ECMAScript 5.1 Support for Opera (Snapshot Build)
To get a sense for why this is so exciting for both developers and end-users, just check out the difference in results for test262 (the official test suite) between Opera 11.51 and today's 12.00 pre-alpha snapshot:
Opera Next snapshot: Pass: 10926
|Fail: 1||Failed To Load: 0|
Opera 11.51 Final: Pass: 7062
|Fail: 3865||Failed To Load: 66|
And the one test this snapshot fails is likely invalid.
If ES5 isn't your thing, we've still been working hard on completing our support for HTML5 as well. In this snapshot the tireless Philip Jägenstedt has landed the @muted (CORE-40275) and @preload (CORE-19293) attributes for HTML5 <video>.
Finally, a fun CSS bug was fixed (CORE-28884) allowing box-shadows for <input> elements to finally work as you would expect.
Go grab the snapshot while it's still hot and be sure to check out the full changelog!
