There is a feature
apt-get has and
yum misses: the ability to show installed packages versions, when asking confirmation about upgrading. There is a list of the about-to-be-installed packages version numbers, but not the already installed versions.
For example yum might tell you that you’re about to upgrade to apache v2.2.14-2, but from which version? If you’re upgrading from v2.2.14-1, you should have nothing to worry about. If you’re upgrading to v2.2.13-4, maybe you’ll want to have a look to the changelog to check which features were added. If you’re upgrading to v1.3 (!), well, you might run into a couple of problems when trying to restart it afterwards :)
Well, this is what this plugin is made for. Here’s how it looks like:

I’ve made an rpm package for this plugin, if you want to try it, you can grab it here: yum-plugin-show-upgrade-versions-1.00-1.fc12.noarch.rpm.
It’s tagged for Fedora 12, but it should work on older versions I suppose…
