| 2001-01-10 | Original Version Posted.                                       |
| 2001-03-18 | Added getSelected and get/setBehavior  that can make it behave |
|            | more like windows explorer, check usage for more information.  |
| 2001-09-23 | Version 1.1 - New features included  keyboard  navigation (ie) |
|            | and the ability  to add and  remove nodes dynamically and some |
|            | other small tweaks and fixes.                                  |
| 2002-01-27 | Version 1.11 - Bug fixes and improved mozilla support.         |
| 2002-06-11 | Version 1.12 - Fixed a bug that prevented the indentation line |
|            | from  updating correctly  under some  circumstances.  This bug |
|            | happened when removing the last item in a subtree and items in |
|            | siblings to the remove subtree where not correctly updated.    |
| 2002-06-13 | Fixed a few minor bugs cased by the 1.12 bug-fix.              |
| 2002-08-20 | Added usePersistence flag to allow disable of cookies.         |
| 2002-10-23 | (1.14) Fixed a plus icon issue                                 |
| 2002-10-29 | (1.15) Last changes broke more than they fixed. This version   |
|            | is based on 1.13 and fixes the bugs 1.14 fixed withou breaking |
|            | lots of other things.                                          |
| 2003-02-15 | The  selected node can now be made visible even when  the tree |
|            | control  loses focus.  It uses a new class  declaration in the |
|            | css file '.webfx-tree-item a.selected-inactive', by default it |
|            | puts a light-gray rectangle around the selected node.          |
| 2003-03-16 | Adding target support after lots of lobbying...                |
