During the development from 0.16.2 to 0.17.0, OpenVIBE changed its repository from svn to git. We have tried to keep the side effects of this transition to the minimum.

Please find below the most significant changes. For full logs of all changes, refer to the git log.

Upgrading from v0.16.x
- Old custom configuration files are NO LONGER read from $HOME/.openvibe* on Linux or %USERPROFILE%/.openvibe* on Windows. These old locations were used by 0.15.0 and earlier. Since 0.16.0 version, the new locations of the configuration files are $HOME/.config/openvibe/ on Linux and %APPDATA%/openvibe/ on Windows. Running openvibe applications in 0.16.0 and later will read/write configuration from/to these new locations. If you wish to keep your configurations from the previous locations, you will have to move the files manually. In most cases the simplest thing to do to avoid issues is simply to delete the old configurations.
- Due to the new way of storing driver settings in the Acquisition Server, some old .conf tokens are no longer read by the server, and you may have to respecify such settings in the GUI (e.g. Emotiv EPOC SDK path).
- A few boxes have been moved to another category in the Designer box list.

Bugfix release v0.17.1 is out and available from the download page. This patch version has the following changes:

- External application launcher was not working if the install path contained spaces, preventing some stimulators (such as SSVEP) from running. Fixed.
- Fixed bugs in Brain Products ActiChamp driver. Patch contributed by Mensia Technologies. (some issues may still remain, see viewtopic.php?f=10&t=9214&p=13584#p13584 )

For the ActiCHamp you will have to also follow this simple procedure:
  • Go into openvibe installation folder (default should be something like C:/Program Files (x86)/openvibe)
  • Go into the folder bin
  • Copy the file ActiChamp.bit
  • Go back one folder level up (into the root installation folder)
  • Paste the file
