GeoGebra 4

• We have fixed some bugs and improved the translations in GeoGebra 4. If you have the installed <http://www.geogebra.org/installers> or  portable <http://www.geogebra.org/portable> version, you may want to upgrade to the latest revision. 
• The Translation Tool<http://wiki.geogebra.org/en/Translate_Object_by_Vector_Tool>now allows you to just drag to clone an object!
• For network administrators, we now have an MSI Installer for GeoGebra 4<http://code.google.com/p/geogebra/downloads/list?can=2&q=4.0+msi>available for testing 

GeoGebra 4.2 Beta

• GeoGebra 4.2 Beta<http://wiki.geogebra.org/en/Release_Notes_GeoGebra_4.2>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 GeoGebraTube on tablets and phones. Progress is good and there should be some visible results by Spring 2012. 

GeoGebra 5 Beta

• GeoGebra 5 Beta<http://wiki.geogebra.org/en/Release_Notes_GeoGebra_5.0>has some improvements (eg angles) and new commands (eg Cube, Octahedron) for 3D geometry.
