We moved our version control from subversion to Git. We also created a project page at GitHub to make it easier for you to report bugs and feature requests and to participate in the development of JSXGraph.
If you are not familiar with Git you can find a lot of good ressources on the web, e.g. http://git-scm.com/documentation and the GitHub help pages.
To access our Git repository at SourceForge use
git://jsxgraph.git.sourceforge.net/gitroot/jsxgraph/jsxgraph
See this SourceForge page for more information. To access our Git repository at GitHub use
git://github.com/jsxgraph/jsxgraph.git
or fork our repository and use your fork’s URI if you are planning to contribute to our project.
