I did some more testing for 1.12 over the weekend and updated a good dozen plugins to the latest version on a test server. It seems that we are able to switch to 1.12 without any issues and all functionalities being ported over without issues. I found one small plugin that we use on the /home command has a small but critical issue and we are working on a new version there as well.
Once we have that, we should be ready to upgrade anytime. So please be a bit more patient.
