Change Log Ajax Many thanks to those of you who reported bugs, and to the following people who contributed patches to the 1.9.1 release: Adam Coulombe, Andrew Plummer, Corey Frang, Danil Somsikov, Jean Boussier, Julian Aubourg, Mike Sherov, Oleg Gaidarenko, Richard Gibson, Ryunosuke Sato, and Timmy Willison. We’ve sent the files to the Google and Microsoft folks, so you should see them up on their CDNs shortly. Or, leave the plugin in place until you have the chance to fix your code and plugins to make them 1.9-compatible. Once you fix the warnings you can remove it. The plugin will quickly find and fix any compatibility issues, just look in the browser console. Please, please, please, use the jQuery Migrate plugin and look at the upgrade guide if you’re just starting your upgrade to jQuery 1.9. Whether you’re using 1.9.0 or using an older version, these are the droids you’re looking for. The jQuery team is pleased to announced that jQuery 1.9.1 is available! This release addresses the bugs and regressions that have been reported during the past few weeks.
