Summary

This release contains a fix for a runtime panic in peer discovery that can cause Lighthouse to shutdown unexpectedly (#2711). It is recommended for all users.

Any user that is running a version prior to v2.0.0 must update before the Altair upgrade on the 27th of October. Nodes running v2.0.0 are fully Altair-ready. However, nodes running any release prior to v2.0.1 will not be patched against the panic fixed in #2711.

Other notable features in this release include:

• Fixes to the standard API (#2712)
• More resilient slashing protection imports (#2598)
• A reduction in validator monitor logging verbosity (#2606)

We recommend updating both the Beacon Node (BN) and Validator Client (VC), however there are no known incompatibilities between v2.0.0 and v2.0.1. Users upgrading from a release prior to v2.0.0 must update both the BN and VC together.

Users upgrading from a release prior to v2.0.0 are advised to read the v2.0.0 Release Notes as they contain important information about breaking changes.

Update Priority

This table provides priorities for which classes of users should update particular components.

User Class	Beacon Node	Validator Client
Staking Users	Medium Priority	Low Priority
Non-Staking Users	Low Priority	---

Users Classes and Priorities

Staking users are those who use lighthouse bn and lighthouse vc to stake on the Beacon Chain. Non-staking users are those who run a lighthouse bn for non-staking purposes (e.g., data analysis or applications).

High priority updates should be completed as soon as possible (e.g., hours or days). Medium priority updates should be completed at the next convenience (e.g., days or a week). Low priority updates should be completed in the next routine update cycle (e.g., two weeks).
