update to newer versions of ocaml ?

Hello,
I'm looking with interest at this project. Do you plan to update it with 4.06 or 4.07 ?
Do you think it's easy, or there are some technical problems that make 4.02 a better target ?
I'm a bit of a newbe in the android arena ...

thank you !

The issue names no files, tests, or entry points; start by reviewing the project setup and locating its current OCaml 4.02 references. Check the feasibility of targeting OCaml 4.06 or 4.07 for Android, and consider the work complete when the compatibility outcome and required update scope are established.
