jQuery 1.11.0/2.1.0 Beta 2 Released
The latest betas of jQuery 1.11 and 2.0 have arrived! You can get them here:
Don’t forget that jQuery 1.x supports IE 6/7/8 and jQuery 2.x does not.
What’s in the beta
Asynchronous Module Definition (AMD): The biggest change in 1.11/2.1 continues to be AMD. jQuery has supported having the library itself loaded by an AMD loader ever since version 1.7. Now, we’re using AMD internally as well, replacing our old modular build system. If you want to know more, read the README file.
Published on npm: The 2.x branch of this beta and all our future 2.x releases will be published on npm so that you can use it with node or packages like browserify. Note that the main jquery page is currently not up to date, and won’t be until we push the final 2.1.0 to it. If you want to install the beta, you can use
npm install email@example.com. Many thanks to Domenic Denicola who has already reported bugs #14548 and #14549 that will be fixed in the next go-round.
Performance: Our new “lazy feature detects” reduce the startup time for the library, which is especially good for mobile devices. If you never call the API, you never even need to run that code! We also found and removed some situations where jQuery unnecessarily forced a page layout to occur.
Bug fixes: Lots and lots of bug fixes are in this release, including several to ensure the latest versions of browsers like IE11 work smoothly and eliminate console warnings in Chrome. Many fixes are shared across both versions. You can see the complete changelog below.
Please do give these betas a try and let us know whether everything is working as you’d like. It’s always frustrating to us when we make a new production release and people find bugs that could have been fixed during the beta process. It only takes a few minutes to smoke-test your code against these betas, and it will save both you and us a lot of future heartache!
Sad sourcemap story
One of the changes we’ve made in this beta is to remove the sourcemap comment. Sourcemaps have proven to be a very problematic and puzzling thing to developers, generating scores of confused questions on forums like StackOverflow and causing users to think jQuery itself was broken.
We’ll still be generating and distributing sourcemaps, but you will need to add the appropriate sourcemap comment at the end of the minified file if the browser does not support manually associating map files (currently, none do). If you generate your own jQuery file using the custom build process, the sourcemap comment will be present in the minified file and the map is generated; you can either leave it in and use sourcemaps or edit it out and ignore the map file entirely.
We will be encouraging browser makers to come up with better ways to handle sourcemaps for situations like jQuery’s, where there are widely distributed files on CDNs. We’d like sourcemaps to be robust and gracefully handle situations like file renaming or missing files. See our bug ticket for more information.
