Ethereum (Go) - v1.10.22

Geth v1.10.22 enables the Merge for the Ethereum mainnet at a Terminal Total Difficulty of 58_750_000_000_000_000_000_000.

This TTD is expected to be reached on the 15. September 2022.

Merge EIPs

• EIP-3676: Upgrade consensus to Proof-of-Stake
• EIP-4339: Supplant DIFFICULTY opcode with PREVRANDAO

Additional notes about the merge changes

• This release configures the Terminal Total Difficulty for mainnet. (#25528)
• Many engine API issues found by hive have been fixed for this release. (#25552, #25423, #25414, #25416, #25428)
• The Goerli testnet is now internally configured as 'successfully merged'. (#25519, #24538)

JSON-RPC API

• The log filtering system now uses a LRU cache for block logs, speeding up repeated queries for the same block range. The cache size can be configured using the --cache.blocklogs command-line flag. (#25459)
• eth_createAccessList is now much faster when no gas limit is provided. (#25467)
• eth_feeHistory now also works with the finalized block specifier. (#25442)
• The built-in callTracer now supports an option onlyTopCall. Enabling this option makes the tracer skip internal calls. We added this option to enable use of the callTracer to get the return data of reverted transactions. (#25430)

Go-library changes

• Storage of trie node hash preimages is now disabled by default. You can enable it again using the --cache.preimages flag. (#25287, #25538, #25533)
• The ethash mining implemenation now removes temporary DAG files, which could be left of disk when geth was interrupted while generating a DAG. (#25381)
• ethclient now supports the eth_feeHistory method. (#25403)
• The eth wire protocol test suite now supports protocol version eth/67. (#25306)
• RLP-decoding of trie nodes is ~33% faster due to reduced allocations in the decoder. (#25357)
• The RPC server supports a new option ReadHeaderTimeout. (#25338)
• Registering of clef ruleset UIs should now work correctly. (#25455)

Build

• Geth binaries in docker are now statically-linked. (#25492)
• This release is built using Go 1.18.5. (#25461)
