PHP 8.1.x Support
Beginning with VaultWiki 4.1.5, we will now support installations running PHP 8.1.x. After close to 6 months of low-traffic testing, we believe that we have addressed a majority of the compatibility issues with the newest branch of PHP.While we believe VaultWiki will now run on these versions of PHP, we expect that there are still issues that may be revealed in higher-use environments, so please take that into consideration when upgrading PHP. Also remember that in addition to VaultWiki, you must be using a compatible release of forum software, such as XenForo 2.2.9 or higher.
