profile is present and not explicitly
24+ discarded.

29+ * Turn on the gain map API. Remove the AVIF_ENABLE_EXPERIMENTAL_GAIN_MAP CMake
30+ flag.
31+ * Allow YCgCo_Re and YCgCo_Ro encoding/decoding and update the enum values to
32+ the latest CICP specification. Remove the AVIF_ENABLE_EXPERIMENTAL_YCGCO_R
33+ CMake flag.
1234* Add the properties and numProperties fields to avifImage. They are filled by
1335 the avifDecoder instance with the properties unrecognized by libavif. They are
1436 written by the avifEncoder.
1537* Add avif(Un)SignedFraction structs and avifDoubleTo(Un)SignedFraction
1638 utility functions.
1739* Add 'avifgainmaputil' command line tool to installed apps.
1840* Add avifCropRectRequiresUpsampling().
41+ * Add experimental support for PixelInformationProperty syntax from HEIF 3rd Ed.
42+ Amd2 behind the compilation flag AVIF_ENABLE_EXPERIMENTAL_EXTENDED_PIXI.

44+ BIT_DEPTH_EXTENSION_12B_8B_OVERLAP_4B.

2857 writer_version > 0 correctly.

30- map metadata is always parsed if present and if this feature is compiled in.
31- Replace enableDecodingGainMap and ignoreColorAndAlpha with a bit field to choose
32- image content to decode. Remove gainMapPresent: users can check if
