The jQuery team has announced a maintenance release for jQuery v1.1 that addresses several issues found post v1.1. Here's the email from the project team:
“The bug fix release for 1.1 is now ready for all to use. There were a lot of weird behaviors that were discovered post-1.1 that needed to be remedied sooner, rather than later. If you were having any difficulties with the 1.1 release, please try this new release to see if your problems were solved.
It is highly recommended that you upgrade.
As always, if you have any questions or concerns with new release, please feel free to discuss it here. If you think you've spotted a bug, please add it to the bug tracker
