I'm interested in having PHP 8.1 (https://www.php.net/releases/8.1/) available in AppStream for CentOS Stream 8. Currently CentOS Stream 8 has PHP 7.2, 7.3, 7.4, and 8.0 available. https://www.php.net/releases/8.1/ (Is there anything I can do to help make this happen? I started going through https://docs.centos.org/en-US/stream-contrib/quickstart/ and found https://gitlab.com/redhat/centos-stream/rpms/php, but that repo seems to only have a c9s branch, not CentOS Stream 8.)
At the moment we are working on PHP 8.1 to CentOS Stream 9 - and then introduce it in to RHEL 9. We've no immediate plans to add PHP 8.1 to RHEL 8, but we can keep this bug open to track the request.
Short status update. At the moment, PHP 8.0 is available in RHEL 8 and PHP 8.1 is available in RHEL 9. We have no immediate plans to add PHP 8.1 to RHEL 8.
