Does not appear to be a session-breaking update. I just updated with no ill effects.

Actually, I already provide this in the release notes. A PROTOCOL_VERSION bump means restarting tmux. We didn't do this between 1.9a -> 2.0, hence why it wasn't mentioned. Look at the release notes for 1.9, you'll see it was mentioned there. Simples.
have you tried something like tmuxinator so create/restore sessions?
May I suggest a more lightweight alternative for Tmux/Screen/DVTM sessions - http://zserge.com/blog/mucks2.html ?
Is this a session-breaking update?
I'd hate to run the update only to have it kill my current TMUX session.
Devs - if you're reading this: PLEASE indicate if I could update without restarting the session.
