Hi Jorge,

You could use "emacs-next" which is fairly recent.
If that's not enough, then you can easily define your own Emacs package
just like emacs-next, but specify which version you want.

From there, all Guix Emacs packages should work out of the box.

Let me know if you need help writing a package!

Cheers!
