Notes

Nimbus v23.3.1 is a medium-urgency point release addressing a number of accidental configuration handling breaking changes that were shipped in the v23.3.0 release. It also improves the stability of Nimbus when paired with a Besu execution client and improves the fault-tolerance when driving multiple execution clients.

Fixes

• Nimbus was performing eth_getLogs request with parameters that were exceeding the default --rpc-max-logs-range=1000 limit on Besu. This was a non-fatal issue that resulted in slower deposit syncing speed and the frequent warning message "Connection to EL node degraded". The limit will be increased in the next mainnet release of Besu, but Nimbus v23.3.1 honours the existing limit at the cost of a slightly slower syncing speed with all other execution clients:

• v23.3.0 did not support Engine API URLs which don't specify a protocol in the URL (e.g. http, https, ws or wss). v23.3.1 is backwards-compatible with all previous Nimbus releases:

• v23.3.0 produced a parsing error on TOML configuration files that specify the web3-url parameter as an array of strings. v23.3.1 is backwards-compatible with all previous Nimbus releases and introduces a new more convenient way for specifying the Engine API configuration in TOML:

• v23.3.0 removed the hidden configuration option --web3-force-polling which remained in use by some users. v23.3.1 restores the option as a deprecated one. Please note that all hidden configuration options are intended for use only by the Nimbus development team for testing purposes:

• The release addresses a potential crash triggered by Engine API connections experiencing frequent error responses:

• The release addresses a potential issue where a single non-synced execution client may cause the Nimbus sync state to revert to synced/opt, even when all validator duties can be performed through the remaining execution clients that are still synced:

Nimbus v23.3.0 was low-urgency upgrade bringing full support for the upcoming Capella hard-fork on the Goerli testnet. Keep an eye out for future mainnet releases!

Improvements

• You can increase the resilience of your setup and eliminate any downtime during upgrade procedures of the execution client by allowing your beacon node to manage multiple execution clients. To enable this mode, just specify multiple URLs through the --el option (alias of --web3-url) when starting your beacon node:

  ./run-mainnet-beacon-node.sh \
    --el=http://127.0.0.1:8551 \
    --el=ws://other:8551 \
    --jwt-secret=/tmp/jwtsecret

  As long as any of execution clients remains operational and fully synced, Nimbus will keep performing all validator duties. To carry out an upgrade procedure without any downtime, just restart the execution clients one by one, waiting for each instance to re-sync before moving to the next one.

  If you use this mode with different execution client implementations, Nimbus will act as an execution layer consensus violation detector, preventing the publishing of blocks that may trigger a catastrophic partitioning in the network.

• The metrics engine_api_responses, engine_api_request_duration_seconds and engine_api_timeouts provide statistics about latency and response status codes for all requests sent to each individual execution layer URL:

  #4465
  #4707

• Nimbus will now attempt to connect to a locally running execution client even when the options --el and --jwt-secret are not specified. This is made possible by the following proposed standard:

  ethereum/execution-apis#302

  Please note that the standard hasn't been implemented in any execution client yet.

• Nimbus now support the latest version of the Builder API, adding support for the Capella hard-fork:

  #4643

• Improved diagnostic messages and more spec-compliant behavior of the Nimbus validator client when being paired with a non-synced or optimistically synced beacon nodes:

  #4643
  #4657
  #4673

• The Sqlite3 database engine has been upgraded to version 3.40.1:

  #4649

Fixes

• The doppelganger detection now acts safer after a period of lost network connectivity

  #4616

• The doppelganger detection now acts safer in the presence of out-of-order responses from the beacon node:

  #4691

• Nimbus can now export ERA files for the Sepolia network:

  #4689

• The --history=prune mode will no longer interfere with serving light client data for the full retention period as mandated by the spec:

  #4702

• Nimbus now downloads a longer range of recent execution blocks in order to avoid potential situations where our Eth1Data votes fail to agree with the honest majority in the network:

  #4588

• Nimbus has addressed a potential interruption of deposit syncing when connected to Geth over WebSocket:

  #4708

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
