#### Notes for Validators

* **Breaking upgrades**: Require careful coordination and state migrations.
* **Manual upgrades**: These must be installed directly by node operators — cosmovisor or other automated tooling won’t handle them.
* **Upgrade heights**: Ensure your node halts and updates **before** reaching the listed height to prevent consensus issues or downtime.
