As far as official Debian repositories are concerned: none that I know
of. It's quite different among 3rd-party repositories, though (that's

Point-releases modify the stable suite. I believe some bugfixes and
no-DSA security updates are shipped via point-release, without flowing
through DSA + -security. That's perhaps not a big deal, though.
