Dear Packagers and Devs, As we recently switched the rpm payload compression format to zstd, we had to give up 'zypper dup' compatibility from Leap < 15.2 to Tumbleweed. As we gave up on this compatibility, it is now time to also lift the limitation of using boolean dependencies. So far we only accepted boolean deps on Recommends: and Supplements: tags, but not on Requires:, as zypper dup could end up not being able to upgrade. Feel free to use those tags if they help you. Cheers, Dominique Boolean Deps Documentation: https://rpm.org/user_doc/boolean_dependencies.html
