Yes, it is about time, and you, our users, have confirmed it in the several polls we ran on the topic. As of Q2 2013 (expected in June 2013), Telerik Reporting will stop supporting .NET2.x, .NET3.0x as well as VS2005 and VS2008. This way the small percentage of our users still using .NET2 and .NET3.0 have several months to migrate their projects to newer .NET versions (.NET 3.5 SP1, .NET4.x). Alternatively, these projects can continue to run against .NET2 or .NET3.0, but they will not be able to use newer versions of Telerik Reporting.
Why the change?
Again, it is not necessary to upgrade your .NET2 and .NET3.0 projects unless you would like to use new versions of Telerik Reporting. The change will take effect in June 2013, so you have several months to prepare. The last major version to support .NET2.x, .NET3.0x, VS2005 and VS2008 will be Q1 2013 (due in February 2013).
UPDATE 5/1/2013: Telerik Reporting will also drop .NET3.5 support as of Q2 2013.
