[wildfly-dev] Where is jboss fork of Jakarta EE transactions spec?

Hello, I was switching some artifacts from old java EE to their (so much better) Jakarta counterparts and I know we have some forks located under https://github.com/jboss. However, I couldn't locate up-to-date version of transactions api fork, the one we have there is https://github.com/jboss/jboss-transaction-api_spec which was last modified in 2017. Yet looking in WFLY POM, I can see that it uses a newer version of the same dependency - https://github.com/wildfly/wildfly/blob/master/pom.xml#L7181-L7185 Does anyone know if it was placed into another repository? Or perhaps mistakenly not pushed into the repository? Regards Matej
