Polygon Labs Urges Node Operators to Upgrade Following Dual Hard Forks
Polygon Labs issued an urgent binary update notice for node runners following the Austin and Kyoto hard forks.

Polygon Labs has released an urgent upgrade advisory for network validators and node operators following the completion of the Austin and Kyoto hard forks. The network upgrades addressed critical consensus vulnerabilities, including potential block-stalling triggers and peer-to-peer crash risks.
Operators running outdated client versions have fallen out of sync with the canonical chain, making immediate binary updates necessary to maintain network integrity and validator participation. The fixes streamline validator operations and bolster network resilience against consensus disruptions.
Ensuring all node participants migrate to updated binaries is vital for maintaining throughput, finality, and security across Polygon's proof-of-stake infrastructure.
Key takeaways
- Polygon Labs published an urgent upgrade notice following two network hard forks.
- The patches resolve consensus bugs, peer crashes, and validator workload issues.
- Node operators must upgrade immediately to remain aligned with the canonical chain.
