On November 14th was released Batteries 2.8.0, that brings compatibility with OCaml 4.06.
Batteries is a community-maintained foundation library for OCaml projects – in the same space as Base, Core, and Containers – that tries to remain compatible with the interfaces exported by the OCaml compiler’s standard library.
As always, we backported the 4.06 standard library functions within Batteries, which means that code using them through Batteries will be compatible with older OCaml versions – except for functions relying on new capabilities from the OCaml runtime. The independent project Stdcompat, announced on the same day, has the same goal of easing the use of new OCaml library functions, and I hope that we can share our efforts in the future.
