Hello! Thank you for publishing these updates. The only relevant CI failures I am seeing is

Do you intend to support this architecture, or should we mark it as unavailable?

(There is also a windows failure, but that originates in the conf-gsl package, which is not being added here.)

[mmottl]

There are currently no plans to add support for this architecture. You can mark it as unavailable. Thanks!

Thanks! You may want to announce this on https://discuss.ocaml.org, where we have a Community category and an announce tag for this purpose.
