They released a new pixelmon version for minecraft 1.16.5
Would be amazing if you are able to update this to work with that version.

Thanks you the update. Will take a look and see what I can do.

Yeah I had a look as well already and all the mods have changed. TOP, HWYLA, etc. all have completely different APIs now. And there is the problem of minecraft 1.16.5 being really different from 1.12.2
Felt to me like it will result in almost a compleet rewrite of how stuff is rendered.

Nothing like starting fresh :(
With any luck it might be easier this time around.

I have released the first version of the mod with 1.16.5 that includes Tooltips, WAILA and TOP.
Am working on JEI integration for the next version.
