Microsoft announced that they will automatically update users to the latest version of IE if they have automatic updates turned on (this is a change from before where people had to explicitly accept the update instead of it happening in the background). Firefox and Chrome already do the same thing.
However, I know that one of the big reasons people have not upgraded their browsers has been policies put in place by their organizations which likely will not change.
How does this change the browsers that we should target for testing, or does it? Should we continue to test older versions until we get the latest browser market share numbers after the change goes out via Microsoft update? I am anxious to lay to rest the testing of products on older browser versions, but I don't want to jump the gun. When will we know the time is right?
