* This patch release only fixes a build error with some GCC versions
because of a missing #include.
- update to 1.21.0:
* This release adds full support for reading and writing HEIF image
sequences. libheif will now encode HEIF image sequences with all
included codecs.
* Since HEIF image sequences are very similar to MP4 videos, this new
version is also capable of decoding most MP4 videos (without audio,
of course).
* heif-enc documentation for sequence encoding
* API documentation for reading and writing sequences
* Support for image sequences with alpha channels. For most codecs,
the alpha channel will be stored in a separate, auxiliary,
monochrome track. For ISO/IEC 23001-17 (uncompressed) streams, the
alpha channel is stored in the main video track.
* Support for sequence track edit lists to define the number of
sequence repetitions (without actually repeating the video data).
* New encoder plugin using x264 to write H.264-compressed video
streams and images.
* The FFmpeg decoder plugin will now decode both H.265 and H.264.
* Support for HEIF text items and language properties.
* CVEs fixed: CVE-2025-68431
