I haven't had a chance to look at it yet, but Microsoft has released the ASP.NET MVC 1.0 Release Candidate.
Taking some of the bullets from Scott Guthrie's Post, it looks like the latest release of the MVC Framework includes:
- Add Controller Command
- Add View Command
- Ability to add and customize scaffolding templates
- Quickly navigate to controller or view
- Strongly-typed HTML and AJAX Helpers
- Bind Attribute no longer required
- IDataErrorInfo Support
- Cross Site Request Forgery (CSRF) Protection
- FileResult and File() helper method
- File Uploading Support
- jQuery Intellisense Files included within ASP.NET MVC Project Template
- Request.IsAjaxRequest Property
- JavaScriptResult ActionResult and JavaScript() helper method
