Jquery 1.3.1 Released

JQuery Team relelased a new jQuery version yesterday. There no significant changes in this new version from 1.3 version. Big features of 1.3.x versions are:

  • Sizzle: A sizzlin’ hot CSS selector engine.
  • Live Events: Event delegation with a jQuery twist.
  • jQuery Event Overhaul: Completely rewired to simplify event handling.
  • HTML Injection Rewrite: Lightning-fast HTML appending.
  • Offset Rewrite: Super-quick position calculation.
  • No More Browser Sniffing: Using feature detection to help jQuery last for many more years to come.

The full details of the release can be found in the release notes:
http://docs.jquery.com/Release:jQuery_1.3

This is a bug fix release for jQuery 1.3. You can view the full list of what was fixed on the bug tracker.

There are no significant changes in 1.3.1 from 1.3 other than straight bug fixes. If you are still using jQuery 1.2.6, and looking to upgrade, please upgrade directly to this release.

Downloading

(A Google-hosted version of jQuery 1.3.1 will be available shortly.)


If you wish to checkout the full release from the Subversion repository, you can do so by following the following instructions and checking out the source from the following location:

svn co http://jqueryjs.googlecode.com/svn/tags/1.3.1


A couple quick housekeeping notes:

Some noted in the release notes for 1.3 that we missed testing on Firefox 2, even though we still support it. This was a mistake on our part: We still support Firefox 2 and test on it prior to releases. You can see the full test suite run below.

It was also noted that Safari 2 didn’t show up in the list of browsers that we tested against prior to the 1.3 release. This is correct - we are phasing out support for Safari 2 in jQuery. Considering that Safari 2 shows no appreciable market share and has been superseded by 3 separate Safari releases (3.0, 3.1, and 3.2) we no longer see a need for significant testing against that release.

Finally, a few users noticed that we no longer provide a “packed” version of jQuery (a version of jQuery run through Dean Edwards’ Packer with Base62 encoding turned on). We did this for a couple reasons:

  • Packed scripts are significantly harder to debug (even harder than minifed scripts).
  • Packed scripts aren’t able to run on all platforms without issue (such as Adobe AIR and Caja-capable environments).
  • But most importantly: Packed scripts are slower for the user than what you would get from using just minification. This may seem counter-intuitive since a packed script’s file size is smaller than a minified script but the final load time ends up being much higher (due to the decompression step it must go through). We have some data regarding the loading performance of minified scripts vs. packed scripts, for those that are interested.

The minifed copy of jQuery that we provide, run through the YUI Compressor, should be the optimal form of jQuery to use in a production environment (served using gzipping, if possible).



jQuery UI 1.6rc5 is available. Download jQuery UI 1.6rc5 You can download the entire development bundle directly http://jquery-ui.googlecode.com/files/jquery.ui-1.6rc5.zip This includes a default theme, as well as all the test and demo files. Or you can create a customized download of individual components http://ui.jquery.com/download/ and a custom theme at http://ui.jquery.com/themeroller Be sure to grab an updated 1.6rc5 theme, if you got a theme from ThemeRoller in the last two weeks. (Also, for any users of 1.5.3, there is a link on ThemeRoller for downloading legacy themes) Compatibility with jQuery 1.3 Thank you to the many people that helped test and contribute fixes to make this release happen. We have fixed a lot of issues in the two weeks since rc4 and the most major fix is this release is compatible with jQuery 1.3 (Happy Birthday jQuery) where 1.6rc4 was only compatible with jQuery 1.2.6. From now on, we ask that 1.6rc4 is no longer used for testing. Also, from here forward jQuery UI 1.5.3 will only support jQuery 1.2.6. And jQuery UI 1.6 will only support jQuery 1.3+ Thanks for any help you can provide to ensure this release is ready and fully compatible with jQuery 1.3. Please create a ticket for any issue you find on the jQuery UI bug tracker: http://ui.jquery.com/bugs (note: requires registration) and send a note for discussion on the jQuery UI Development mailing list as well: http://groups.google.com/group/jquery-ui-dev The current schedule is to wrap up 1.6 final by the end of next week.
