Everyone is encouraged to update. This will be finalized in the next few weeks
if there aren't any regressions.

As mentioned in https://crbug.com/webp/575, there's an incompatibility in this release due to a CMake target name change: WebP::libwebpmux -> WebP::webpmux. Projects may need to be updated if they're depending on the library. You can star the bug to track updates.
