ACRN v1.0.2 (November 2019)¶
We are pleased to announce the release of ACRN version 1.0.2. This is a maintenance release based on the v1.0 branch that primarily fixes some potential security and stability issues discovered after the v1.0 release.
ACRN is a flexible, lightweight reference hypervisor that’s built with real-time and safety-criticality in mind and is optimized to streamline embedded development through an open source platform. Check out Introduction to Project ACRN 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 v1.0.2 GitHub release page) or use the following Git clone and checkout commands:
$ git clone https://github.com/projectacrn/acrn-hypervisor
$ cd acrn-hypervisor
$ git checkout v1.0.2
There were no documentation changes in this update, so you can still refer to the v1.0-specific documentation found at https://projectacrn.github.io/1.0/.
