The rebuild for modules and anything that links against PHP went quite well and I have moved the packages into [testing]. Even uwsgi did build with a simple patch. I did notice that this project is in maintenance mode according to upstream; so I am not that optimistic we can provide the PHP plugin in future. At least for PHP I highly suggest to use php-fpm instead. In general the actual breaking changes from 8.1 to 8.2 are minor. I expect most apps to work without or minimal changes; even though some of these might be quite subtile. See https://www.php.net/manual/en/migration82.incompatible.php
One of the special cases is probably nextcloud with its version check. I'd suggest to use php-legacy here is this will always point to a version that is supported by upstream.
Let me know of any issues that arise.
