Thanks again for your interest.
We are sorry, but when we said Spring, we did not mean our Q1 release getting ready for download today, but "Spring" which means some time during April, May or June. So current plans are to have it in one of our Q1 Service Packs.
We will update our Q2 Roadmap in the beginning of April.
There is no way to do it on your own.
Thank you for your understanding and patience.
All the best,
the Telerik team
