The following packages have been upgraded in the Cygwin distribution:

* libwebp		1.2.2
* libwebp-devel		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.

For more information see the project home page:

	https://developers.google.com/speed/webp/
