🚨 Mandatory Mainnet (pacific-1) Upgrade — v6.6

⚠️ This is a MANDATORY upgrade for all pacific-1 mainnet node operators and validators. Nodes that do not upgrade will halt at the upgrade height and fall out of consensus.

📋 Upgrade Summary

Note: The on-chain Upgrade Name (v6.6) is intentionally different from the git tag (v6.6.0). Cosmovisor matches on the Upgrade Name, so the directory must be named v6.6.

✅ What Operators Need to Do

1. Build / download the new binary from this release (v6.6.0).
2. Wait for the chain to halt automatically at height 224201091. Do not stop your node manually before this height.
3. Swap in the new binary and restart your node once the halt occurs.
4. Confirm your node resumes producing/syncing blocks past the upgrade height.

💡 Cosmovisor users: place the new binary under upgrades/v6.6/bin/ (using the upgrade name, not the git tag) ahead of time, and the switch will happen automatically at the upgrade height.
