Notes
Nimbus v22.5.2 is a medium-urgency maintenance release updating Ropsten testnet support as well as updating the fork choice rule to use the latest proposer boost score.
If you are running validators, this upgrade will prevent you from voting for blocks that later get orphaned -- as happened with the deep reorg.
Fixes:
-
Modify proposer boost from 70% to 40% to improve network consensus
14dc385 -
Increase Ropsten TTD to prevent it from being readily triggered by mining
#3668
Improvements (v22.5.1):
-
More spec-compliant handling of JSON fields in REST (for better compatibility with added and optional fields)
#3647 -
Support for the Ropsten testnet (intended for merge testing)
#3648
Nimbus v22.5.2 builds on Nimbus v22.5.0 and v22.5.1 -- low-urgency maintenance releases implementing the proposer boosting fork-choice policy and compliant with the latest Bellatrix specifications. v22.5.2 also provides an early preview of our built-in support for BLS threshold signatures (via regular Web3Signer instances): this marks the first step of our long-term secret-shared validators roadmap which enables node operators and staking pools to deploy Nimbus in secure high availability setups.
Fixes (v22.5.1):
- Restore compatibility with certain Web3 endpoints
#3645
Fixes (v22.5.0):
-
The potential for missed block proposals in the case where an invalid deposit is submitted to the deposit contract
#3607
#3639 -
A crash triggered by the use of Web3Signer remote keystores
#3616 -
A rare crash triggered when Nimbus is performing a large number of concurrent HTTP requests

Improvements (v22.5.0):
-
A safer fork-choice algorithm which implements the proposer boosting policy
ethereum/consensus-specs#2353
#3565 -
A completely revamped snappy implementation which brings significant speed-ups
#3564 -
Support for the latest Bellatrix specifications (a.k.a. The Merge) + all Kiln testnets
#3590 -
An initial release fеaturing a preview of built-in support for distributed keystores, (part of our secret-shared validators roadmap)
#3616 -
Reduced CPU usage when serving blocks to other syncing clients
#3598 -
A more spec-compliant implementation of the
/eth/v1/config/specREST end-point (implementing the v1.1.10 version of the spec)
#3614 -
Improved compatibility with all versions of Web3Signer
#3640
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
