*	warn about unresolvable seeds once; log success	tv	24 hours	1	-7/+22
\|
*	genesis conflicts seeds or recover-from	tv	24 hours	1	-16/+19
\| \| \| \| \|	genesis together with seeds or recover-from is now an error wherever the values come from, and not settled by precedence.
*	add disk I/O stats	tv	25 hours	6	-27/+138
\|
*	add possibility to start with a document	tv	25 hours	4	-13/+163
\| \| \| \|	The --recover-from option allows a node start with a given document.
*	add state file	tv	26 hours	7	-4/+266
\| \| \| \| \|	This allows storing the swarm ID and additionally discovered seeds, which prevents a formerly genesis node to start a new document.
*	put swarm ID into the document	tv	26 hours	4	-6/+27
\|
*	add genesis flag and never give up	tv	27 hours	3	-76/+112
\| \| \| \| \| \| \| \| \|	The --genesis flag has been introduced to start with a new document. This prevents restarts to accidentally start with a new document and accept reads/writes, causing a second swarm to appear. Additionally, bootstrapping doesn't timeout anymore as that's of no use for nobody.
*	compact remake fixes base at the commit	tv	40 hours	5	-40/+138
\| \| \| \| \| \| \|	Instead of fixing base heads at when proposed, compact fixes them when committing. This shrinks the window where writes can be lost if their author restarts to the switch delay; during replace and import remakes writes can still be lost during the voting period.
*	fix wording around swarm key admission	tv	40 hours	2	-3/+3
\|
*	allow superseding expired remakes	tv	41 hours	4	-26/+279
\|
*	remake coordinators resume after restart	tv	41 hours	3	-5/+49
\|
*	don't commit expired remakes	tv	41 hours	1	-58/+93

*	add votes register	tv	41 hours	8	-124/+507
\|
*	bound stable-hub degree	tv	42 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	42 hours	3	-2/+60
\|
*	cache heads	tv	42 hours	7	-24/+61
\| \| \| \|	To reduce the number of write locks, heads are now cached.
*	corroberate newer epochs	tv	42 hours	1	-11/+53
\|
*	follow and download from ready members only	tv	43 hours	3	-3/+29
\|
*	being caught up needs some heads	tv	43 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.
*	only protocol-writers may modify _continuum	tv	43 hours	6	-14/+63

*	put remake content into blobs	tv	44 hours	15	-79/+319

*	add configuration files	tv	47 hours	4	-107/+1261
\|
*	wire up --mycelium-tcp-listen-port	tv	48 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	2 days	7	-95/+406
\|
*	add electorate	tv	2 days	3	-8/+109
\| \| \| \| \|	For an upcoming change in remake coordination, nodes now maintain their self-assessed liveness in the document.

*	measure document saved-size only after changes	tv	2 days	2	-18/+43

*	add the import kind of remake	tv	2 days	3	-49/+200

*	add endpoint to export the document	tv	2 days	3	-0/+88
\| \| \| \|	GET /admin/document to retrieve the automerge document.

*	expose stats via the API	tv	2 days	2	-0/+136
\| \| \| \|	GET /admin/stats to retrieve all stats.
*	add swarm stats	tv	2 days	9	-1/+238
\|
*	add traffic counter	tv	2 days	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	2 days	1	-10/+89
\|
*	assess swarm stability	tv	2 days	8	-11/+330

\|
*	record RTT from keepalive messages	tv	2 days	7	-20/+148
\|
*	pull missing changes	tv	2 days	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.
