With each new release of the .NET framework I periodically receive inquiries about updates to the P&P documentation to reflect the current release.  Today I came across the schedule of current and upcoming patterns & practices releases out on the MSDN Dev Center.  This is a relatively new addition to the P&P web site and should prove helpful in your effort to plan and adopt best practices in the design and development of your .NET applications.  The site also highlights previous releases with no plans for enhancement.  In many cases the guidance provided is either still relevant or has been subsumed in another document.
