Should we wait for update to new Minecraft versions for example 1.16.5? And if answer is "yes" can we have any dates?

If you're asking if you want to port the code to 1.16.x if brandon3055 isn't going to update Draconic Evolution, then no. There's no need; if you take a look at the master branch, you'll see that it's 1.16.4 already.

As for the dates, I'll tell you what I've told everybody else; Soon:tm:.
