In a May 28 blog posting, the IE team publicized "a new set of features" on which the team is working. The blog post didn't go so far as to promise that any/all of these will be in IE12 -- or whatever Microsoft ends up calling the next version of IE. But officials said the "in development" list is "an indication of what we currently have highest confidence in delivering" in the next release.
The full list of 153 features on the status.modern.ie page shows the support commitment and status of each feature or standard that the IE team has delivered, is working or has decided not to support. It also includes for each feature a list of which of the top browsers supports and/or is committed to supporting it.
In the IE blog post, officials noted there are other, so-far unspecified features that Microsoft knows "are very important" and plan to support.
The goal of the IE team with the new status page is to give developers more of a heads-up as to what to expect on the Microsoft browser front, going forward, officials said.
