- Updated the copyright notices to 2010, for the 1.9.0 release.
- Fixed bug that prevented the chaining of two attributes with different modifiers to effect a date range, such as: task ls due.after:8/1/2009 due.before:8/31/2009 Thanks to John Florian.
- All unit tests most now clean up a residual undo.data file, so the number of tests increased, but with no benefit.
- Added support for tag_indicator column. - Added support for recurrence_indicator column.
