New Text Tool (much easier to make dynamic
texts)
Layout manager (Drag & Drop and Undock Views)
Implicit equations eg (x² + y² - 1)³ = x² y³
New CAS View
Animated GIF export
Scripting, Buttons, Textfields
Accessibility features (eg completely useable
without the mouse)
Dynamic limits for sliders & axes
Spreadsheet: Much better tracing dialog
Spreadsheet: Data analysis / chart dialog /
probability calculator / function inspector
Much better LaTeX / Equation rendering
Animation of point on
circle/ellipse/locus/compound path/etc
Transform Functions (eg Reflect[ sqrt(x), y=x ] to
show an inverse)
Style bar for quick changes of properties (color,
font size, thickness etc)
Intervals eg 3 < x < 6
New filling options: Hatching, Image
Inequalities
Two Graphics Views
Upload worksheets direct to materials manager
