Title: Change Log

1.0.0b2:
* Major improvements in memory usage:
** Merged in changes from Timo Besenruether to reuse canvas elements and improve 
   memory performance.
** Fixed all identifiable DOM leaks.
** Mergged in changes from cguillot for memory improvements in IE < 9.
* Added vertical and dashed vertical line support for canvas overlay.
* Fixed bug where initially hidden plots would not display.
* Fixed bug with point labels and null data points.
* Updated to jQuery 1.6.1.
* Improved pie slice margin calculation and fixed slice margin and pie positioning 
  with small slices.
* Improved bar renderer so bars always start at 0 if:
** The axis is a linear axis (not log/date).
** There are no other line types besides bars attached to the axis.
** The data on the axis is all >= 0.
** The user has not specified a pad, padMin or forceTickAt0 = true option.
* Modified tick prefix behavious so prefix no added to all ticks, even if format 
  string is specified.
* Fix to ensure original tick formats are applied when zooming and resetting 
  zoom.
* Updated auto tick format string so format adjusted when zooming.
* Modified auto tick computation to put less ticks on small plots and more
  ticks on large plots.
* Update bubble render to support gradients in IE 9.

1.0.0b1:
* Much improved tick generation algorithm to get precise rounded 
  tick values (Thanks Scott Prahl!).
* Auto compute tick format string if none is provided.
* Much better "slicing" of pie charts when using "sliceMargin" option to set
  a gap between the slices.
* Expanded canvasOverlay plugin to create arbitrary dashed and solid 
  horizontal and vertical lines on top of plot.
* Added defaultColors and defaultNegativeColors options to $.jqplot.config.
* Fixed issue #318, highlighter & bar renderer incompatability.
* Improve highlighter tooltip positioning with negative bars.
* Fixed #305, mispelling of jqlotDragStart and jqlotDragStop.  MUST NOW BIND
  TO jqplotDragStart and jqplotDragStop.
* Fixed #290, some variables left in global scope.
* Fixed #289, OHLC line widths hard coded at 1.5. Now set by lineWidth option.
* Fixed #296 for determining databounds on log axes.
* Updated to jQuery 1.5.1
* Fixed waterfall plot to ensure first and last bars always fill to zero.
* Added lineJoin and lineCap option to series lines.
* Bar widths now based on width of grid, not plot target for better scaling.
* Added looseZoom option to cursor so zooming can produce well rounded ticks.
* Added forceTickAt0 and forceTickAt100 options to ensure there will always
  be a tick at 0 or 100 in the plot.
* Fixed bug where cursor legend didn't honor series showLabel option.


1.0.0a:

* Series can now be moved forward or backward in stack to e.g. bring a line
  forward when mousing over a point.
* Can now move outside of grid area while zooming.  Can have zoom
  constrained to grid area or allow zooming outside.
