Hello Everyone,
We have released a new version of heimdall-v2: v0.7.1 for Polygon Amoy and Mainnet. This release is the public counterpart of the private v0.7.0 release that delivered the Phuket hardfork, already activated on both networks:
-
Amoy: block
32,276,400(activated April 16, 2026) -
Mainnet: block
44,070,000(activated April 29, 2026)
In addition to the gated changes in v0.7.0, v0.7.1 includes a small post-rollout fix that relaxes a heimdall clause causing vote-extension rejections when heimdall is temporarily unable to query bor. This makes node operation more resilient to brief execution-client lag.
Upgrading to v0.7.1 is recommended for all node operators on all networks.
Steps for upgrading Heimdall
- Stop heimdalld service
sudo service heimdalld stop
- Install heimdall with a version tag, network name, and node type (sentry or validator).
# Replace the network and node type
curl -L https://raw.githubusercontent.com/0xpolygon/install/heimdall-v2/heimdall-v2.sh | bash -s -- v0.7.1 <network> <node_type>
- Check heimdall version (it should print
0.7.1)
/usr/bin/heimdalld version
- Restart heimdall service
sudo service heimdalld start
- Restart the telemetry services
sudo service telemetry restart
