[ANN] containers 3.3

Community

I’m glad to announce the release of containers 3.3. Containers is an extension to OCaml’s standard library that strives to be compatible with it, with more features and a few additional modules to get dynamic arrays, heaps, S-expression parser/printer, etc.

In this release, we have new support for parsing/printing canonical S-expressions (a simple binary-safe format), a code-generation module for bitfields, and many improvements to existing modules in particular in the interface between maps/set/hashtbl and iterators.

More details in the github release.

Many thanks to the contributors, in particular @Fardale for his work on CI and auto-doc-generation.

Thanks @c-cube.

I truly believe having a variety of standard libraries (Stdlib,Batteries,Containers,Core) is an asset of OCaml. It’s especially nice to see how you have done compared to how i would have do. There is still room for wanna-be standard library creators. If somebody wants to perpetuate the OCaml-Reins-way i would applause rather than cry for fragmentation.
