I can confirm that I have abandoned all OCB patents
and placed into the public domain all OCB-related IP of mine.
While I have been telling people this for quite some time, I don't
think I ever made a proper announcement to the CFRG or on the
OCB webpage. Consider that done.

I hope people will use the scheme to do positive things.
