I'm just curious, as we have SL5 Beta out and it's supposed to not to be released as a final version until the end of this year...
Upcoming major and minor updates to the controls will keep just into SL4 enhancement or they will have SL5 features before it gets a final release?

Hi Nohinn,

As Silverlight 5 is completely backwards compatible, for the time being we'll keep the official releases on Silverlight 4. We are definitely looking into the new beta release and at some point later this year we'll come out with a Silverlight 5 specific release. The date is not decided yet, but we will keep you posted in the blog posts and newsletters.

Regards,
Nick
