*	bound stable-hub degree	tv	19 hours	1	-4/+46
\| \| \| \| \| \|	Each stable member can be preferred at most by 4*k members. The budget is spent in key order, which is the same on every node, so the graph stays deterministic, symmetric and connected.
*	coalesce announcements	tv	20 hours	3	-2/+60
\|
*	cache heads	tv	20 hours	7	-24/+61
\| \| \| \|	To reduce the number of write locks, heads are now cached.
*	corroberate newer epochs	tv	20 hours	1	-11/+53
\|
*	follow and download from ready members only	tv	20 hours	3	-3/+29
\|
*	being caught up needs some heads	tv	21 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.

\|
*	wire up --mycelium-tcp-listen-port	tv	25 hours	1	-2/+5
\| \| \| \| \|	It wasn't used before, causing the supervised daemon to always pick a random one.
*	introduce majority voting on remakes	tv	27 hours	7	-95/+406
\|
*	add electorate	tv	27 hours	3	-8/+109
\| \| \| \| \|	For an upcoming change in remake coordination, nodes now maintain their self-assessed liveness in the document.
*	aliases are not in logs (fixup)	tv	27 hours	2	-2/+2
\|

\| \| \| \|	GET /admin/stats to retrieve all stats.
*	add swarm stats	tv	34 hours	9	-1/+238
\|
*	add traffic counter	tv	34 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.
*	nodes prefer stable neighbours	tv	34 hours	1	-10/+89
\|
*	assess swarm stability	tv	34 hours	8	-11/+330
\|
*	record RTT sampling instant	tv	35 hours	4	-30/+104
\|
*	prefer closer sources to catch up	tv	35 hours	3	-3/+49
\|
*	record RTT from keepalive messages	tv	35 hours	7	-20/+148
\|
*	pull missing changes	tv	35 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.
*	find reachable neighbours	tv	36 hours	3	-55/+162
\|
*	sync with neighbours	tv	36 hours	6	-4/+171
\|
*	add neighbour graph	tv	36 hours	2	-0/+180
\|
*	add member registry	tv	36 hours	4	-1/+73
\|
*	use nonce in handshake	tv	37 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	37 hours	1	-2/+48
\|
*	consolidate backoff code	tv	37 hours	4	-49/+99
\|
*	retry using fresh messages	tv	37 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	37 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	40 hours	1	-0/+3
\|
*	drop stall breaker; resend needed changes	tv	40 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.
