fedup from 21 to 22 currently:
WARNING: problems were encountered during transaction test:
firefox-38.0-4.fc21.x86_64 requires libicu-52.1-6.fc21.x86_64
These packages may have problems after the upgrade.
this is because 38.0-4.fc21 has gone stable, but not 38.0-4.fc22. If we push it as a 0-day this will fix things on release day, but it'd be good to push it stable now to avoid problems during testing. This is an FE proposal bug.
Update is https://admin.fedoraproject.org/updates/firefox-38.0-4.fc22,thunderbird-31.7.0-1.fc22
Looks like there's a newer update in updates-testing now: https://admin.fedoraproject.org/updates/FEDORA-2015-8468/firefox-38.0.1-1.fc22
Discussed at today's blocker review meeting .
This bug was accepted as freeze exception: It'd be good to keep a clean upgrade path.
firefox-38.0.1-1.fc22 was pushed to stable; closing the ticket.
