Hi,
Earlier this week, I was asked, how does one keep track of Fedora update information? Is there a equivalent to RHN errata for RHEL? The answer is a bit more detailed and depending on what you want, there are multiple avenues for update information. Note that unlike many other distributions, Fedora updates are not limited to just security and bug fixes and often contain new major upstream releases as well.

Fedora package announce list. We use mailman filters so that you can choose to filter out which releases you get update information for

Also, yum has a number of nifty plugins. One of them called yum-changelog is useful for listing the RPM changelog information before or after an update for review.
Another plugin that is useful for getting just the security updates.
Refer the following (articles refer to RHEL but this works on Fedora as well)

Hope that helps.
