Hi,

This has been tagged. Source and binary archives are available [1]. This
release restores CMake target compatibility and fixes an issue with lossless
encoding when WEBP_REDUCE_SIZE is defined.

In the binary distributions:
  - The Windows builds were made using Visual Studio 2019; you may need to
    download the redistributables to run them
  - The Windows builds also have Unicode enabled (https://crbug.com/webp/559)

Everyone is encouraged to update, especially if you haven't upgraded to 1.2.3.
