Tomorrow Debian 12 will release.
Change log: https://www.debian.org/releases/testing/releasenotes
In my opinion, the most significant change is the inclusion of nonfree firmware on the ISO, the detection of hardware that works well with that firmware during the installation process, and the suggestion to use that firmware. I also don’t recall having Cinnamon as a DE option in 11, but I could be wrong about that because it’s been a while since I last installed that version with a GUI.
Other than that, even though it falls under the “software updates” umbrella, I think the inclusion of a newer Flatpak runtime in the Bookworm repos is great news. Makes it a lot easier to use the latest version of Firefox, for example, without having to add other repos (for either Firefox or Flatpak).
