This minor release contains some important protection from excessive resource consumption in some uncommon cases (#2130). We recommend all users update to this version.

The breaking changes in this release should be insignificant for most, see below for more information

New Features

The most notable feature is the new "validator monitor" that allows a BN to provide additional logging and metrics for specific validators.

This provides the long-awaited "validator balance" metric and many, many others.

Additionally, you get additional logs about your validators activities (e.g. attestation inclusion in blocks).

See the validator monitor docs for more information.

Breaking Changes

Breaking changes are fairly minor in this release, but may have edge-case impacts for those running custom or non-Lighthouse validator clients.

• Disallow attestation production earlier than head (#2130)
  • Does not permit the creation of AttestationData via the API for slots earlier than the head. This is a fast patch to an immediate issue, in the future we plan to implement a more flexible solution with #2169.
