As of 10/1/24 3:52 UTC time, Trixie/Debian testing does not have a fix for the severe cupsd security vulnerability that was recently announced, despite Debian Stable and Unstable having a fix.
Debian Testing is intended for testing, and not really for production usage.

So the way Debian Unstable/Testing works is that packages go into unstable/ for a bit, and then are migrated into testing/trixie.
Issues preventing migration:
∙ ∙ Too young, only 3 of 5 days old
Basically, security vulnerabilities are not really a priority in testing, and everything waits for a bit before it updates.
I recently saw some people recommending Trixie for a "debian but not as unstable as sid and newer packages than stable", which is a pretty bad idea. Trixie/testing is not really intended for production use.
If you want newer, but still stable packages from the same repositories, then I recommend (not an exhaustive list, of course).:
- Opensuse Leap (Tumbleweed works too but secure boot was borked when I used it)
- Fedora
If you are willing to mix and match sources for packages:
- Flatpaks
- distrobox — run other distros in docker/podman containers and use apps through those
- Nix
Can get you newer packages on a more stable distros safely.
Why bother? Backporting security updates or updating packages is work and in case of debian often unpaid. Trixie is for testing new packages and configurations, does not make a ton of sense to keep everything up to date.
