Hello, I have the pleasure to announce that version 0.14 of containers has been released and is available on opam. The change log can be found at https://github.com/c-cube/ocaml-containers/blob/0.14/CHANGELOG.adoc . Containers has been steadily growing and improving during the past year, with a cleaner code, many more tests, functions and more benchmarks. The documentation page (http://cedeela.fr/~simon/software/containers/) gives an overview of all the available modules. The core library, designed as an extension to OCaml's standard library, has no additional runtime dependency but base-bytes and should therefore be usable from within js_of_ocaml or Mirage; moreover, every module is independent. The mailing list for questions, ideas, and other discussions about containers is: containers-users@lists.ocaml.org . Bugs or feature requests should be submitted on https://github.com/c-cube/ocaml-containers or, for github skeptics, on the mailing list. Although the library is getting more and more stable, it has not reached 1.0 yet. It is possible that a large breaking change will occur before 1.0; namely, adding labels to many functions. Any feedback about this change is welcome. Cheers, -- Simon Cruanes http://weusepgp.info/ key 49AA62B6, fingerprint 949F EB87 8F06 59C6 D7D3 7D8D 4AC0 1D08 49AA 62B6
