 Tools/Demos
 
+- A new script called Tools/scripts/google.py was added, which fires

 Build
 
+- Note that release builds of Python should arrange to define the
+  preprocessor symbol NDEBUG on the command line (or equivalent).
+  In the 2.2 pre-release series we tried to define this by magic in
+  Python.h instead, but it proved to cause problems for extension
+  authors.  The Unix, Windows and Mac builds now all define NDEBUG in
+  release builds via cmdline (or equivalent) instead.  Ports to
