Continuing on from last year’s IE9 Minor Changes list, this post describes minor changes you can find in Internet Explorer 10 in the Windows 8 Consumer Preview.
There are many changes that I will not be covering, please do not mistake this for a comprehensive list, and please note that I'm deliberately skipping over the big feature improvements that will be discussed on the IEBlog. Improvements in IE10 that impact issues or features previously discussed on this blog can be found by searching for the tag BetterInIE10.
Without further ado, here are some IE10 Minor Changes:
You should read about the preview over on the IEBlog and in the developers guide, and try out the TestDrive Demos. You should also check out the IE10 Compatibility Cookbook to learn more about features being obsoleted or changed in IE10. Lastly, see the IE10 Web Platform Features post for a deeper look at web platform APIs.
» Fixed a bug where IE9 would incorrectly attempt to DNS prefetch the word prefetch instead of the proper hostname. «
LOL! Will you backport this fix, there is no way a site is relying on this behaviour, so it shouldn't break anything. ;-)
@Benno: Oops, that was actually a bug we fixed in IE9, not IE10. Removed.
“SCRIPT DEFER behavior is fixed and now spec-compliant. (async is also supported)”
As you know, I’d love to hear the specifics of the old behavior, in case you or one of your colleagues know, so we can fully demystify github.com/.../42 :)
Thanks for this overview!
A suggestion for another shortcut. A keyboard shortcut to move to the next feed with new content in the feed list would be very useful for keyboard users, for example the blind. When there are several feeds, it's very tedious to have to down arrow through them all.
Thank you. Such lists are highly valuable and informative. Please keep them coming for IE releases. It helps us understand why certain decisions were made.
This is still so on IE10 on Win7. XMLHttpRequest no longer fails with an “1223” error when a HTTP/204 is returned by a server.
EricLaw: I'm not sure exactly what you're saying. Do you have a test page? Is that test page in IE10 Standards mode?
re: "Use no-store to prevent resource reuse in forward/back navigations."
Doesn't work, IE still caches no matter what headers, pragmas, etc. I use.
[EricLaw] I'd love to see a repro of that. Please email me either a URL or a SAZ file. Thanks!
