Dear All, A release candidate of OpenSim 2.2. has been placed on the downloads page of OpenSim under the package name "OpenSim Release Betas", please give it a spin and send your findings to this list. As of now the release is available on Windows (and built with VisualStudio 8 Professional & VisualStudio 9 Express). Please use the download marked as beta 5. Updated linux and MAC builds of the OpenSim libraries will be available next week. For specific testing activities, I created a list of tasks, available at https://simtk.org/pm/task.php?group_project_id=935&group_id=91&func=browse Feel free to pick any subset of these and let us know so that the effort is not duplicated. Just installing the application, and trying the APIExample, plugin or trying to continue your regular use of OpenSim and reporting any issues would be a great help. The release contains primarily bug fixes and a few changes to the GUI. The User Guide has been updated accordingly. Thanks all for your time & I sure look forward to your feedback. -Ayman On behalf of the OpenSim team
