*	cache heads	tv	16 hours	7	-24/+61
\| \| \| \|	To reduce the number of write locks, heads are now cached.

*	being caught up needs some heads	tv	17 hours	1	-5/+9
\| \| \| \| \| \| \| \| \| \| \|	A sync message from a ready peer only completes the initial sync if that peer has at least one head. A peer with an empty document can no longer make a joiner ready on an empty store: a misconfigured second swarm, or a genesis node in its first seconds. Effect on a brand-new swarm: a joiner now waits until the genesis node has registered itself in the member list, which happens within about 5 s of it becoming ready.

\| \| \| \| \|	It wasn't used before, causing the supervised daemon to always pick a random one.

\| \| \| \| \|	For an upcoming change in remake coordination, nodes now maintain their self-assessed liveness in the document.

\|
*	add traffic counter	tv	30 hours	9	-12/+270
\| \| \| \| \| \| \| \| \| \|	This introduces a new wrapper that counts messages and payload bytes per peer, split by kind (hello, helloReply, sync, ping, pong), each sent, received and refused. The traffic counter goes around the firewall, which means messages dropped outbound are still counted as sent, and messages dropped inbound don't count as received.

\|
*	pull missing changes	tv	31 hours	7	-5/+162
\| \| \| \| \| \|	Nodes push changes to their neighbours but don't relay them directly. In a partial mesh, nodes can learn about missing changes via keepalive messages and can pull them from their neighbours.

\|
*	use nonce in handshake	tv	33 hours	5	-2/+39
\| \| \| \| \|	To prevent stale hello replies to cause joins and thus stale sessions, each run gets a random ID, which used as nonce in the handshake.
*	drain queued messages on startup	tv	33 hours	1	-2/+48
\|
*	consolidate backoff code	tv	33 hours	4	-49/+99
\|
*	retry using fresh messages	tv	33 hours	3	-170/+180
\| \| \| \| \|	Don't store encoded messages but retry using a newly generated one. That way any accumulated changes can be delivered at once.
*	heal from noticed divergence	tv	33 hours	1	-6/+27
\| \| \| \| \|	Wait 2*keepalive but at least 20 s to trigger resync so that lost messages can be resent first.
*	heal after reply timeout	tv	36 hours	1	-0/+3
\|
*	drop stall breaker; resend needed changes	tv	36 hours	2	-82/+21
\| \| \| \| \| \|	The stall breaker was superseded by regular re-handshaking Re-handshaking also gets triggered, when a node needs some of the heads its peer believes it has already sent. In that case the peer now resends what's needed.
*	no heal during catch-up	tv	37 hours	1	-1/+6
\|
*	peers that just became ready get syncs	tv	37 hours	1	-0/+9
\| \| \| \| \| \|	When keepalive says ready and we didn't have taht on record before, the peer is queued for sync. Hello and hello reply don't do this because the handshake already queues a sync.
*	both sides may open sync after reset	tv	37 hours	6	-163/+64
\| \| \| \| \| \| \| \| \| \|	Ready nodes will leave the first message to the pear that isn't ready. Hello and hello reply now carry ready, so readiness is known from the very first contact, before any sync. Together with the sync messages and keepalives, reports_ready is always current. After epoch switch, pings go to everyone except ready members already on the new epoch, these learn from the lagging peer's opening.
*	perform handshake in one round trip	tv	37 hours	6	-85/+74
