* 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

- When opening tiled images, do not check against maximum image
size immediately to allow for tile-based decoding of very large
images.
- Several smaller fixes in writing image sequences
- CMake option to disable building of heif-view, which pulls in
dependency on SDL
- Fixes reading/writing of GIMI content IDs
- Some build fixes

- Fixes a bug in decoder plugin loading.
- Changes from 1.20.0:
- Sequences:
- API for reading and writing image sequences. You can read and
write sequences for all codecs (not just H.265 / AV1, but
also JPEG-2000, ISO-23001-17 uncompressed, ...). Currently
only intra-coded sequences are supported.
- API for reading and writing metadata sequences. The metadata
tracks can contain any raw timed data.
- Support for SAI (sample auxiliary information). Timed samples
(from image sequences or metadata) can have auxiliary data
attached. Currently we support TAI timestamps and GIMI
content description IDs.
- Support for track references.
- The API for sequences is described here:
https://github.com/strukturag/libheif/wiki/Reading-and-Writing-Sequences
- New command line tool heif-view to show HEIF sequences
(requires libSDL).
- Other new features:
- You can specify a security limit for the maximum total memory
libheif may use for decoding. This is easier to handle than
specifying limits on the maximum image size or single memory
allocations.
- Support for TAI timestamps (in images and sequences) has been
promoted from experimental to stable.
- FFMPEG plugin now supports HDR decoding
- Header files are now split into individual headers by topic.
However, it should still be backwards compatible with heif.h
being a catch-all covering the old content. For new

* Set essential flag for transformative properties as required by
MIAF. This fixes the display of AVIF images with transformations
encoded by libheif in Chrome, which checks whether this flag is
set. This mainly affected images encoded by ImageMagick.
* If the environment variable LIBHEIF_SECURITY_LIMITS is set to OFF,
libheif will not check any security limits. This can be used if a
user works with large images and the application software does not
allow to adjust the libheif security limits.
* Resolved processing 16-bit JPEG-2000

* error when using a chroma format or bit depth that is not supported
by the Kvazaar plugin

* Fixes backwards compatibility of heif_context_set_maximum_image_size_limit()
- update to 1.19.0:
* The major new feature in this decoding separate tiles of images and
also encoding an image tile by tile. This allows to process
high-resolution images that do not fit into memory. We support three
tiling methods:
- grid, which is the default tiling method used in most existing
HEIC or AVIF images.
- unci, which is the built-in tiling method of the ISO 23001-17
uncompressed codec.
- tili, which is a proprietary scheme with much less overhead than
grid and which supports efficient streaming of high-resolution
images over networks without having to download huge amounts of
metadata. It also supports much larger images than possible with
grid. As an extra, it supports the processing of multi-dimensional
images, like 3D image cubes, or image sets addressed by several
parameter dimensions.
* decoding is faster, especially if you let libheif decide on the best
colorspace to work in by passing heif_colorspace_unknown and
heif_chroma_unknown to heif_decode_image(). It will then use the
input colorspace and avoid unnecessary conversions.
* support for multi-resolution pyramids (pymd) to show downscaled
versions of high-resolution images
* improved reader interface that enables to connect libheif to a
network source. Libheif will request the portions of the image file
that have to be downloaded from the server. This is especially
useful in connection with the tiling / multi-resolution pyramid
feature.
* function to generate overlay images
* decoding progress is signaled to the client application and decoding
can be cancelled
* decoding of AVC encoded images through OpenH264
* security limits can be changed to be able to read very large images
- Skip test when HEVC encoder is unavailable
