Ole Larson has released a new version of Flot:
Key Changes

• Added support for putting a background behind the default legend.
  The default is the partly transparent background color. Added
  backgroundColor and backgroundOpacity to the legend options to control
  this.
• The ticks options can now be a callback function that takes one
  parameter, an object with the attributes min and max. The function
  should return a ticks array.
• Added labelFormatter option in legend, useful for turning the legend
  labels into links.
• Fixed a couple of bugs.
• The API should now be fully documented.
• Patch from Guy Fraser to make parts of the code smaller.
• API changes: Moved labelMargin option to grid from x/yaxis.

Most notably, the new packaging includes the modified excanvas script in the zip download to greatly simplify deploying with IE support.
