Yesterday Miklos bumped pacman-g2 to 3.8.7 in current, so what’s the point? It includes also my patch that adds a new capability: now it can downgrade packages! (eheh ok it’s not that cunning, afaik Archlinux’s pacman can do it since ages)
When using WIP repos, you may need to drop them and downgrade all the packages to the version that is in the -current repo. While this operation is quite easy (pacman already prints the packages that are newer than the ones in the repo so, once you have that list in a reasonable shape, you just have to reinstall them), I think it’s handy an option to let pacman do it for you.
From now you can use
pacman-g2 -Suu to downgrade all the packages with a version number higher
than the one in the repo.
