As you know, the 1.13 asked me a lot of work to update. The new communication system brought by the 1.13 was not very complicated to implement, support the old servers and the new ones at the same time asked me a little courage but it was feasible, but what was the most difficult for me was definitely supporting the cross version servers. I am pleased to announce that I managed yesterday thanks to the help of a few friends to detect the mods of a player connected in 1.12 on a 1.13 server with ProtocolSupport and a prototype of HackedServer installed.
I should have posted the update today but I had some unforeseen: in fact I use my own system for registering commands dynamically and it does not seem to be compatible with the 1.13. I was also delayed by the release of 1.13.1 (but compatibility should be quick to do this time). Sorry for taking time, I hope you do not mind me too much and you will enjoy v2.0 soon!
