Basic care would involve making sure the patches had made it into the wild before ending the embargo, and nagging the relevant parties if not.

Edit: As of this writing, most distros including Redhat, Fedora, Debian Stable, do not have patches available in the package repos, though they're being actively worked on.

only for versions 6.19.12 & 6.18.22. older versions (which are used in distributions) are not ready yet.
