on GitHub

Mandatory, node-only update. Nodes below v1.4.1 are rejected.

What happened

On July 30 nodes started disagreeing on coinbase rewards (COINBASE MISMATCH) and disqualifying each other's blocks. The root cause was a coin-age accounting bug that made long-running nodes slowly drift from freshly started ones, v1.4.1 fixes the root cause.

What's Changed

• IBD: inconclusive sync negotiations no longer get you banned.
• PoM proof store shrinks from ~6 GB to ~1.2 GB.
• Underpaid AI requests are rejected before they ever reach a block.
• Memory fixes (including the cause of OOMs on 16 GB machines).

How to update:

1. Stop your node and replace the binary with v1.4.1.
2. Delete your datadir.
3. Restore the snapshot below (or sync from scratch).
4. Restart.
