– Yes. We will switch the rpm compression from xz to zstd on 4.5.0. As the prerequisite, we have enabled zstd in deltarpm and related tools in the 4.4.0 release.

To ask this here, too … ist zstd REQUIRED or an option as of 4.5. See: SFOS 4.5.0 switches RPM compression. What does that mean for existing RPMs?
