OpenSim Beta Testers - We need your help testing the new release of OpenSim - version 4.0. Even testing just one or two tasks is a big help to us. The new release is a major upgrade. OpenSim 4.0 includes a new visualizer and support for Mac OS X. For Matlab, Python, and C++ users, the API upgrades include new methods to extract results from models/simulations and a new data interface that makes it easier to get data in and out of OpenSim. We created a google doc that lists a variety of testing tasks, including the new features to try out. Please review the instructions, register, choose some tasks by marking your name in the sheet, and report back on the doc. You can also try out the new release with your own research workflow and report any bugs on the "Bugs" sheet. Beta Testing Tasks <https://docs.google.com/spreadsheets/d/1KwSPxfK3TvWH2Nfh2pA04YNr9Tf7pex2JnF6Xs24YdI/edit#gid=9> You can find the beta of 4.0 on the OpenSim downloads page.
