Thanks for the update! All Amoy node operators should upgrade to Bor v2.1.0-beta4 before the Bhilai HF at block 22,765,056 (~Jun 11, 10 AM UTC). Remember to update the gaslimit to 45M in your config.toml under [miner] to support PIP-60. Follow the steps: stop service, install with the script, verify version, then restart. This release fixes consensus and localEndBlock issues and adds the Bhilai block. Check the full changelog for details. Staying updated ensures smooth operation and avoids downtime during the hard fork.
