I just added two related issues (I mentioned this on list earlier, but got
no reply)

One proposing to reserve space for future public signatures - this is to
provide early defence against man-on-the-side once public crypto gets
faster and cheaper.

And a more general proposal that adds a version count field which would
also allow for public signatures, or other extensions later on.

Kind Regards,
Mikkel Fahnøe Jørgensen

In London, we continued discussion of the Invariants document, and
confirmed the plan to issue a WGLC on it now, with the understanding that
after WGLC closes we will "park" the document until the rest of the
document set is ready for publication.

The purpose of doing so is to give a high level of confidence that the
invariants will not change, while leaving the possibility of changes open
if we find *strong* reasons to do so -- i.e., the bar for introducing
changes to the Invariants will be much higher after WGLC.

Please have a look at the document and raise any issues on the issues list
or on this e-mail list:

WGLC will end on 11 April 2018.
