New release of OpenViBE 0.8.0 "Autumn edition" is now available for download at : http://openvibe.inria.fr/?q=download

=== Overview =========================================

OpenViBE is an opensource platform that enables to design, test and use Brain-Computer Interfaces (BCI). Broadly speaking, OpenViBE can be used in many real-time Neuroscience applications.

The OpenViBE platform stands out for its high modularity. It addresses the needs of different types of users (programmers and non-programmers) and proposes a user-friendly graphical language which allows non-programmers to design a BCI without writing a single line of code.

OpenViBE is portable, independent of hardware or software targets, can run under Windows and Linux and is entirely based on free and open-source software. OpenViBE is compatible with MATLAB programming.

OpenViBE comes with preconfigured scenarios and runs already existing applications such as :
    * BCI based on motor imagery
    * P300 speller
    * Neurofeedback
    * Real-time visualization of brain activity in 2D or 3D

OpenViBE is available under the terms of the LGPL-v2+. The whole software is developed in C++. It consists of a set of software modules that can be integrated easily and efficiently to design BCI applications such as for Virtual Reality interaction.

=== What changed since 0.7.0 ? =======================

In this new release, you will find the following modifications (+ for adds, * for modifications, - for removes) :

    + Matthieu Goyat and Guillaume Lio contributed a box to join multiple signal streams in a single stream
    + Matthieu Goyat contributed an update to the Sound Player box to make it work on Windows
    + Yann Renard contributed a Brainamp Series driver using Brain Products low level API
    + We added a driver for the Emotiv EPOC
    + We implemented impedance check on the TMSi Refa driver
    + We updated the Brain Products VAmp driver to support FirstAmp8
    + We multithreaded the acquisition server for better performance and synchronization
    + We significantly enhanced drift management in the acquisition server
    + We added a driver seketon generator for driver developers
    + We restored the handball VR application for interaction from the motor imagery BCI
    + We added a box to compute the power of a spectrum frequency band
    + We added a box to rename signal channels
    + We added a SVM classifier (based on libsvm)
    * We updated the ModularEEG driver
    * We updated the temporal filter box to correct errors - should be very close to MATLAB now
    * We moved from libglade to gtk_builder allowing upgrading GTK
    * We updated windows dependencies to it++ 4.0.7, vrpn 7.26, boost 1.42, cmake 2.8.2, gtk 2.16.6
    * We updated the online documentation and tutorials
    * We updated many documentation pages
    * We fixed lots of bugs !

A more detailed list of the changelog can be found on the dedicated topic of the forum.

=== Special note =====================================

Due to licence limitations, the Emotiv EPOC driver is not included in the pre-compiled package for Windows. See dedicated FAQ entry for details about how to build this driver.

=== What's coming in the next release(s) =============

Here is a snapshot of what we are currently doing and what you can expect from the next release(s) :

    + An updated/stable Brain Products driver through Vision Recorder should be available
    + An EGI acquisition driver through AmpServer Pro should be available
    + Sample scenarios and VR demos should unable the use of SSVEP
    + Visual C++ Express 2010 will definitely be supported
    ...

=== Closing words ====================================

We want to thank Matthieu Goyat and Guillaume Lio for their contributions.
We also want to thank again all the forum and bug tracker participants who help in making the software better every day.
Feel free to join us and to contribute as Matthieu, Guillaume and
others are doing... http://openvibe.inria.fr/?q=contributions !

Looking forward to hearing your feedback, we hope you'll enjoy working with OpenViBE as we do.

Best regards,
The OpenViBE consortium

+ added individual launch scripts for linux
* updated linux-test to use individual launch scripts for linux
* updated init_env_command to configure GTK environment variables instead of GLADE
* updated win32 dependencies installation - now relies on it++ 4.0.7, vrpn 7.26, boost 1.42, cmake 2.8.2, gtk 2.16.6
* updated win32 setup installation - now relies on it++ 4.0.7, vrpn 7.26, boost 1.42, gtk 2.16.6 - cmake has been removed (was not necessary for prebuilt package)

openvibe-applications-acquisition-server :
