This is a quick release that postpones the Amsterdam fork on the Hoodi testnet, previously scheduled for Oct 26, 2026, 17:42:48 UTC. Hoodi node operators running v1.17.9 must upgrade before then. A new date will be set in a future release; other networks are unaffected.

Snap sync now switches to snap/2 automatically once Amsterdam is active. Use --snap.v2=false or --snap.v2=true to force a protocol.

Changes

• Cancel the Amsterdam activation on Hoodi (#36001)
• Use snap/2 automatically once Amsterdam is active (#35989)
• Optimize DUP/SWAP dispatch in the interpreter (#35959)

For a full rundown of the changes please consult the Geth 1.17.10 release milestone.

As with all our previous releases, you can find the:

• Pre-built binaries for all platforms on our downloads page
• Docker images published under ethereum/client-go (use "stable" tag)
• Ubuntu packages in our Launchpad PPA repository
• macOS packages in our Homebrew Tap repository

It also contains changes to the EVM to improve the performance significantly.

This release is recommended for all users running their nodes on the Hoodi testnet.

This release is recommended for all users.

All Changes

Security

• In the eth and snap p2p protocol handler, DoS resistance has been improved for multiple packet handlers (#35862, #35883, #35859, #35857, #35904, #35856)
• JUMPDEST analysis caching has been hardened for attack cases after Amsterdam fork (#35881)

• A post-Amsterdam DoS vector related to BAL accounts is resolved (#35865)
• A rogue STUN server could crash the node with an invalid response (#35863)

RPC

• eth_simulateV1 has been fixed to correctly report ETH transfer logs post-Amsterdam (#35617)
• eth_simulateV1 virtual blocks are now aligned with the Amsterdam spec (#35668)
• eth_capabilities reports the availability of receipts bounded by the transaction hash index (#35878)
• For eth_call and related operations, the transaction gas limit is no longer applied (after Amsterdam fork) (#35845)
• A post-Amsterdam crash in journaled live tracers core/tracing: handle creator nonce change without an open frame (#35896)
• An edge case in processing beacon chain head updates after unclean shutdown is resolved (#35804)
• abigen will now use sequential nonces when deploying library dependencies of a contract (#35888)

Core Library

• The hard-coded Hoodi testnet beacon chain genesis time was incorrect (#35876)

P2P

• A correctness issue in the EIP-8070 Sparse Blobpool (Amsterdam fork) implementation is fixed (#35860)

Build

• The PPA now publishes for Ubuntu 26.04 "Resolute Raccoon" (#35854)

For a full rundown of the changes please consult the Geth 1.17.8 release milestone.

As with all our previous releases, you can find the:

• Pre-built binaries for all platforms on our downloads page.
• Docker images published under ethereum/client-go (use "stable" tag).
• Ubuntu packages in our Launchpad PPA repository.
• macOS packages in our Homebrew Tap repository.

This is a quick release, cut mainly because publishing v1.17.6 to the Ubuntu PPA failed. It also carries a few fixes merged since then. Both v1.17.6 and v1.17.7 are ready for the Amsterdam fork on Sepolia (Oct 6, 2026), so Sepolia validators can run either version.

Users can now also choose their own history pruning point with --history.chain <block number>:<block hash>. It works both for pruning an existing node with geth prune-history and for snap sync, which then skips downloading the chain history before that block.

Changes

• Add postosaka and custom <block number>:<block hash> history pruning points (#35792)
• Account for both the execution and state gas (EIP-8037) when selecting transactions in the miner (#35773)
• Fix a memory leak by waiting for the block prefetcher when stopping the chain (#35821)
• Release the pathdb clean caches when the database is disabled (#35789)
• Encode and hash the block-level access list once, in a dedicated pipeline (#35772)
• Keep the snap sync v2 pivot moving by applying block-level access lists after the state sync (#35749)
• Only fetch block-level access lists close to the chain head (#35780)
• Skip peers whose announced block range doesn't cover the request (#35723)
• Restore the txpool empty-state fallback during snap sync, fixing the regression introduced in v1.17.3 (#35582)
• Allow restarting an interrupted snap sync when a history cutoff is configured (#35837, #35844)
• Update execution-spec-tests fixtures to v21 (#35835)
• Add five new multi-cloud bootnodes operated by NodeOps alongside the existing bootnodes (#35682)

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

A few things worth highlighting:

• The default GOGC has changed from 20 to 50, trading a higher memory peak for less GC overhead. Set --gogc=20 to keep the old behavior.
• Pebble v2 is now supported as a key-value store backend. Pebble v2 is used when Geth is bootstrapped from scratch, and falls back to Pebble v1 for a pre-existing database. Run geth db pebble-upgrade to explicitly upgrade a legacy Pebble v1 database to v2.

Breaking change for tracing APIs (debug_trace*), specifically the structLog (opcode) tracer. The following response fields now follow the newly established client-wide spec (ethereum/execution-apis#762) and reexec has been removed from the tracing config:

This is a maintenance release with several important bug fixes. Notably, a critical issue in debug_executionWitness could previously corrupt node data, users relying on this RPC endpoint are strongly advised to upgrade.

Geth now also supports syncing with chains where pre-Prague history has been pruned, and allows explicitly removing it via geth prune-history --history.chain postprague.

This is a bug fix release and is recommended for all users. It resolves a regression in snap sync, as well as several security issues.

Geth

• The engine API no longer enables plain-text HTTP2, due to some reports of incompatibilities with the teku CL (#33922)
• The new --metrics.influxdb.interval flag allows changing the metrics reporting interval. (#33767)
• Geth has a new inspect-trie subcommand that prints information about node counts at all state trie depths (#28892)

Core

• Some Amsterdam fork-related changes:
  • EIP-7834 SLOTNUM opcode (#33589)
  • EIP-8024 is now enabled in Amsterdam mode (#33928)
  • Several fixes for EIP-7928 Block-Level Access Lists (#33741, #33743, #33742, #33774)
• Payload building had a fix that could prevent the CL from receiving the latest built payloads (#33908)

Networking

• Geth no longer supports p2p protocol version eth/68 (#33511)
• A rare crash in p2p request tracking is resolved (#33940)
• The transaction pool, and specifically the blobpool, saw some fixes that reduce relaying transactions that likely won't make it into the chain, or have already been included on chain recently. This should reduce txpool traffic (#33607, #33887, #33923, #33893)
• In v1.17.0, a regression in snap-sync was introduced that would cause sync to fail when using --history.chain=postmerge (#33865)
• Snap-sync had a bug where peer connections would stop being used after a timeout or similar event. This wasn't too noticeable for mainnet sync because of peer churn (#33790)
• Unexpected state delivered by peers is now reported during snap-sync (#33898)
• P2P listener metrics now record handshake timeouts correctly (#33539)

RPC

• eth_estimateGas now honors the user-supplied access list (#33849)
• New RPC method: eth_getStorageValues (#32591)
• New RPC method: testing_buildBlockV1 (#33656)

Build

• This release is built with Go 1.25.7 (#33874)
• Our official Docker images are experimentally built with Go 1.26 (#33899)
