 6. Various performance improvements
 
+Possible Incompatibilities:
+1. Real TLBs are now used in SE mode. This is more accurate however it could
+   cause some problems if you've modified the way page handling is done in
+   SE mode.
+2. There have been many changes to the way the SCons files work. SimObjects,
+   sources files, and trace flags are all specified in the SConscript files.
+   To see how to add your sources take a look at one of them.
+3. Python is now used to created the parameter structs that were created
+   manually before. The parameters listed in a py file are turned into 
+   a header file with the same name (e.g. BadDevice.py -> BadDevice.hh). 
+   With this change the structs can be populated automatically and the 
+   ugly macros to define and create SimObjects at the bottem of source
+   files are gone. The parameter structs also automatically inherit 
+   parameters from their parents.
