v22.9.0

Notes

Nimbus v22.9.0 is a high-urgency upgrade that fixes a critical pre-TTD block production issue affecting users that restarted their node after Bellatrix. It also improves compatibility with Besu, Prysm and slow block builders and provides a speed boost in block processing important for those running on Raspberry Pi and similar hardware.

With the merge drawing near, the focus of this release has been to include low risk changes that improve stability and compatibility - if you are unsure whether to upgrade, do reach out to us in discord to discuss your particular deployment.

A shout out to our great community for reporting and helping diagnose the issues that led up to this release - in particular Michael Sproul (Lighthouse) and Joe Clapis (Rocket Pool).

Improvements

• Allow more time for block builder to deliver block
  #4088

• Improve Bellatrix block processing performance
  #4085 and #4082

• Optimize execution layer calls when not producing blocks, improving Besu performance and compatiblity
  #4055

• Revise timing of execution layer configuration call, resolving warnings that no consensus client is present on Geth and Besu
  #4077

• Log Exchanged engine configuration when first connected to correctly configured execution engine
  #4096

• Switch to nim-websock for websocket connections, resolving delays when payloads exceed 1mb
  #4061

Fixes

• Fix pre-TTD block proposals on nodes that (re-)started after Bellatrix
  #4094

• Fix gossip message id, improving connectivity health with Prysm
  #4076

• Improve handling of blocks deemed invalid by the execution layer
  #4081

• Fix a rare crash that could happen when execution layer disconnected
  #4095

Urgency guidelines

low-urgency: update at your own convenience, sometime within our normal update cycle of two weeks

medium-urgency: may contain an important stability fix, it is better to update sooner rather than later

high-urgency: update as soon as you can, this is a critical update required for Nimbus to function correctly
