Red Hat Enterprise Linux 9 became generally available recently. Version 3.35 of syslog-ng has been part of EPEL 9 (the semi-official extra software repo for RHEL maintained by Fedora packagers) for a while and now I enabled a few more destination drivers. I also enabled RHEL 9 support in my unofficial Git snapshot packages, so I can support RHEL 9 together with other RHEL and Fedora versions on the next syslog-ng release.
