+DisplayLink Ubuntu Software Release Note
+
+Version: 1.0.138
+Date: 18th August 2015
+
+DisplayLink DL-5xxx, DL-3x00 Firmware Version: 8.12.4.73304
+DisplayLink DL-41xx Firmware Version: 8.12.4.73304
+Extensible Virtual Display Interface version included: 1.0.68
+
+=============================================================================
+=============================================================================
+
+
+A. Introduction
+===============
+
+This is the second release of DisplayLink Driver Software v1.0 for Ubuntu. It provides initial, beta quality support for DisplayLink USB 3.0 devices on specific variants of desktop Ubuntu Linux. 
+
+The driver enables video support for products using DisplayLink USB 3.0 technology. Standard native ubuntu drivers provide support for DisplayLink audio and Ethernet interfaces. 
+
+
+A1. Important notes about DL5xxx, DL-3x00 and DL-41xx Firmware
+==============================================================
+
+This software release contains an embedded firmware image. DL-5xxx, DL-3xxx and DL-41xx devices will be automatically upgraded with this firmware upon connection if required.
+
+The upgrade is silent, therefore screens connected to DL-5xxx, DL-3xxx or DL-41xx devices may require a few seconds to appear when devices are connected for the first time, or after devices have been used on other platforms and OSes.

+C. Issues fixed since DisplayLink Driver Software v1.0 for Ubuntu (1.0.68)
+==========================================================================
+
+DisplayLink service component may crash on device replug (20215)
+
+For some dock products, the DisplayLink screens may not be available after machine resume from suspend. (20218)
+
+Unable to install on Ubuntu with 4.x kernels. (20367)
+
+DisplayLink service component may crash when no EVDI module is loaded. (20398)
+
+D. Supported O/S variants
+=========================
+
+This release has been prepared to be compatible with Ubuntu 14.04.2 LTS. Other variants and editions may be compatible if they meet minimum O/S requirements, but are not supported by DisplayLink.
+
+The Software contains binaries which work on Intel x86 platform (32 bit and 64 bit).
+Minimum supported Linux Kernel version is 3.16.
+Minimum supported Xorg version is 1.16.
+
+E. Release components
+=====================
+The Software consists of an open-source kernel mode driver (EVDI) with an accompanying library (libevdi), and a supporting binary application compatible with Intel x86 platform.
+Source code for the open-source components can be found at DisplayLink's GitHub, https://github.com/DisplayLink
+
+F. How to Install
+=================
+
+To install the release, from a terminal window, with root permissions use the command:
+
+sudo ./displaylink-driver-XXXX.run
+
+Where displaylink-driver-XXXX.run is the name of the extracted DisplayLink driver.
+
+The dkms framework is required for installation of DisplayLink. This can be installed with the command: sudo apt-get install dkms
+
+More detailed information on installation can be found at http://support.displaylink.com/knowledgebase/articles/615714#ubuntu
+
+G. Supported Features & Hardware
+================================
+
+This driver will support up to 2 displays connected to DisplayLink devices. More than 2 DisplayLink displays may work, but not supported or tested by DisplayLink. 
+
+Resolutions up to 4K are supported on the appropriate DisplayLink hardware.
+
+Device families supported:
+- DL-5xxx
+- DL-41xx
+- DL-3xxx
+
+Support for DL-1x5 and DL-1x0 devices is provided by the open source udl driver.
+
+H. Limitations & Known issues
+=============================
+
+A list of limitations and known issues can be found here:

+
+I. Future Development
+======================
+
+DisplayLink are open to suggestions and feedback on improving the proposed architecture and will gladly review patches or proposals from the developer community. Please find a current list of areas we identify as requiring attention below. 
+
+- In this preview release, the user mode driver service is running with root permissions. In future versions, we would like to reduce the privilege level required for this process – e.g. by using a separate low-privileged user and a separate group, to ensure the permissions needed for driving DisplayLink screens are as low as possible.
+  
+- The communication between the EVDI kernel module and the wrapper libevdi library is not access-controlled or authenticated. This could be improved in future releases, making it harder to compromise the data EVDI is sending and receiving.
+  
+- EVDI kernel module driver is currently a platform_driver, for multiple reasons; most importantly because virtual displays are not discoverable, i.e. cannot be enumerated at the hardware level. EVDI is also a generic device, not tied to any particular kind of device, transport layer or a bus.
