Couple of notes on plans for the protocol document:

As Nick notes, we are hoping to publish draft-05 of the protocol document
before the interim.  I have marked a handful of PRs for inclusion in that
release:

https://github.com/mlswg/mls-protocol/milestone/2

If folks could review those PRs ASAP, that would be helpful, as we will be
working to get a few major things merged next week.  Thanks to Joël Alwen
and Michael Rosenberg for reviews so far.

In general, my thinking is that draft-05 will be a "feature release" and
draft-06 will be a "performance relase", in the following sense: In
draft-05, we're getting in a lot of the big changes to the security model
(tree hashing, common signing/encryption).  We'll try to keep these things
stable for a bit, to let some analysis get done.  While that's going on, we
can focus on issues that relate more to performance / scalability /
maintainability, such as server assist, server-initiated add/remove, or KDF
trees for application secrets.  I've already put a few issues / PRs into
the draft-06 milestone:

https://github.com/mlswg/mls-protocol/milestone/3
