Dear OCaml users, 

The release of OCaml 5.2.0 is imminent. 
As a final step, we are publishing a release candidate to check that everything is in order before the release in the upcoming week(s). 

If you find any bugs, please report them on OCaml's issue tracker at https://github.com/ocaml/ocaml/issues. 

Compared to the second beta release, this release contains one small compiler-libs printer fix and one configuration tweak. 

The full change log for OCaml 5.2.0 is available on GitHub (https://github.com/ocaml/ocaml/blob/5.2/Changes). 
A short summary of the changes since the second beta release is also available below. 

Happy hacking, 
Florian Angeletti for the OCaml team. 

Installation Instructions 
------------------------------ 

The base compiler can be installed as an opam switch with the following commands on opam 2.1 and later: 

opam update 
opam switch create 5.2.0~rc1 

The source code for the release candidate is also directly available on: 

* GitHub: https://github.com/ocaml/ocaml/archive/5.2.0-rc1.tar.gz 
* OCaml archives at INRIA: https://caml.inria.fr/pub/distrib/ocaml-5.2/ocaml-5.2.0~rc1.tar.gz 

Fine-Tuned Compiler Configuration 
---------------------------------------------- 

If you want to tweak the configuration of the compiler, you can switch to the option variant with: 

opam update 
opam switch create <switch_name> ocaml-variants.5.2.0~rc1+options <option_list> 

where `<option_list>` is a space-separated list of `ocaml-option-*` packages. For instance, for a `flambda` and `no-flat-float-array` switch: 

opam switch create 5.2.0~rc1+flambda+nffa ocaml-variants.5.2.0~rc1+options ocaml-option-flambda ocaml-option-no-flat-float-array 

All available options can be listed with `opam search ocaml-option`. 

Changes since the second beta
