After a server upgrade X2CRM stopped working. So I needed to make some updates to get it working for a client. They are posted on GH if anybody needs.
Updated to run using PHP 8.0x
Updated to make it work with modern MySql/MariaDB server ie, ONLY_FULL_GROUP_BY is now set by default, which totally breaks all the join/'group by' queries in X2CRM.
Updates to fix for vulnerabilities reported in CVE-2021-27288, CVE-2020-21088.
Added some bug fixes from ignored pull requests on main repo.
Added translation updates from ignored pull
