Changes

9.3 Version
  New font settings for the graphics font, and the menu font.
9.2 Version
  The web page of C.a.R. does not use frames.
  The default font is "dialog" again, but can be changed.
  The downloads come from our server. Sourceforge is too slow.
9.1 Version
  Implemented display for rational trigonometry. Segments and circles display as quadrances, and angles as spreads.
  Function q(x) to convert distances into quadrances (returning x*x).
  Function s(t) to convert an angle t to a spread (returning sin(t)^2).
  Elements can now be displayed as fractions.
  New object: conic section from equation. Ctrl-click the quadric icon for a test. Make sure, you enter a quadratic function as the expression of the conic section.
  Conic section can now be defined by points and tangential directions in the points. Select a line after a point for this.
9.0 Version
  Moved C.a.R. to Sourceforge.
Conditional formatting for polygons.
Greek translation by Giorgos Vasilopoulos.
Ticks on segments and angles.
Invisible macro objects no longer used as job targets.
Export dialog now remembers switching off icon for macro definition.
More than one applet on one HTML page (not recommended!) works more stable now.
Unlimited colors are now possible. Enable the button for this in the icon bar, if you want to set an own default color.
Fixed zeros sets with functions which are invalid at some points.
Error from 8.82 with exp function.
Error in macro execution, when the target was a bound point, and an intersection was created.
Expressions with numbers in exponential format.
Expressions, which are macro targets, are now visible.
User functions in macros, which depend on other objects, now work as expected.
8.8 Change
The grid is now a bit lighter.
Improvements in Portuguese translation.
Translation to Thai. Thanks to Waravut  Butrat!
I had to restrict the dragging of parallels and perpendicular lines, since the side effects were too frightening.
Removed problem with the change from 8.74.
Fixed the English documentation.
List of construction elements is on by default.
Default for button "More ..." is "on".
Tried to fix problem with tooltips in dialogs under OS X.
New Dutch translation (thanks to Jan van Hee),
Colors for the applets and its shadow can now differ (parameter colorshadow). This is necessary, if the applet has a different color as the web page, and has a shadow.
Colors in applet parameters can now have the form "#FFFFFF".
integrate, diff, zero, min and max now work for user defined functions too.
8.7 Version
Improved the algorithm to compute zero sets of functions of two variables.
Problem with 1 or 3 parameters fixed.
8.6 Version
By default, applets have a shadow now (can be hidden).
Tutorial pages now have a new style.
8.5 Version
Bug, when moving a slider.
8.4 Version
RSS Feed for C.a.R.
New color selector for system colors
Expressions can be check boxes with 0/1 value.
HTML export now uses XHTML.
Small icons can now be set for applets in export dialog.
In HTML export zirkel.jar can be copied to destination automatically.
Fixed the user directory for Windows Vista.
Fixed angle size in print preview.
Warning message in non-visual mode, when the mouse is used.
Macros can be iterated.
The size of the construction area can be set in pixels.
8.3 Stable Version
It is now possible to replace objects by other objects of the same type. E.g., intersections can be replaced by free points.
8.2 Fix
Solving a job and moving objects led to unexpected behavior.
The checked job targets have now a darker color than the no checked targets.
8.1 Fix
The label export to SVG did not work, and also the new point style.
8.0 Stable
Increased the defaults for the minimal point and font size, and the line width to give constructions a better and more solid look.
Arrows with solid heads.
Points in normal thickness are now drawn on top and filled with background. This can be switched off for each point and by default.
Option to set points to a large size.
Areas and filled circles can now be filled with the background color (painted on top of other objects).
It is now possible to draw the zero set of a function in two variables. Use a user function with two variables for this.
The edit tool no longer needs the shift key. Finish with a double click.
The maximized state for the program window is now saved. The object list no longer changes the window size.
