The decoding speed has been improved by about 8% on x86 CPUs thanks to more SIMD acceleration and optimized CABAC code. Also the startup time has been improved, which gives a 3% speed improvement when decoding HEIC files with similar-sized tiles.
Build differences
When building shared-libraries in Release mode, we are now using -fvisibility=hidden by default. You can override this with the new cmake option "FORCE_FULL_VISIBILITY".
