I tried to upgrade to 12.1.1.
However, the latest version in the CentOS 7 repository (https://dl.packager.io/srv/rpm/opf/openproject/stable/12/el/7/x86_64) is 12.0.10.

It seems that the release to the CentOS 7 repository has failed.

Will the release of CentOS7 be supported in the near future?

centos7 support is currently broken for packaged Installations due to mismatch in a dependent package.

We are working on a fix and will announce it on the release notes once it is rehenabled
