The Xen Project has delivered a new version of its open source hypervisor.

Version 4.19 debuted on Thursday, billed as "a significant milestone to improve performance, security and versatility."
The performance claim rests on changes such as an increase in the maximum number of processors that Xen can be built for – from 4095 to 16383.
Safety has been improved by squashing 13 bugs identified in previous advisories and adopting more MISRA-C rules – guidelines for secure software development from the Motor Industry Software Reliability Association. If it seems strange that an open-source hypervisor like Xen cares about software standards for the automotive industry, know that embedded systems are among the project's primary goals—and consider what happens if buggy software means a driver can't brake when they're needed.
