Microsoft dodged questions at the Mix07 Web developer conference about when it plans to update its Internet Explorer (IE) browser to Version 8.
During a session on the development of its current browser, IE 7, Chris Wilson, Microsoft's platform architect for Internet Explorer, wouldn't name a timetable when asked about a commitment to more frequent updates. He slipped past the question by saying, "I don't see another time when we go another five years without an upgrade".
Microsoft essentially shut down Internet Explorer development after it rolled out IE 6 in August 2001; IE 7 went final five years and two months later.
"It's a challenge," Wilson said. "Some want us to update in every service pack, or even in the monthly security updates, but that makes a moving target [for developers]."
At last year's Mix event, Microsoft suggested that IE would be refreshed every 12 to 18 months. However, Wilson said that every two years would be more likely. "There's no exact date," he said, "[but] your expectation of having a new browser platform every couple of years is a valid point." Two years from IE 7's October 2006 release would put IE 8 on track to appear in the fall of 2008.
Microsoft was criticised for the long gap between IE 6 and IE 7, with most analysts citing the lack of an update as one reason why Mozilla's Firefox browser has been able to steal about 15 percent of the market from IE.
Wilson also refused to spell out specific changes planned for the next IE. "I'm not going to show you a feature list, because I'm not allowed to," he said.
One change that sounded definite would be to require web site developers to "opt in" to IE's standards mode. "We have to balance compliance [with standards] with site compatibility any time we change IE," he said. "We have to come up with approaches to solve this problem."
