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.
