Change log is here: https://github.com/libjpeg-turbo/libjpeg-turbo/releases/tag/1.5.90 YUM repository is unfortunately not updated yet and won't be until SourceForge restores SSH access: https://sourceforge.net/p/forge/site-support/16424 (NOTE: If anyone knows of another file release system that supports interactive SSH and rsync access and provides download stats, please let me know. The only thing we're still using on SourceForge is the file release system, but I haven't yet found another one that meets the needs of this project. Refer to https://github.com/VirtualGL/virtualgl/issues/35 for discussion.) This release was made possible by a grant from the Mozilla Open Source Support (MOSS) program. Release Highlights: -- AVX2 (256-bit) SIMD acceleration for the colorspace conversion, chroma down/upsampling, integer quantization/sample conversion, and "slow" integer DCT/IDCT algorithms. This speeds up the overall performance of the library by about 15-20% on a Core i7 ("Haswell") CPU when using the "slow" integer DCT/IDCT (the "slow" integer DCT/IDCT now performs similarly to the "fast" integer DCT/IDCT on that platform.) Looking for feedback regarding the performance on other AVX2-equipped CPUs. Refer to https://github.com/libjpeg-turbo/libjpeg-turbo/issues/2 for discussion. -- SSE2 SIMD acceleration for progressive Huffman encoding. This speeds up the overall performance of progressive JPEG compression by almost 2x on SSE2-equipped CPUs. -- Complete build system overhaul. We are now using CMake and only CMake for all platforms. Refer to https://github.com/libjpeg-turbo/libjpeg-turbo/issues/56 for discussion. -- ICC profile read/write support in the libjpeg API -- Improved error handling in the TurboJPEG API (thread-safe error retrieval, optionally making libjpeg warnings fatal, determining whether a function failed due to a libjpeg warning or a fatal error.) -- BMP/PPM load/save support in the TurboJPEG API -- Loongson MMI SIMD acceleration for select algorithms, which speeds up compression by ~70-100% and decompression by ~2-3.5x. -- You received this message because you are subscribed to the Google Groups "libjpeg-turbo User Discussion/Support" group.
