    Where are the datepicker events?? These weird omissions keep happening and make the API less than useful. I also detest the fact that you have to scroll a mile and a half up and down a page to read through the various options, events, and methods. Bring back the old system!

  2. Developer log supplemental: Day 12 since the release. Still no sign of jQuery UI 1.9.1 on MS CDN. May be release numbers have something to do with the expected release time and we have to wait 191 days!? I am not sure and invited Lieutenant Commander Data to discuss the probabilities. Dev out.

  3. I just add the new version to my new project. Thanks alot for fixing the autocomplete bug. I did not notice before that there was a new version.
