The following packages have been upgraded in the Cygwin distribution: * libwebp 1.2.2 * libwebp-devel 1.2.2 * libwebp7 1.2.2 * libwebpdecoder3 1.2.2 * libwebpdemux2 1.2.2 * libwebpmux3 1.2.2 WebP is a modern web image format with superior compression. WebP lossless images are 26% smaller in size compared to PNGs. Lossless WebP supports (alpha channel) transparency at a cost of 22% overhead. WebP lossy images are 25-34% smaller than JPEG images at equivalent quality. Lossy WebP supports transparency with 3× smaller file sizes than PNG. A WebP file consists of VP8 or VP8L image data in a RIFF container.
