We have just release the second service pack for Telerik Extensions for ASP.NET MVC. You can download the open source version from here. Registered users can download it from their client.net accounts. You can check the release the notes here.
The most notable change is that we upgraded to jquery 1.4. The benefits from using the latest jquery installment are quite a lot – performance improvements, lots of new features etc. We also hosted jQuery on Telerik CDN.
However this upgrade comes at a price. Be warned that this change will break your existing web site if you are using jquery-1.3.2 and you include it manually in your pages.
This (1.3.2) is the version included by the ASP.NET MVC Web Application project template and used by previous versions of Telerik Extensions for ASP.NET MVC. Since there are breaking changes between jquery-1.3.2 and jquery-1.4 we can only support the latter. In order to upgrade successfully to SP2 you need to start using jquery-1.4. So to sum it all up:
Another new feature is RTL (right-to-left) support for the grid component. You can check the online demo here.
