I am in the process of upgrading Nextcloud 24.0.7 to 25.0.1, this likely will take awhile as it involves major changes in database schemas, etc.
However, one plus, I discovered part of the reason Nextcloud has been so slow. I’ve been using memcache and I’ve been using PHP 8.0, however memcache is configured to use aPCU and aPCU module was not enabled in PHP 8.0 so this broke memcache.
For some reason previous versions did not complain about this configuration issue, but now that this version did, it is corrected.
