Notes
Nimbus v1.5.5 is a medium-urgency bugfix release which contains a number of significant optimisations; of particular note is a 6x speed-up in epoch processing and 2x speed up in Altair block processing.
In addition, v1.5.5 adds support for the web3signer protocol (currently in BETA). This allows staking pools and other providers with an advanced key handling strategy to use Nimbus.
We've fixed:
- The potential for missed block proposals when a third-party validator client (with at least one imported validator) was used with a Nimbus beacon node (with no imported validators): this happened because the
--web3-urlparameter was mistakenly ignored when running without an in-beacon-node validator - A rare condition in which the REST service became unavailable
- Inappropriate error messages produced by the REST API: when a validator client published the same attestations or sync committee messages through multiple beacon nodes.
Improvements:
- 6x speed-up in epoch processing: #3089
- 2x speed up in Altair block processing: #3115
- A 12% (minimum) reduction in the outgoing GossipSub traffic: #3112
- Across the board performance improvements in the REST API: #3092
- The REST API can now report sync committee information for the next sync period: #3133
- Added support for the web3signer protocol (beta release): #3077
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
