  3. Circles of convergence did not always update correctly when other things changed. This has been fixed.

Version 1.0

  1. Version number becomes 1.0
  2. For pre-selected functions, use "radius of convergence" to determine convergence rather than tolerance on step size.
  3. Pre-selected functions are hard coded, thus speeding up execution.
  4. Graphs of radii of convergence are available for pre-selected functions.
  5. Latest version of iter pane is used.

Version 0.9

  1. Menu bar added.
  2. Fixed bug occuring when number of orbit points pass 200.

  1. Changed some label sizes so they would show up correctly on Windows
  2. Changed color of iterations to white on fractal, black on non-fractal.

Version 0.6

  1. Added z^3-1 to drop down menu.
  2. Changed domain/range for z^2-3z+1 tp [-3,3] x [-3,3]
  3. Fixed bug on zooming via mouse wheel.

Version 0.5

  1. Removed options for circular and rectangular grids.
  2. Removed graph of range of function.
  3. Changed color scheme.
