go-ethereum v1.17.4

This is a maintenance release with accumulated bug fixes and improvements, and is recommended for all users. It also continues the implementation work for the upcoming Amsterdam hardfork.

One thing worth highlighting:

Clef has been removed. The standalone clef signer has moved to https://github.com/ethereum/clef (#35097).

Fork Implementation (Amsterdam)

EIP-7928: Block-Level Access Lists: the block access list is now constructed and verified during block execution, with the serving side of the eth/71 BAL messages implemented (#34652, #34803, #34879, #34957, #34967, #34972, #34977, #35110)
EIP-8189: snap/2, a new state-sync protocol based on block-level access lists, has been added (#34626, #34807, #35098, #35155, #35158, #35163, #35178, #35180, #35181)
EIP-8037: state-creation gas cost increase, has been implemented (#33601)
- The tracing system provides a new OnGasChangeV2 hook for multi-dimensional gas (#34946)
engine_newPayloadWithWitnessV5 has been added and the witness format now uses the canonical spec field ordering (#35009)
The evm t8n tooling has been updated for Amsterdam, adding BAL and slot-number support and binary-trie leaf export (#34843, #35025)
For EIP-7843, the slot number is now set for the pending block post-Amsterdam (#34792, #35036)

Geth

Caches are now sized against the cgroup memory cap (e.g. Docker --memory) when one is set (#34947)
A number of small command-line flag and logging issues have been fixed (#33880, #34732, #34943, #34948, #35011, #35104, #35116, #35136)
A number of long-deprecated command-line flags have been removed (#35021)

RPC

eth_baseFee has been added, returning the base fee of the next block (#34904, #35023)
eth_capabilities has been added, letting clients discover which historical data a node can serve (#33886)
debug_clearTxpool has been added to clear the transaction pool (#33347, #35130)
State-reading methods (eth_getBalance, eth_getCode, eth_getStorageAt, etc.) now default the block parameter to latest when omitted (#35100)
Fixes for eth_simulateV1: an incorrect “base fee too low” error code and a pre-Shanghai withdrawal regression (#34951, #34939)
debug_setHead now propagates rewind errors instead of silently ignoring them (#35001)
EIP-7702 transactions with a nil To address are now rejected (#35094)
HTTP RPC responses now always set Content-Length, and a WebSocket handshake status-code bug was fixed (#35072, #35111)
The client can now configure trace-context propagation via the traceparent header, and response writes are now traced (#35132, #35049)

GraphQL

GraphQL request bodies are now limited to 5 MiB (#35034)
Log-range queries with begin > 0 and end == 0 are now rejected (#35032)
The Block.raw resolver now returns empty bytes when the block body is missing (#35027)

Core

A global cache for JUMPDEST bitmaps speeds up EVM execution (#34850)
EVM stack operations are now computed in place, avoiding per-operand copies (#35156)
New code-cache hit/miss meters have been added (#34821)
A shutdown race in snapshot generation has been fixed (#33540)

Engine API & Blobs

Engine API JSON encoding for large blob payloads has been optimized, and gzip is disabled on the engine API (#33969, #35057)
engine_hasBlobs has been added, and engine_getBlobs now counts only actually-available blobs (#34859, #35028)
A cache for GetBlobs requests reduces engine API latency, and otel tracing has been added to the GetBlobs endpoints (#35124, #35026)
Reorged v0 blob sidecar transactions are now dropped rather than converted (#35099)
testing_commitBlockV1 has been added as the write companion to testing_buildBlockV1 (#34995)
New payloads are now imported at genesis regardless of sync status (#32673)

Networking

NAT STUN discovery no longer fails on IPv6 servers (#35084)
Several snap-sync robustness fixes: uncovered state is removed before resuming, a catch-up stall was fixed, sync restarts when the required BAL is unavailable, and the pivot is frozen once state download completes (#35159)
