ACRN v0.6 (Feb 2019)
####################
We are pleased to announce the release of Project ACRN version 0.6.
ACRN is a flexible, lightweight reference hypervisor, built with
real-time and safety-criticality in mind, optimized to streamline
embedded development through an open source platform. Check out the
:ref:`introduction` for more information.
All project ACRN source code is maintained in the
https://github.com/projectacrn/acrn-hypervisor repository and includes
folders for the ACRN hypervisor, the ACRN device model, tools, and
documentation. You can either download this source code as a zip or
tar.gz file (see the `ACRN v0.6 GitHub release page
<https://github.com/projectacrn/acrn-hypervisor/releases/tag/v0.6>`_ or
use Git clone and checkout commands:
.. code-block:: bash
git clone https://github.com/projectacrn/acrn-hypervisor
cd acrn-hypervisor
git checkout v0.6
The project's online technical documentation is also tagged to correspond
with a specific release: generated v0.6 documents can be found at
https://projectacrn.github.io/0.6/. Documentation for the latest
(master) branch is found at https://projectacrn.github.io/latest/.
ACRN v0.6 requires Clear Linux OS version 27600 or newer. Please follow the
instructions in the :ref:`getting-started-apl-nuc`.
Version 0.6 new features
************************
**Enable Privileged VM support for real-time UOS in ACRN**:
Initial patches to enable a User OS
(UOS) running as a virtual machine (VM)
with real-time characteristics, also called a "Privileged VM". We've
published a tutorial :ref:`rt_linux_setup`. More patches
for ACRN real time support will continue.
**Document updates**: Several new documents have been added in this release, including:
* :ref:`Running Automotive Grade Linux as a VM <agl-vms>`
* :ref:`Using PREEMPT_RT-Linux for real-time UOS <rt_linux_setup>`
* :ref:`Frequently Asked Questions <faq>`
* :ref:`An introduction to Trusty and Security services on ACRN
<trusty-security-services>`
* A Wiki article about `Porting ClearLinux/ACRN to support Yocto/ACRN
<https://github.com/projectacrn/acrn-hypervisor/wiki/Yocto-based-Service-OS-(SOS)-and-User-OS-(UOS)-on-ACRN>`_
* An `ACRN brochure update (English and Chinese)
<https://projectacrn.org/#code-docs>`_
