OPAM - A package manager for OCaml

OPAM is a source-based package manager for OCaml. It supports multiple simultaneous compiler installations, flexible package constraints, and a Git-friendly development workflow.

OPAM is created and maintained by OCamlPro.

To get started, checkout the Quick Install guide.

Versioning

For transparency and insight into our release cycle, and for striving to maintain backward compatibility, OPAM will be maintained under the Semantic Versioning guidelines as much as possible.

Releases will be numbered with the following format:

<major>.<minor>.<patch>

And constructed with the following guidelines:

  • Breaking backward compatibility bumps the major (and resets the minor and patch)
  • New additions without breaking backward compatibility bumps the minor (and resets the patch)
  • Bug fixes and misc changes bumps the patch

For more information on SemVer, please visit http://semver.org/.

It is expected than upgrade work transparently between minor releases: an OPAM binary with version x.y.z should be able to use the OCaml packages and compilers created with OPAM version x.(y-1).0
