Not only the security fixes - 1.5.0.6 is a release fixing as far as I know only one regression, which is done in the latest 1.5.0.5 dapper package as well.
See: http://www.ubuntu.com/usn/usn-327-2 -- v15.0.6 is out! https://launchpad.net/bugs/56331 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
