Microsoft changes .NET Framework Support Lifecycle Policy

On August 7, 2014, Microsoft announced that support will end for .NET Framework 4, 4.5, and 4.5.1 on January 12, 2016. We recommend customers and developers complete the in-place update to .NET Framework 4.5.2 by January 12, 2016 to continue receiving technical support and security updates. Support for .NET Framework 4.5.2, as well as all other .NET Framework versions such as 3.5 SP1, will continue to be supported for the duration of the operating system support lifecycle.

Sharepoint 2007 “Mainstream Support” ends in April 2012

Microsoft has released the third service pack for Office 2007 and Sharepoint 2007 SP3¬†¬†this is the final packs for both Office 2007 and SharePoint 2007. Both products are scheduled to lose “mainstream support” in April 2012. During the mainstream support period, users have access to free product support as well as security and non-security updates.

After mainstream support ends next April, Office 2007 and SharePoint 2007 will enter a five-year period of “extended support,” during which users can still receive security updates.
