Microsoft has updated the Windows 7 beta to fix an unknown number of reliability bugs in Internet Explorer 8 (IE8), but stopped short of saying that the browser now matches the release candidate it has already delivered to users of Windows XP and Vista.
The update, which Microsoft released Tuesday via its Windows Update service, addresses a wide range of problems that the company stuck under a "reliability" heading.
"We use the term 'reliability' to broadly encompass all types of stability problems including crashes, hangs, memory leaks, etc.," said Herman Ng, a program manager on the IE8 team, in a post to the group's blog.
Ng did not tally the bugs quashed by the update, but the accompanying support document provided some general clues. According to the support document, the update resolves eight categories of problems, ranging from crashes when resizing the browser window to crashes that result when "popular third-party extensions" are used.
