According to this post, IE7 will have a native
XMLHTTPRequest object which will not require ActiveX to be enabled (after all my hard work writing a workaround for IE6 and IE5!) – this is great news for those of use who are excited about AJAX.
Other interesting fixes include a rebuilt
<select> box which allows elements to be layered over it, and a web developer toolbar (probably heavily influenced by Firefox’s webdev toolbar).
