GeoGebra 4.2 News
- The Python View will soon be removed from GeoGebra 4.2 beta, so you will need to use GeoGebra 5 Beta if you wish to continue using it, like the new Turtle object in Python
- Alt-drag on a parabola to rescale it leaving the vertex unchanged
- New commands: ShowGrid, ShowAxes, SetTrace
- Export images (PNG, SVG, etc) from the command line using --export and --dpi
- The Input Bar will ignore accents when matching command names (eg. 'De' will match the command 'Dérivée' in French)
