Changes for 0.3.1 'Sailfish': ------------------------------ - Fix a buffer overflow in frame-threading mode on SSSE3 CPUs - Reduce binary size, notably on Windows - SSSE3 optimizations for ipred_filter - ARM optimizations for MSAC Changes for 0.3.0 'Sailfish': ------------------------------ This is the final release for the numerous speed improvements of 0.3.0-rc. It mostly: - Fixes an annoying crash on SSSE3 that happened in the itx functions Changes for 0.2.2 (0.3.0-rc) 'Antelope': ----------------------------- - Large improvement on MSAC decoding with SSE, bringing 4-6% speed increase The impact is important on SSSE3, SSE4 and AVX-2 cpus - SSSE3 optimizations for all blocks size in itx - SSSE3 optimizations for ipred_paeth and ipref_cfl (420, 422 and 444) - Speed improvements on CDEF for SSE4 CPUs - NEON optimizations for SGR and loop filter - Minor crashes, improvements and build changes Changes for 0.2.1 'Antelope': ---------------------------- - SSSE3 optimization for cdef_dir - AVX-2 improvements of the existing CDEF optimizations - NEON improvements of the existing CDEF and wiener optimizations - Clarification about the numbering/versionning scheme Changes for 0.2.0 'Antelope': ---------------------------- - ARM64 and ARM optimizations using NEON instructions - SSSE3 optimizations for both 32 and 64bits - More AVX-2 assembly, reaching almost completion - Fix installation of includes - Rewrite inverse transforms to avoid overflows - Snap packaging for Linux - Updated API (ABI and API break) - Fixes for un-decodable samples Changes for 0.1.0 'Gazelle': ---------------------------- Initial release of dav1d, the fast and small AV1 decoder. - Support for all features of the AV1 bitstream - Support for all bitdepth, 8, 10 and 12bits - Support for all chroma subsamplings 4:2:0, 4:2:2, 4:4:4 *and* grayscale - Full acceleration for AVX-2 64bits processors, making it the fastest decoder - Partial acceleration for SSSE3 processors - Partial acceleration for NEON processors
