1. We are pausing the osg-ca-certs, osg-ca-certs-java split. We haven't been able to reproduce the original problem experienced by BNL with SHA1-signed certs. Until you hear otherwise, osg-ca-certs and osg-ca-certs-java will remain as identical packages
2. Are you all still using the Frontier Squid container? It's currently running  CentOS Stream 8 and I'd like to bump it to Alma Linux 9
