What changed?

Most of the improvements in this release were raised by our Community via GitHub Issues and Discord channel suggestions.

We are continuing to improve our Execution layer Client by fixing improvements raised by the community, improving stabilization, reducing the data size and UX of our Client.

Release Overview

• More profitable blocks post-merge
• Fixes & improvements in synchronization and networking
• Fixes & improvements in JSON-RPC: eth_getFilterLogs, parity_PendingTransactions, eth_subscribe, eth_getBlockByNumber, eth_getBlockByHash
• Optimization of disk reads and CPU usage
• First part of Shanghai EIPs

Block Construction

• Continuous block improvements until slot finishes, refreshing added transactions, allows making more profitable blocks (#4488)
• Added ExtraData configuration for post-merge blocks The default ExtraData is Nethermind, but you can set it via Mining.ExtraData config

JsonRPC

• eth_getFilterLogs returns different output for the same parameters
  • Corrected behaviour of eth_getFilterLogs to return the right logs for subsequent calls with the same filter (created by eth_newFilter) (#4771)
• Add optional argument Address in parity_pendingTransactions - Implementation, Tests, Spacing Fixes
  • parity_pendingTransactions call now accepts an argument address to filter the pending transactions originating for address (#4413)
• Fix logIndex in logs subscription - fix log index in logs subscription, adjust tests
  • Fix logIndex field in eth_subscribe - now logIndex return the same index regardless of whether it's coming back from eth_subscribe or eth_getLogs (#4733, #4633)
• The second part of eth_getBlockByNumber and eth_getBlockByHash optimization -
  • The previous release optimized requests only if the second parameter returnFullTransactionObjects was set to false. Now it is optimized for both boolean values.

Sync

• Reduce old receipts response time
  • Old receipts sync time improvement on slow IO
• Fix forward sync may stuck on slow peer
  • Fixed forward sync sometimes stuck on a slow peer
• Disable snap capability after healing instead of StateRanges

Networking

• Multiple peering improvements
  • Fix node speed does not update
  • Fix peer dropping randomly
  • Fix stuck when restarting with a new pivot
  • Fix Syncing to a Chain with Invalid Terminal Block
  • Fix peer manager keep reconnecting too quickly - adding connection delay if client disconnects (#2191, #4747)
• Drop support for old Eth protocols - eth/62, eth/63, eth/64, eth/65
  • Remove pre eth66 network protocols - This is a breaking change (#4717)
• UPnP port forwarding support
  • UPnP support - Add a plugin that allows automatic port forwarding on supporting router. Enabled by --Network.EnableUPnP=true config value.

TxPool

• Optimize deployed code filter for the state to be accessed less
  • Optimization reduces disk reads and CPU usage of the node

EVM

Added two Shanghai upgrade related EIPs:

• EIP-3651 Warm COINBASE
• EIP-3855 PUSH0 instruction added

HealthChecks

• Disable HealthChecks UI if HealthChecks is not enabled
  • If HealthChecksUI and HealthChecks are not both enabled user will see a warning and UI would not be added

Metrics

• Fixed unable to use metrics on pull mode without specifying gateway url
• Added Engine API metrics
• Added a new TxPool metric - PendingTransactionsWithExpensiveFiltering

Log

• Fixed Could not reach PushGatewayUrl error appearing in logs a lot
• Fixed peer header printed to logs without any peers
• Added time unit (microseconds) to JSON RPC report
• Fixed incorrect logs for old receipts and old bodies. The ancient barriers were ignored.

Config

• Revised product version and client id
• Changed the default setting of Merge.Enabled to true
• Added none.cfg to allow CLI configuration without mainnet defaults
  • Add an empty config file to allow configuring everything via command line flags without carrying mainnet defaults
• Added new Chiado chainspec and config

ENR

• Properly validate length (#4748)
