To quickly review the latest changes to an rpm package, there’s a handy plugin for yum called yum-changelog. It’s part of the Fedora repository and can be installed by invoking

# yum install yum-plugin-changelog

The usage is quite self-explanatory, but here a a few useful examples anyway:

To list the whole changelog history of a package, run

# yum changelog all <packagename>

To list the changelog of a specific time period, e.g. this year:

# yum changelog 2013-01 <packagename>

To list the changelog of packages about to be updated:

# yum update <packagename> --changelog
