What’s the best reference for historical browser support/element compatibility of HTML specifications?
Specifically, I’m looking for browser versions that first gave basic support to HTML elements, in IE, Firefox, Opera, Chrome, and Safari.
The Mozilla Developer Network is a good resource; however, basic browser support of many elements in this resource are listed as ‘yes’ instead of the first known compatible browser versions. Example: The bottom ‘Browser compatibility’ table of the summary for the (Bold) element.
Other resources conflict on first supporting browser versions for various elements, and, don’t list references either. Example: Blooberry.com, an ancient (!) and popular resource, lists the B element as being first supported by IE in version 1. Aptana.com, however, lists IE 2.0 as its first version supporting .
