jQuery 1.7 RC2 Released

Posted on by

Today, after a very scary Halloween, the jQuery team is releasing jQuery 1.7 RC2 from our Github crypt, er, repo. Barring a report of really terrifying problems or a mob of townspeople at our door with torches, this code will be exactly the same code that becomes the version 1.7 final. If anyone knows of any reason why this code should not become a final release, we need to hear you scream!

HERE LIE THE
BITS FOR RC2;
PLEASE TELL US
IF IT WORKS
FOR YOU

In RC2, we fixed a tricky problem that sometimes caused Internet Explorer 8 to go full-zombie when jQuery was loaded. Appropriately enough, the crash was related to creating a detached <body> element that we were using to perform feature detection. IE8 seems frightened to a crashy death when it sees a detached body. If you still see any problems with IE8 crashes, please let us know.

Thanks to a bug report from @warrenparsons, we also fixed a frightful regression with the .show() method. We really appreciate the efforts from those of you who are testing these pre-release versions. Sure, it’s a lot easier to think, “I’ll try it when it’s finally released,” but then any problems you do find will be preventing you — and possibly hundreds or thousands of others — from upgrading. Now that is really scary, at least to us.

During the next day or so we’ll be conjuring up documentation for many of the 1.7 additions and improvements on api.jquery.com. Please bear with us for a few days while we clean up the pages and make sure that it is filled in and all linked properly. For a quick overview of what’s changed, see the 1.7 category.

    What’s in Line 1621:
    container.style.cssText = vb + “width:0;height:0;position:static;top:0;marginTop:” + conMarginTop + “px”;

    What is marginTop?
    Firefox throws a warning.
    Should it be margin-top?

  2. Michael on said:

    Do you guys have a series of tests written that you run on different browsers before each release?

  3. @John, please report issues like that to Highcharts with a test case and we can resolve them by working with the plugin maker.

    @Kissifrot, IE6/7/8 share common issues so it wouldn’t help until IE8 support can be dropped. Maybe 2021 or so.
