Enterprise Library Update - 1.0 to 4.1

I have an application currently using the 1.0 version of en-lib which I am trying to use with 4.1 en-lib. They currently use these blocks: Common, Data, Logging, Security.Cryptography, Security and Configuration. I'm still sitting with the source of both en-lib 1.0 and 4.1, trying to figure out which classes match, but that doesn't prove successful.

1) The config block seems to be missing in version 4.1, is it just split between other more specific blocks?

2) I am trying to find information on which parts of the code is just a name change question and where I need to rewrite the functionality. Especially classes that have been renamed or moved to a different location. Is there a good way to do this? Any documentation that can be used?

3) What is 4.1 solution for DBCommandWrapper and events in the Security namespace?
