The Xen Project has decided to support all releases of its flagship hypervisor for five years, and one of the first beneficiaries of the change is Citrix, which has delivered a preview of XenServer 9 – the release that will take the product back into the mainstream virtualization market.

We’re a bit late with this news because the sources buried it in obscure places.

The Xen Project’s announcement appeared on the xen-devel mailing list, a forum in which developers discuss deeply technical matters. It took six days before a project participant cross-posted it to xen-announce, the list for announcements.

Enough of our griping: The announcement states that the project’s Committers and Core Maintainers decided to update the Xen Project stable branch support policy “to better align with common industry expectations for long-term security maintenance.”
