Today jQuery 1.1b was released. It fixes all the bugs that were found in 1.1a and to prepare for the 1.1 final release. If you find any bugs, and please consider everything that doesn’t work after upgrading a bug, report them.
Together with 1.1b, the compability plugin was released. If 1.1 breaks any of your code due to the necessary API changes, just get the compability plugin and all should run fine. Once you made the necessary changes to switch to 1.1, you can drop the compability plugin. Again, if you spot any problems, report them as a bug, that helps to alot to get them fixed.
Have fun with this great new release.
I’ll be updating my own and the plugins I’ve worked on once 1.1 final is released. There are no compability issues, but I’d like to use some of the new features introduced in 1.1, mostly to reduce code size.
