Download Qubes OS 4.1.1

A few days ago, version 4.1.1 of Qubes OS was released. Qubes OS is a privacy and security oriented operating system. It uses security by isolation, which means that the different parts of the OS run in separate VMs. Unlike VMware Workstation and Virtualbox, for example, there is no host OS, but the VMs run directly on the available hardware. The virtualization is provided by bare-metal hypervisor Xen and the user environment can be chosen from Fedora, Debian, Whonix and Windows, among others.
