pls make a 1.16.1 forge version!

First off, pestering mod developers to update is generally considered very rude. People make mods as a hobby, and constantly (sometimes multiple times a day) being asked to put in loads of work to port a mod every time vanilla updates gets very frustrating.

Second, this Issues tracker is for issues. Ender IO uses another forum to manage suggestions (http://ideas.theideawall.com/EnderIO/) where people can vote, and has a Discord for more informal questions (with your question addressed with a pinned message that Cities linked [but then deleted :P ]).

Now, to answer your request/question. No.

Ender IO will eventually be ported (the mod is Public Domain and popular), and the current developer(s) does want to port it, but porting past the 1.13+ hurdle requires weeks of full-time work for one person, and again, this is a hobby. Meanwhile, 1.16.2 is estimated to be out in a few weeks, and mods generally port to the most up-to-date version. Ender IO might get a 1.16.x release, but 1.16.1 is extremely unlikely.
