Dear OCaml users, 

The release of OCaml 4.13.0 is expected for next week. 

Since we had a native code generation bug fix and two minor configuration tweaks 
since the first release candidate, we are publishing a second release candidate. 
If you find any bugs, please report them here: 

Happy hacking, 
Florian Angeletti for the OCaml team. 

Installation instructions 
The base compiler can be installed as an opam switch with the following commands 

opam update 
opam switch create 4.13.0~rc2 --repositories=default,beta=git+ 

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> --packages=ocaml-variants.4.13.0~rc2+options,<option_list> --repositories=default,beta=git+ 

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

opam switch create 4.13.0~rc2+flambda+nffa --packages=ocaml-variants.4.13.0~rc2+options,ocaml-option-flambda,ocaml-option-no-flat-float-array --repositories=default,beta=git+ 

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

The source code for the release candidate is also available at these addresses: 

Changes since the first release candidate 

- #10626, #10628: Wrong reloading of the x86-64 instruction for 
integer multiplication by a constant, causing the assembler to 
reject the ocamlopt-generated code. 
(Xavier Leroy, report by Dave Aitken, review by Vincent Laviron) 

+ #10176, #10632(new in rc2): By default, call the assembler through the C compiler driver 
(Sébastien Hinderer, review by Gabriel Scherer, David Allsopp and Xavier 

+ #10451, #10635(new in rc2): Replace the use of iconv with a C utility to convert $(LIBDIR) 
to a C string constant on Windows when building the runtime. Hardens the 
generation of the constant on Unix for paths with backslashes, double-quotes 
and newlines. 
(David Allsopp, review by Florian Angeletti and Sébastien Hinderer)
