This release includes WebP compression for PVRTC and ETC formats along with a few bug fixes.
Efficient WebP compression for PVRTC and ETC1
When selecting WebP compression for compressed texture formats (PVRTC1 and ETC1), the WebP compressor has up until now just been compressing the texture file as a raw LUM8 texture (an array of bytes). We have greatly improved this compression by transforming the compressed texture format data into data more suitable for WebP image compression using an internal intermediate format. This is then retransformed back into the compressed texture format when loaded by the run-time. This has shown an average improvement of anything between 40-60% over compressing with ZLib (or WebP with LUM8).
