Internet Explorer 7 Beta
Improved AJAX Support
Improves the implementation of the XMLHTTP Request as a native Javascript object for rich AJAX-style applications. While Internet Explorer 6 handled XMLHTTP requests with an ActiveX control, Internet Explorer 7 exposes XMLHTTP natively.
This improves syntactical compatibility across different browsers and allows clients to configure and customize a security policy of their choice without compromising key AJAX scenarios.
Open Search Extensions
In conjunction with Amazon.com, a set of RSS Simple List Extensions were submitted to the RSS community, and released under the Creative Commons license. Among other features, these extensions greatly simplify development of applications that interact with Open Search-compatible search providers.
RSS Platform
Provides rich functionality for downloading, storing, and accessing RSS feeds across the entire operating system, and enables more users than ever before to embrace RSS. Once a feed is subscribed to in one application, that subscription, and all the associated content, will be made available across the operating system for any application that wishes to consume it.
