Telerik's Support Lifecycle Policy

Telerik established its Support Lifecycle Policy in order to make its support timeline for RadControls for ASP.NET AJAX clear and predictable and help customers make more accurate plans for their own products and support based on that knowledge.

Support Types

  • Mainstream Support
    Mainstream Support is the highest level of support for all RadControls. While covered by Mainstream Support, RadControls will receive full product support through all support channels, all new controls added to the RadControls suite, all product feature enhancements, all bug fixes, and free support incidents (with a current subscription).
  • Limited Support
    When a product suite enters Limited Support, it will continue to receive all bug fixes and support through all support channels. It will not, however, receive all new product feature enhancements or new controls. Only features and controls that do not depend on newer framework features will be added during Limited Support.
  • Extended Support
    Finally, when a product enters the Extended Support phase, it will no longer receive active support. Support for these products will be available on a pay by incident basis and will be available for at least 2 years after a product suite leaves the Limited Support phase.

The following chart shows the differences between the three support phases for RadControls products:


Mainstream Support Limited Support Extended Support
New products All Limited None
Product Enhancements All Limited None
Bug Fixes All All None
No-charge incident support Yes Yes No
Paid Support Included in
Subscription 		Included in
Subscription 		Per Incident

Telerik will offer a minimum of 2 years of Mainstream Support for each version of the RadControls. Once a new version of the .NET framework has been released, Telerik will offer 1 additional year of Mainstream Support for the previous framework version. After that year has elapsed, Telerik will provide 2 additional years of Limited Support for the previous framework version. Extended Support for a previous framework version of RadControls will begin 3 years after a new version has been released.

Current Framework Support

Based on this policy, this is how the current .NET framework versions are supported:
  • RadControls for .NET v2.0, introduced Q4 2005
    Current Support Phase: Not Supported   
  • RadControls for .NET v3.5, introduced Q1 2008
    Current Support Phase: Limited (began Q1 2011) 
  • RadControls for .NET v.4.0, introduced Q1 2010 
    Support Phase: Mainstream
  • RadControls for .NET v4.5, introduced Q2 2012 SP1
    Support Phase: Mainstream

This policy is effective immediately and applies to all RadControls for ASP.NET suites. Telerik reserves the right to amend this policy as required by shifting customer demand and marketplace forces.
