OCaml 5.0.0 released

Version
5.0.0 of the OCaml programming language is out.

The highlight of this new major version of OCaml is the
long-awaited runtime support for shared memory parallelism and
effect handlers. This multicore support is the culmination of more
than 8 years of effort, and required a full rewrite of the OCaml
runtime environment. Consequently, OCaml 5.0.0 is expected to be a
more experimental version of OCaml than the usual OCaml releases.
