Inspecting the changes manually (rather than applying them
locally):

The change to NEWS should be an extra entry to say that
functional was renamed to functools for alpha 3 rather than
changing the earlier entry to say functools.

I suggest providing the what's new changes as a separate
patch - AMK may prefer to make his own changes to that area
of the docs.

I believe an update to the dependencies file for the Library
Reference is currently missing.
