linux rpms unix sockets

Running an onion service in nginx on centos 7.9. Everything works great until I switch the connection to a unix socket. From my internet searches it seems tor version 0.26 is required for unix sockets, but the only version available to me is version 0.4. Am I missing something? Are the unix rpms really that far behind, are they a branch off the main source? How are people setting this up? How do I get a newer version of tor?
