Dear OCaml users,

A regression has been discovered within OCaml 4.13.0 that make the compiler
crash on classes named `row`

    module M = struct
      class row = object end
    end

due to a collision between two families of internal identifiers.

To restore your freedom to name classes however you want, we have
released OCaml 4.13.1 as an early bug-fix release.

This new version is available as a set of OPAM switches with

  opam update
  opam switch create 4.13.1

and as a source download here:

Happy hacking,
Florian Angeletti for the OCaml team.

OCaml 4.13.1 (01 October 2021)
