ovn-bgp-agent wass tagged for 0.4.0 shortly after 2023.1-release. It implements support for making BGP advertisements based on address scopes, which is very useful. Would you consider packaging 0.4.0 for antelope?
We have 1.0.0 in Bobcat https://cbs.centos.org/koji/buildinfo?buildID=51046 For Antelope I see rdoinfo has tags: antelope: source-branch: stable/2023.2 and RDO Antelope Trunk has latest ovn-bgp-agent 1.0 builds from that branch.
