Qubes R3.0 release notes
|
||
========================
|
||
|
||
|
||
This Qubes OS release is dedicated to the memory of Caspar Bowden.
|
||
|
||
New features since 2.0
|
||
^^^^^^^^^^^^^^^^^^^^^^
|
||
|
||
|
||
- HAL (Hypervisor Abstraction Layer) - based on libvirt, opens a whole
|
||
new possibilities of using different hypervisors. Currently Qubes OS
|
||
uses Xen.
|
||
|
||
- Xen 4.4 - many new features, but for us the most important is much
|
||
more mature libxl toolstack.
|
||
|
||
- Qrexec 3 - greatly improved performance by using direct VM-VM
|
||
connections and bigger buffers.
|
||
|
||
- Debian templates gets official support.
|
||
|
||
- Whonix templates
|
||
|
||
- Build system improvements - especially support for
|
||
distribution-specific plugins (makes supporting multiple
|
||
distributions much easier) and building templates using DispVM.
|
||
|
||
- Automated tests - makes much easier to find bugs, before its even
|
||
shipped to users
|
||
|
||
|
||
|
||
Known issues
|
||
^^^^^^^^^^^^
|
||
|
||
|
||
- Windows Tools: ``qvm-block`` does not work
|
||
|
||
- UEFI is not supported, you need to enable “legacy boot” in BIOS
|
||
before installing Qubes OS
|
||
|
||
- Some icons in the Qubes Manager application might not be drawn
|
||
correctly when using the Xfce4 environment in Dom0. If this bothers
|
||
you, please use the KDE environment instead.
|
||
|
||
- If your GPU is not correctly supported by the Dom0 kernel (e.g. the
|
||
3D desktop effects do not run smoothly) then you might experience
|
||
“heaviness” with Windows 7-based AppVMs. In that case, please solve
|
||
the problem with your GPU support in Dom0 in the first place (by
|
||
using a different kernel), or install Qubes OS on a different system.
|
||
|
||
- For other known issues take a look at `our tickets <https://github.com/QubesOS/qubes-issues/issues?q=is%3Aopen+is%3Aissue+milestone%3A%22Release+3.0%22+label%3Abug>`__
|
||
|
||
|
||
|
||
It is advised to install updates just after system installation to apply
|
||
bug fixes for (some of) the above problems.

Upgrading
|
||
^^^^^^^^^
|
||
|
||
|
||
From R3.0 release candidate
|
||
---------------------------
|
||
|
||
|
||
If you are using Qubes R3.0rc1, R3.0rc2 or R3.0rc3, just install system
|
||
updates, there is no special steps required.
|
||
|
||
From R2.0 or earlier
|
||
--------------------
|
||
|
||
|
||
The easiest and safest way to upgrade to Qubes R3.0 is to install it
|
||
from scratch and use :doc:`qubes backup and restore tools </user/how-to-guides/how-to-back-up-restore-and-migrate>` for migrating of all of the user VMs.
|
||
|
||
Users of Qubes R2 can upgrade using :doc:`experimental procedure </user/downloading-installing-upgrading/upgrade/3_0>`.
