Revision 34 of the Noise spec is published at:

(Also:

and similarly for rev33, so we can track historical versions).


See the Change Log in the appendix.  Mainly we added deferred
patterns, and a lot of clarifications, including better terminology
for compound protocols like Noise Pipes / NLS which might involve
Alice and Bob negotiating and switching between simple Noise
protocols.

Thanks everyone who helped, we improved a lot of text, and have a much
stronger foundation of handshake patterns, generation rules,
terminology, and analysis to build on.

In particular, Justin Cormack did great work on deferred patterns and
pattern-generation rules, and the Noise Explorer team of Nadim
Kobeissi and Karthik Bhargavan provided invaluable analysis.
