About 4 days ago, many have noticed that we had uploaded another minor bugfix release to our Google Code account. While there’s, again, no new API introduced, more than 30 issues have been cleared and the codebase is growing more stable every day.
The full changelog is available here if you want to find out if a specific issue has been addressed. As with 1.5.1, updating to this version is highly recommended and likely not to break anything in your written code.
You can grab the latest release as always via the downloader or as developer package at http://ui.jquery.com/download or if you prefer, get it as latest tag from Subversion.
As a last comment, this is probably the last minor release before 1.6, which we will announce before the end of July, so watch out for a couple of awesome new components and enhancements soon!
Have a nice day,
Paul Bakaus & the jQuery UI Team
