Not a surprising move ddevault finally marked gmisrv and - more important for me - gmni, the upstream project for cgmnlm, as unmaintained. This has no immediate effect on cgmnlm, it will continue to work for the time being. But this means that we should not expect relevant contributions to upstream anymore. I'd happily review and merge patches that are submitted to me via sourcehut, codeberg or mails.
For the moment (unless someone steps up and is willing to take the effort) we are likely stuck at BearSSL - which means no TLSv1.3 unfortunately.
