Does Internet Explorer support pushState and replaceState?

Question

Does anybody know if Internet Explorer supports the history.pushState() and history.replaceState() methods for manipulating browser history? Considering these are just being implemented in Firefox 4, I'm not holding my breath, but does anybody know if they're coming in IE9?

Answer 1

I'm interested in this as well, actually a lot of things regarding IE 9.0, but IE9 looks promising for once. Nothing has been released as of yet, that I've read, regarding replaceState() or pushState() being included in IE 9.

IE9 has awesome hardware acceleration now. Check this

Answer 2

I've just tried the latest Platform Preview and the first Beta, and both give the error "Object doesn't support this property of method" when trying to use history.pushState(...).
