So:

I am currently working on the update for 1.13, but as there have been some big changes this will take a few more weeks.

But there's also a little problem.
Because of all these 1.13 changes I have to split this plugin into two versions, one for 1.7 - 1.12 (this version will only get bug fixing updates) and one for 1.13+ (with new content updates) server.

I hope this will give me more time to focus on new content updates for the plugin.
