## AI overview

Jane Street's Tools & Compilers group outlines potential work for inclusion in OCaml 4.08, including improved GADT support in or-patterns, better type propagation in let bindings, and changes related to included module items.

## Source excerpt

With the external release of OCaml 4.07.0 imminent, we in Jane Street's Tools & Compilers group have been planning what we want to work on for inclusion in OCaml 4.08. These days OCaml uses (or at least attempts) a time-based release process with releases scheduled every 6 months. We're trying to avoid rushing in changes at the last minute - as we've been prone to do in the past - so this list is restricted to things we could conceivably finish in the next 4-5 months.
