Anyone can test with the latest version of jquery by grabbing a nightly build. http://code.jquery.com/nightlies/jquery-nightly.js
The issue is rather that plugin authors don't have the time to update their plugins right when the new version comes out. I believe there are already some plugins labeled "official". Remember that everyone here develops in their free time so placing high demands isn't a viable option. I agree that there is quite the mayhem when new versions are released and plugins must be updated, but this is true with most software with plugins, like firefox addons, or world of warcraft addons. Discussion of ways to improve this is always appreciated though, thank you. ~Sean
