Tomorrow Debian 12 will release.
Change log: https://www.debian.org/releases/testing/releasenotes
Migrated to Debian 11 from Ubuntu 6 months ago. Loving it.
With Ubuntu I used to stick to the LTS releases and wait for a .1 upgrade. But I’ve been running a Debian 12 VM in anger (ie actually doing work on it - I needed PHP 8) for the last month or two and it’s been faultless for me. Might break the habit and upgrade the main machine early :)
Edit: almost pulled the trigger a little early tonight. Ironically the one package I have that doesn’t seem to exist for 12 yet is Virtualbox - not something I could install & test in my Debian 12 VM…
As the manual says you should run
apt list '?narrow(?installed, ?not(?origin(Debian)))'
before upgrading to check what non-Debian packages you have installed.
