GeoGebra Newsletter May 2012 - Markus Hohenwarter

The GeoGebra website, forum and wiki will be down for scheduled maintenance on 9th May 2012 for 9 hours at these times.

• GeoGebra Webstart should be unaffected but if necessary you can use our emergency download server
• If you need urgent help during that time, please ask at http://www.facebook.com/geogebra or send a tweet to @geogebra on twitter.

• GeoGebra 4 (version 4.0.30.0) has been released with bugfixes and Armenian as a new language

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
• New JavaScript commands to allow drawing to an Image
• 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)
