c2pool v0.2.12.2
c2pool v0.2.12.2
LTC hotfix on top of v0.2.12.1. New LTC nodes should use this release. The share version 3601 flag day is unchanged: 2026-11-13 00:00:00 UTC. Nodes already running v0.2.12.1 on the V36 share chain do not have to upgrade. DASH, BTC, DGB, BCH and BIP-110 nodes are unchanged from v0.2.11.1.
LTC: bootstrap only from the V36 share chain
The built-in bootstrap list held hosts of other share chains: an old V35 p2pool and a separate chain. A fresh c2pool-ltc node that reached them first could follow their chain instead of the V36 one. Its dashboard then showed V35 shares and "VOTING".
- The built-in list now holds V36 share-chain nodes only.
- Earlier versions saved the bootstrap list in
<data-dir>/ltc/pool.yaml. The foreign-chain hosts are now dropped from it when it is loaded. - If your node shows V35 shares or "VOTING", stop it, delete
<data-dir>/litecoin/sharechain_leveldband<data-dir>/ltc/addrs.json, and start this release. Give one or two V36 nodes with-n HOST:9326(for exampleltc.voidbind.com:9326).
LTC: P2P port that cannot be bound
When the P2P port was taken, the node kept running but dropped every peer at the handshake. It now runs without advertising a listen port.
Upgrading from v0.2.12.1
Everything else in v0.2.12.1 applies: the share version 3601 flag day, merged mining with several aux chains, and the payout changes. See the v0.2.12.1 notes.
