Dear all, It is my great pleasure to announce the release of Containers 1.0, after almost four years of development. Containers is a modular, clean and powerful extension of the OCaml standard library, under the permissive BSD license. It is designed to be efficient, light on link-time dependencies, and to complement the existing modules rather than replacing them. The core library has no dependency on unix and should be usable everywhere. Every module is independent and is prefixed with 'CC' in the global namespace. Alternatively, `open Containers` will bring enhanced versions of the standard modules into scope, along with a few modules that should exist, such as Option, IO or Int. Containers now requires OCaml >= 4.01. Containers also features sub-libraries for helping with threads, S-expressions, and some unix utilities to invoke sub-processes. I jump on the opportunity to thank the various users and contributors that helped improving the code, kept asking for better solutions, and reported bugs.
