Here is an update to libavif 1.4.0.


## [1.4.0] - 2026-03-04

### Added since 1.3.0

* Allow avifenc to read png or jpeg files through stdin using --stdin-format.
* Support some Sample Transform schemes as defined in the version 1.2 of the
  AVIF specification.
* Add an optional argument to the --depth flag of avifenc used to enable a bit
  depth extension scheme in the encoded file.
* Add support for converting jpeg files with Apple style gain maps.
* Add support for PNG cICP chunk when decoding PNG files. If a PNG file contains
  a cICP chunk and other color information chunks, such as iCCP (ICC profile),
  the other chunks are ignored as per the PNG Specification Third Edition
  Section 4.3.
* Support reading Sample-Transform-based 16-bit AVIF files when
  avifDecoder::imageContentToDecode & AVIF_IMAGE_CONTENT_SAMPLE_TRANSFORMS is
  not zero.
* Support Sample Transform derived image items with grid input image items.
* Add --sato flag to avifdec to enable Sample Transforms support at decoding.
* Add --grid option to avifgainmaputil.
* Apply clean aperture crop, rotation and mirror when decoding to PNG or JPEG.
  Remove orientation information from Exif if present.
* Add avif::RGBImageCleanup to the C++ API.
