I mean where latest NVR is not highest NVR :-)

Here is the current status:

Should they all be re-tagged or is there something to discuss for the ghc pacakges?

Not all seems to be bodhi problems, I've checked texmaker and here the previous f21 build was done from master branch, not f21 branch, causing the difference. So there might be more serious problems.

At least for the ghc-* stuff and any deps need to go via the maintainer.

the ghc packages need to be checked to make sure that the higher nvrs did not ship, if they shipped in a single compose then the maintainer needs to make sure there is an appropriate upgrade path from them.

f21 is EOL. Closing this.

If there's a problem on existing releases, please file a new ticket.
