- We migrated from subversion to git. To access pre-git changesets you can use our trac system that is still online. You can use this url and append the revision number to see the changelog http://sourceforge.net/apps/trac/jsxgraph/changeset/, e.g. http://sourceforge.net/apps/trac/jsxgraph/changeset/1234 for revision r1234.
