Use CVS ? Use CVS2RSS to keep track of changes to your code? Moving your repository over to Subversion ? You’ll be wanting svnlog then.

It’s an eXSLT that transforms subversion (svn) log XML files into vaild RSS 2.0 feeds. Get it here.
It shows revision number and author in the RSS’s title; commit message, date and changed files in the description. There are some goodies in there, like links to the changed files and expansion of the file’s status. If you need a RSS feed for your Subversion repository, have a look.
