I have just released SleekTabs 0.2.1.
Nothing too exciting, unfortunately, just a bugfix release for a bug which would cause the ajax URLs of a tab not to work if they contained an extra ‘/’ character. This bug was a problem with a regular expression used to append a timestamp variable to the ajax URL (which itself is a fix for a bug with IE caching).
As always, you can download the script from the SleekTabs project page or from its home on PHP Classes.
