I've added guix-devel to the cc: becasue the Emacs upgrade has come up a
few times on IRC, and there are ways for you to help move this upgrade
along. Any suggestions are welcome, but in particular, you can help with
the following:
* Review the inputs and configure flags. Are there any additional changes
needed for the new Emacs version? A good place to start with this would be
the Emacs NEWS file. It's quite lengthy, so additional eyes would be quite
helpful.
* Making sure packages build and work with Emacs 27.1. I expect this to
involve elisp hacking and working with upstream.
I have the following updates, since I prepared at patch for the 27.1
release candidate:

Hi Guix,
Now that there is a release candidate for Emacs 27.1, I started working on
updating our Emacs packages.
Now that Emacs 27.1 has been released, I've updated the patch for released
version. Per Michael Rohleder's (mroh) suggestion on IRC, I have added gmp
as an input.
Is the emacs-wide-int variant needed with the new multiprecision
functionality?
For the most part, it went smoothly, but there are some other packages
that broke after updating Emacs. Of the packages reported by `guix
refresh -l emacs`, the following had issues:
