Hey, not sure where to ask this but can we get an update to the Ocaml compiler version?

Currently codeforces uses the version 4.02 which is ~10 years outdated at this point. The latest version is 5.2.1 but a bump to any 5.0+ version would be great.

I really enjoy using codeforces to learn new languages but this time I'm having a tough time since almost everything from the stdlib I try to use gives me a compilation error :(
