v0.19.2 - 2024-03-07

This release downgrades a dependency to ensure performance at high validator counts, and sets a more recent timestamp for builder API registrations to make validator migration more seamless.

A reminder on Produce Block endpoint V3

The Charon team is working towards supporting the Produce Block V3 endpoint, but in the meantime v0.19.2 will still only support the V2 endpoints.

At the time of releasing not all validator clients default to the new Produce Block V3 endpoint, for those that do, set the following flags on your validator client to ensure your validator asks for v2 blocks until a version of charon supports the v3 endpoint:

Lodestar: --useProduceBlockV3=false as CLI parameter at startup
Lighthouse: --produce-block-v3=false as CLI parameter at startup
Teku: --Xblock-v3-enabled=false as CLI parameter at startup
Nimbus automatically falls back to V2 endpoints
