Anything I should look out for, or smooth sailing?

I am using Cinnamon + X11 + Nvidia, everything working as it should. I use Distrobox and Flatpaks for additional packages, so I don’t really touch the base install much but it seems rock solid as expected from Debian.

Previous release had PHP 7.4, new one has 8.2. Nextcloud 24 supports 7.2 - 8.0, 25 supports 7.2 - 8.1 and 26 supports 8.0 - 8.2, which is a bit inconvenient.

To upgrade, I first¹ upgraded Nextcloud to 25, then PHP to 8.2, removed the versioncheck in Nextcloud to accept PHP 8.2 and then upgraded to Nextcloud 26.

Otherwise very smooth - even the usrmerge was absolutely event-free.

¹) of course what I actually did first was upgrade Debian/PHP without checking beforehand and then installing PHP 7.4 from the previous release again.

Depends on your hardware. My ThinkPad Z16 on KDE would freeze on resume from suspend and the lock screen would crash. The keyboard would be unusable and I couldn’t switch to a vtty console. No such bug on my other ThinkPads, and it doesn’t happen using Gnome on the same ThinkPad. Additionally, it doesn’t happen using KDE on the same ThinkPad with another distribution. Just a weird bug.

Everything else has been smooth.

I’m daily driving it on my laptop. No issues and the addition of the non-free firmware on the installer makes installation much smoother.

Have had it on my laptops since package freeze. No problems to report. Will switch my desktop and work PC (from Ubuntu) when I can be bothered.

Upgraded two servers and my main machine. Really nice to be on the new system.

Unfortunately disaster in that Kdiff3 crashes when you try and paste new text over previous text. You can use it once, then you have to restart it to use it a second time. Everything else appears to be a better solution.
