Comment (by ctreleaven):

 The release notes say:

 ''As a language, OCaml 5 is fully compatible with OCaml 4 down to the
 performance characteristics of your programs. In other words, any code
 that works with OCaml 4 should work the same with OCaml 5.

 The currently known exceptions to this rule are:

 the removal of many long-deprecated functions and modules
 changes to the internal runtime API
 the performance of ephemerons is currently (and temporarily) strongly
 degraded.
 ''

 Have any problems been noted in the field in the last few months?

 I'm not familiar with Ocaml but I'm looking at updating the geneweb port.
 It would require some additional ocaml libraries be added.  I could try
 updating ocaml to 5.0.0 at the same time.
