So for any given version e.g. 12.04, 12.10, 13.04,etc. a full changelog of all update packages e.g. MySQL, Apache, etc.?

Note: Raring Ringtail release notes says:

For a list of all packages being accepted for 13.04 Raring Ringtail, please subscribe to raring-changes.

The raring changes is a mailing list of nightmare proportions. Maybe there's a final, proofed, easy to understand, changelog of all updated packages?
