Please note that backwards compatibility is not maintained during this update. HEIF source code and website is updated to reflect the latest HEIF specification changes and various fixes. Example configuration files for generating multi-layered streams can be found in the Wiki. Minor bug fixes are included in this update. The source code now includes structures that are specified in this second edition. ISO/IEC 23008-12 second edition includes support for the interchange of multi-layered images.

Implementation is based on HEIF standard specification ISO/IEC 23008-12:2017 that is available from iso.org web pages. Writer executable replaced with writer library / API. Reader API update, bug fixes and examples update.

The Java API is expected to remain relatively stable, however the new C++ API will most likely change in the future. Two new APIs added, a Java API which wraps the C++ libraries using JNI and a convenience C++ API (which is used by the Java API) that wraps the underlying reader and writer. v3.3.0 Release: Java desktop build added, Java API includes track and image sequence as well as entity grouping support. Bug fixes, code cleanup and robustness improvements. Bug fixes, minor improvements and code cleanup. v3.5.0 Release: Improved support for JPEGs and edit lists. v3.6.0 Release: Added support for several new properties, image items with decoding dependencies, Extended type box and Type combination box, associating properties for entity groups, and reader support for segmented tracks.
