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.

No its pretty much perfect seas.

Youtube has plenty of reviews by the gurus.

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.
