Each of our themes and our Church Content Pro plugin have been updated for a better experience with WordPress 5.8 and PHP 8.
The core Church Content plugin did not need to be updated. Everything was reasonably compatible with WordPress 5.8 and PHP 8 before these updates so we waited a bit to release them after WordPress 5.8 came out in order to run through a list of minor bugs reported by users over the months. There are other improvements such as automatically linked phone numbers.
