You can see details of these changes on my page (DavidOrnstein).
A new NonBreakingSpace presentation has been added to allow the generation of a non-breaking space for special formatting purposes.
The ability to parser dates from strings is now available from the new method Date.InstanceFromString()
A new property (NamespaceWith) can be placed in the _ContentBaseDefinition topic for a namespace and any topics listed there will be "included" (in the same way the With property works for individual topics) on all topics in the namespace. This prevents having to put :With: in every topic that uses a common library of WikiTalk functions.
