Does this need to be a new Change Proposal or does this just need to go through the Fedora packaging committee? (Those involved in the Change like zbyszek can probably advise here) - should we extend this further and say, if we no longer assume NEVRAs are monotonically increasing in a new release, we should allow packagers to use this opportunity to drop epochs in Rawhide? (likely with proper announcement beforehand in devel@) (this might require coordination with RH's Leapp developers and AlmaLinux's ELevate developers, to make sure those support upgrading to lower NEVRAs too) Best regards, -- _o) Michel Lind (né Salim) _( ) identities: https://keyoxide.org/5dce2e7e9c3b1cffd335c1d78b229d2f7ccc04f2
