Mirage OS is a library operating system that constructs unikernels for secure, high-performance network applications across a variety of cloud computing and mobile platforms. As such, Mirage OS is a collection of libraries and tools, as well as a development workflow. This means that any given release is a set of related libraries, intended for use by application developers, with various dependencies and independent version numbers.

All Mirage OS libraries are released via the OCaml Package Manager (OPAM), which makes it easy for developers to obtain the libraries, with OPAM managing the dependencies. To being using Mirage OS, you must first install OPAM. Once OPAM is installed, obtaining the latest release of Mirage OS is as simple as opam install mirage.

Although we do not recommend using outdated package sets, below are links on how to obtain previous versions. These outdated versions of the Mirage packages set are unsupported and we encourage all users to remain up to date. Keeping your package set up to date is as as easy as opam update, followed by opam upgrade. We recommend you do this on a regular basis to benefit from frequent bug fixes and new features.
