The Hypervisor is developed by a world-wide community of individuals, researchers and employees of companies and that follow the Xen Project Governance process based on openness, transparency and meritocracy. The project is supported by the Xen Project Advisory Board made up of project member companies that fund the Xen Project. You can find a recent contribution breakdown in the Xen Project 4.5 and Xen Project 4.4 Contribution Acknowledgments.
Introduction to the Hypervisor
What's in Xen Project 4.5
In 2015, we released Xen Project 4.5.0. You can find more information on Xen Project 4.5 in the Feature List, Release Notes and Man Pages. Xen Project 4.4 software can be downloaded from the Xen Project 4.5 download pages.
Xen Project 4.5 Features and Futures
Xen Project Releases are developed on a 9 months release cadence and follows the process outlined here.
Support for ARM CPUs
With the introduction of virtualization extensions on ARM processors, the Xen Project has added support for newer ARM CPUs to the Xen Project Hypervisor (the first release with ARM support was Xen 4.3). This port is developed and maintained by the Hypervisor team, and developed in the Xen mainline and the upstream Linux kernel. You can find information related to this work on the wiki.
Originally ARM support for newer CPUs was designed for Servers. However, recently we have seen interest for Xen Project on ARM used on Mobiles, Tablets, for Automotive applications, Middlebox Processing (Firewalls, NATs) and other Embedded applications.

Getting the Hypervisor
Sources for Xen Project Binaries
You can get recent binaries as packages from most Linux and Unix distributions, both open source and commercial. Some Linux distributions deliver Xen Project software as a LiveCD, that you can use to easily test the hypervisor.
