- A new ocaml-migrate-parsetree.1.4.0 was released, replacing the old
1.4.0 with new code. This was rejected by the checksum test.
Fixed by updating to the latest opam-repository.
See: https://github.com/ocaml/opam-repository/pull/15294
- The latest opam-repository pulls in mirage 3.7, which doesn't work
(`No available version of mirage-clock satisfies the constraints`), so
pin the previous mirage 3.5.2 version instead.
- Mirage now generates `.merlin`, so remove it from Git.
