Versions	Changes
5.2	Stable Version
	You can now use $...$ in parts of lines, even several times.
	Improved the English in the context documentation.
	Tutorials in English now.
	Korean translation of the GUI.
	Improved accuracy of intersections with conic sections.
5.1	Stable Version
	Intersections with circles can now be set to switch each time the intersection becomes invalid.
	The movement with the move tool can be restricted until some intersection becomes invalid. This can be set the default behavior for applets.
5.0	Stable Version
	Simplified the web pages to gain usability. New translation of the English documentation and examples.
	Automatic track objects can be drawn as discrete points no. The color and thickness of the points is taken from the tracked point at each position.
4.9	Stable Version
	Due to a probable error in Java intersections could have been computed very slowly.
	Macro comments now appear in the macro selection dialog. The comments can be changed when renaming the macros. Macros are now sorted when the construction is saved.
	Polished up elliptical and spherical geometries.
4.8	Stable Version
	Tracks can now be generated by sliders of expressions. Moreover, points on objects are now automatically moved on these objects.
4.7	Stable Version
	It is now possible to zoom with the mouse wheel, and to drag with the right mouse button.
	Points can be set on conic sections, and conic sections can intersect with other objects.
	Improved the performance of intersections.
4.6	Beta Version
	By default larger and better icons.
	Improved display of points and lines.
	Improved speed of tracks.
4.5	Stable Version
	Fixed the update of texts.
	Speed up objects lookup.
4.4	Stable Version
	Parameter points with self references, that are to be used in macros, must be selected with the shift key. Otherwise, the parameter point becomes a plain point in the macro.
	Settings of sizes in one dialog.
	Default setting for restricted or unrestricted intersections.
4.3	Stable Version
	Improved LaTeX output with the option, to let LaTeX draw the strings.
4.2	Stable Version
	PNG can now create bb files for LaTeX.
	Many improvements in the documentation.
	Expressions can be set and shown with sliders.
	When the grid is on, objects can snap with left mouse drag instead of right mouse drag.
4.1	Stable Version.
	Permanent object list on the left of the construction display.
	Improved automatic track objects.
	Improved computation of intersections with automatic tracks.
	New function "simulate".
	Language can now be changed with a menu entry. Options menu split in two menus.
	Macros can be organized in folders.
	Changes and improvements for macros that use other parameters than points.
	Improved self reference of objects.
4.0	Stable Version.
