Microsoft normally make a grand announcement at their MIX conference. Last year, they launched IE8 (has it really been around for 12-months?) This year, they’ve revealed the features coming in IE9 and released a downloadable demonstration (Windows 7/Vista SP2 only).
Microsoft confirmed IE9 development in November 2009 but there were very few details. We now know more…
Microsoft adopted a wait-and-see approach to HTML5. That may have made good business sense, but HTML5 would have been a non-starter without Microsoft’s backing. The good news is that HTML5 will be implemented in IE9 — to some level at least. Importantly, the
audio tags are supported and Microsoft has been showing off H.264 video running at 720p in the browser.
Interestingly, IE9 will also support XHTML documents parsed with a mime-type of application/xhtml+xml. It’s about time.
Microsoft is making the most noise about border-radius, but IE9 will also support CSS opacity, the rgba color model, and further selector definitions. That’s great, but it’s nothing new: competing browsers have offered these facilities for many years.
IE9 will finally support SVG — Scalable Vector Graphics. They’ve even produced a great version of Asteroids to demonstrate the benefits of the format. I still don’t understand why they waited so long?
IE9 will also utilize Windows DirectX to improve browser rendering speeds.
The IE team have reaffirmed their commitment to browser standards. IE9 currently scores 55/100 in the ACID3 test but it will improve. That is far better than IE8, but let’s hope they reach the perfect score offered by competing browsers.
No specific details were announced, but the Developer Tools have been improved and there will be a new HTTP Inspector (Network tab) which captures requests and responses. Firebug, DragonFly and the webkit inspector already offer this facility if you want to use it today.
What We Don’t Know…
Microsoft has remained silent on two important issues:
- The release date. IE has settled into a 2-year schedule, so I suspect IE9 won’t be available for 12 months. That’s a considerable wait, especially if you’re eager to write HTML5-powered applications.
- OS support. Specifically, will IE9 run on Windows XP?
The IE9 Platform Preview only runs on Windows 7 and Vista SP2. The FAQ states:
Internet Explorer 9’s GPU-powered graphics take advantage of new technologies available in Windows 7 and back-ported only to Windows Vista. These technologies depend on advancements in the display driver model introduced first in Windows Vista.
It’s too early to talk about features [side-by-side installation with IE8 and XP compatibility] of the Internet Explorer 9 Beta.
The more distant the release date, the higher the probability IE9 won’t run on older versions of Windows. Despite strong sales of Windows 7, the vast majority of people still use XP — if they can’t upgrade, we’ll remain chained to old versions of the browser for many years to come.
Would you be tempted to switch to IE9? Will the new features be enough to match the competition? Is it too little, too late? Is the browser increasingly unimportant? Should Microsoft abandon browser development?
