🔥 Hotfix 🔥

This hotfix release is identical to v5.1.0, with the exception of some build system fixes for macOS.

If you have already updated to v5.1.0 then you can ignore this release.

The rest of the release notes describe the changes relative to v5.0.0.

Summary

This high-priority release includes a fix to ensure validator's messages are published on the network (#5357). Additionally, out-of-memory crashes are prevented by reducing peak memory usage (#5270).

This release (v5.1.1) and the previous v5 releases (v5.1.0 and v5.0.0) support the Deneb upgrade on March 13, 2024 at 13:55 UTC. Users who are already running v5.0.0 are not required to upgrade to v5.1.0/v5.1.1 before Deneb, but it is recommended.

Notable changes in this release:

  • Lighthouse now caches 3 states by default, rather than 4. The value can be modified with --state-cache-size (#5270)
  • The PATCH /lighthouse/validators/{validator_pubkey} VC HTTP API endpoint has been optimised (#5064)
  • A bug that prevented messages from being published to peers has been fixed (#5357)
  • Performance for NAT'd nodes has been improved (#5345)
  • Concurrent block production has been optimised, providing benefits for SSV operators (#5365)
  • A bug in the validator client which resulted in WARN Not enough time for a discovery search has been fixed (#5305)

Breaking Changes

Breaking Change: Milagro BLS is no longer supported

Lighthouse no longer supports the Milagro BLS library (#5298). This library was not recommended for production use and had to be manually enabled at compile time. We do not expect this change to impact users.

Reminder: Minimum Supported Rust Version 1.75.0

The minimum supported Rust version (MSRV) was updated to 1.75.0 in a previous release (v5.0.0). Users who compile from source (i.e., not Docker or pre-built binary users) will receive the following error if they are using an earlier version of Rust:

lighthouse v5.1.0 (/home/sigp/lighthouse/lighthouse) cannot be built because it requires rustc 1.75 or newer

Users can typically obtain the latest version of Rust by running rustup update.

Update Priority

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

User Class Beacon Node Validator Client
Staking Users High High
Non-Staking Users High ---

See Update Priorities for more information about this table.

Lighthouse BNs and VCs from v5.0.0 and v5.1.0/v5.1.1 are intercompatible. However, we recommend that users update both the VC and BN to v5.1.0/v5.1.1.
