• Added WP CLI support. Add "wp webp-express convert" to crontab for nightly conversions of new images! Thanks to Isuru Sampath Ratnayake from Sri Lanka for initializing this.
• Added "sharp-yuv" (not as option, but as always on). Better YUV->RGB color conversion at almost no price. Read more here. Supported by cwebp, vips, gmagick, graphicsmagick, imagick and imagemagick
• Bumped cwebp binaries to 1.2.0
• cwebp now only validates hash of supplied precompiled binaries when necessary. This cuts down conversion time.
• Convert on upload now defaults to false, as it may impact upload experience in themes with many formats.
• bugfix: Alpha quality was saved incorrectly for PNG. Thanks to Chriss Gibbs from the UK for finding and fixing this.
• bugfix: wp-debug log could be flooded with "Undefined index: HTTP_ACCEPT". Thanks to @markusreis for finding and fixing this.
