Debian 11 "bullseye" released

Please note that if you have default-release or pinning setup, you will need to adjust your config to account for the new security suite name:

https://www.debian.org/releases/bullseye/amd64/release-no...

If your APT configuration also involves pinning or APT::Default-Release, it is likely to require adjustments as the codename of the security archive no longer matches that of the regular archive. An example of a working APT::Default-Release line for bullseye looks like:

APT::Default-Release "/^bullseye(|-security|-updates)$/";

which takes advantage of the undocumented feature of APT that it supports regular expressions (inside /).
