prysmaticlabs/prysm v4.0.2

on GitHub

This release fixes a critical bug on Prysm interacting with mev-boost / relayer. You MUST upgrade to this release if you run Prysm with mev boost and relayer, or you will be missing block proposals during the first days after the Shapella fork while the block has bls-to-exec changes.
Post-mortem that describes this incident will be provided by the end of the week.

One of this release's main optimizations is revamping the next slot cache. It has been upgraded to be more performant across edge case re-org scenarios. This can help with the bad head attestation vote.

Minor fixes in this release address a bug that affected certain large operators querying RPC endpoints. This bug caused unexpected behavior and may have impacted the performance of affected operators. To resolve this issue, we have included a patch that ensures proper functionality when querying RPC endpoints.
