Farbtastic 1.2 was released years ago. In that time jQuery has changed creating a need for farbtastic to change as well. For example, internal logic in farbtastic was calculating the offset but changes in jQuery caused it to not calculate it accurately in all cases. Switching to the jQuery.offset method, which was added after the release of farbtastic 1.2, fixed the problem.
So, when I recently moved Farbtastic over to GitHub to continue development I created a tag called 1.3u (the u stands for unofficial) containing updates that were already being using in production sites.
The complete list of changes, from the changelog are:
- Updated style to use anonymous function wrapper per http://docs.jquery.com/Plugins/Authoring#Custom_Alias.
- Now it uses the .offset() method available as of jQuery 1.2.x.
