GeoGebra 4.2 Beta

• GeoGebra 4.2 Beta now has a Freehand Tool so that you can draw your own function and then look at function transformations eg f(2x). There are also some new commands to try (eg TriangleCenter, TriangleCubic, Barycenter, SurdText).
• Now that GeoGebra 4 has been released, we are working hard on GeoGebraWeb, so you can use GeoGebra worksheets from GeoGebra on tablets and phones. Progress is good and there should be some visible results by Spring 2012.

GeoGebra 5 Beta

• GeoGebra 5 Beta has some improvements (eg angles) and new commands (eg Cube, Octahedron) for 3D geometry.
