EJS 4.3.7 release at 120920 includes some minor bug fixes.

It also features a color coding scheme for 3D bodies in the Simple3D implementation. See attached zip with example and image.

For Mac users, there is a new per-simulation option to display menu items using the top Mac bar, as in all mac os applications.

There is support for Moodle. That is to embed EJS simulations in a Moodle course, by using a specil plug-in. See moodle-mod_ejsapp at https://github.com/UNEDLabs

There is also a new, kind of experimental, view element for augmented reality that I need to experiment and document a bit more.

There is a new, still growing family of hardware model elements to control hardware Phidgets. See http://www.phidgets.com

Though it was already in a few earlier releases, it also implements the possibility of running simulations in real time, by specifying a time variable that should be synchronized with the computer time. See the Evolution panel.

As much as I can remember, that is all!

EJS 4.3.2 adds a new Model Elements workpanel.  This workpanel contains palettes of objects such as statical packages and I/O tools that can be instantiated by dragging and dropping into the model.  A Java interface is available that allows experienced programmers to build their own Model Elements.

EJS Version 4.2 adds new ODE solver algorithms and ODE zero-crossing events.  All user interface actions when running a model are now collected and processed at the end of the Evolution step to avoid data synchronization errors.

EJS 4.1 was released November 21, 2008.  

Version 4.1 improves and simplifies the drawing 2D API by allowing the user to apply an affine transformation, such as rotation and shear, to 2D Elements.  In addtion, 2D Elements can be grouped to form compound Elements and these compond Elements can be transformed.
