Thanks!

Any idea of what's up with the 3 tuareg revdeps failures?
tuareg.2.0.10 (failed: void-function (batch-update-autoloads))
tuareg.2.1.0 (failed: void-function (batch-update-autoloads))
tuareg.2.2.0 (failed: void-function (batch-update-autoloads))

Thanks Jan. I have no idea about the Tuareg failures. I don't expect them to be related to this release.

I think tuareg is an issue with updated emacs. The rest looks good

Suggested change

	"menhir" {dev & >= "20201216"}
	"menhirLib" {dev & >= "20201216"}
	"menhirSdk" {dev & >= "20201216"}
	"menhir" {with-dev-setup & >= "20201216"}
	"menhirLib" {with-dev-setup & >= "20201216"}
	"menhirSdk" {with-dev-setup & >= "20201216"}

Are these dev (pinned package) dependencies or a good to have for development time?

[voodoos]

Menhir is indeed a dev dependency. Building in dev mode requires it (while building in release mode doesn't).

Having the correct version of menhir is a "good to have for development time" dependency, since it won't create diffs for the generated parses.
