You've probably already heard about the CDN support of RadScriptManager and RadStyleSheetManager (part of the RadControls for ASP.NET AJAX suite).
Removing the need to manually edit the web.config file, the Project Management Wizard (started through the Telerik -> RadControls for ASP.NET AJAX > Convert to Telerik Project/Configure WebSite menu) now allows you to define if you want to enable or disable CDN support for each of the controls globally (website wide).
In a manner, similar to the global skin, CDN support can be enabled/disabled at control level, overriding the global setting in the web.config file. All you need is use the CDNSettings property and set its TelerikCdn attribute to the desired value. The control-dependent page templates support this setting as well:
So why would you need to wait anymore, just grab the new release, upgrade your projects and utilize CDN support!
