Error installing coq-itree 5.1.1 with coq 8.18.0

[RalfJung]

In updating all my opam switches to Coq 8.18.0, I encountered what I think to be an incompatibility of coq-itree with the latest coq version. The opam file of coq-itree does not declare a conflict with Coq 8.18, but the build fails:

- File "./theories/Events/FailFacts.v", line 106, characters 6-16:

Would be nice to get an opam release of this package that is compatible with the latest Coq. :)

I found this commit which I presume fixes the problem: https://github.com/DeepSpec/InteractionTrees/commit/eede8c539985e358e7149ab77b5c058def37571d So looks like all that's missing is a new opam package that includes the fix?

I've just released 5.1.2 with that fix.

Thanks. :)
