New major release of BOTCHA. You definitely should upgrade since it includes:
Easy upgrade: You should just enable Module Object Oriented Programming API (which becomes a dependency together with DBTNG and Autoload) first - and then update code to new version. There are no database structure changes since 6.x-2.0 and only a few database content changes since 6.x-1.10. So it would be as easy to upgrade as just a few clicks.
Selenium-tests for all major browsers (Firefox, Google Chrome, Opera, Internet Explorer plus possibility to extend): It means that JavaScripts-recipes work as expected - always, guaranteed. If you see something strange - you could just launch all Selenium-tests to see what's wrong and post an issue to Drupal.org. Brief Howto-instruction (both installation and usage of Selenium) is inside the Selenium-tests file.
