- 7/17/12: version 0.1.99 * Alpha channel encode/decode support. * Lossless encoder/decoder. Incompatible changes: * The encode ABI has been modified to support alpha encoding. * Deprecated function WebPINew() has been removed. * Decode function signatures have changed to consistently use size_t over int/uint32_t. * decode_vp8.h is no longer installed system-wide. - 9/19/11: version 0.1.3 * Advanced decoding APIs. * On-the-fly cropping and rescaling of images. * SSE2 instructions for decoding performance optimizations on x86 based platforms. * Support Multi-threaded decoding. * 40% improvement in Decoding performance. * Add support for RGB565, RGBA4444 & ARGB image colorspace. * Better handling of large picture encoding. - 3/25/11: version 0.1.2 * Incremental decoding: picture can be decoded byte-by-byte if needs be. * lot of bug-fixes, consolidation and stabilization - 2/23/11: initial release of version 0.1, with the new encoder - 9/30/10: initial release version with only the lightweight decoder
