Not much information given, but according to the announcement, "The OpenNETCF team has worked with the patterns & practices team at Microsoft to provide a version of the Application Blocks for the .NET Compact Framework."
You can download them here at OpenNetCF.org.
Also, "the long anticipated release of version 1.3 of the Smart Device Framework has been released." Not much info on those either, so I'm looking forward to digging around in the code to see what's going on.
