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:

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)

@fjl fjl released this 03 Mar 12:47
v1.17.1
16783c1

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:
  • 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)

@fjl fjl released this 17 Feb 16:15
v1.17.0
0cf3d3b

This is a feature release, with all accumulated development from the last 3 months. See below for the highlights.

Note that this release contains multiple critical security fixes, as well as many bug fixes, and is recommended for all users. However, if you are cautious about upgrades, you can also install v1.16.9 which has just the critical security fixes. Specifically, this release fixes CVE-2026-26313, CVE-2026-26314, CVE-2026-26315.

We recommend recreating your p2p node key after installing this update, which you can do by removing the DATADIR/geth/nodekey file before restarting geth. Note this will cause a change in the p2p node ID, which may break static peering setups.

Highlights

Path-based Archive Node with Proofs

The path-based archive node can now serve proofs (via eth_getProof) for the state of older blocks.

You can configure the block range that supports proving independently from other archive state availability. Specifically, you can use the --history.trienode command-line flag to set the amount of blocks for which tree nodes will be tracked.

This feature is disabled by default. Note that state history cannot easily be recovered once deleted, as it can only be generated by processing blocks. However, you can enable trienode history (and/or state history) at any time to turn a full node into a partial archive node, keeping state from that point in time onwards.

#32727, #32621, #33551, #32981, #33399, #32913, #33303, #33584, #33329, #33681, #33103, #33098, #33515, #32247

EraE History Support

Geth now suports the EraE file format, an archival format for post-merge chain history.

#32157, #33827

OpenTelemetry Tracing

OpenTelemetry tracing is now supported by the RPC server, including support for distributed tracing.
We have also added some tracing spans for block processing via the engine API, i.e. engine_newPayload.

#33599, #33452, #33780, #33521

All Changes

Geth CLI

  • The geth version-check subcommand has been removed. This command checked the geth website for signed vulnerability notices, and would tell if updates are necessary (#33498)
  • There is now a --miner.maxblobs command-line flag to set a limit on blobs included in built blocks (#33129, #33302)
  • Geth now supports continuous profiling with Grafana Pyroscope (#33623)
  • A rare bug that could halt block production in geth --dev mode was fixed (#33146)
  • A new --rpc.rangelimit flag configures the maximum block range for eth_getLogs (#33163)
  • geth --exitwhensynced will now set the finalized and safe block (#33038)
  • geth --ethstats now reports the newPayload processing time to the stats server (#33395)

  • The evm blocktest command can now read filenames from stdin when no path is provided (#32824)

Fork Implementation

Core

  • The crypto/ecies library allowed extraction of the private key used for key derivation via observation of response timing. We recommend rotating the node key after applying this update. (#33669)
  • When a missing block is encountered during tx unindexing, Geth will now skip it and move on instead of entering an infinite loop. (#33573)
  • Geth now optionally collect and export metrics about the total state size (#33254, #33376, #33415)
  • There is a new OnStateUpdate hook, which is called after all state of a block has been committed. This gives access to the changeset of the block. (#33490)
  • Some minor tracing bugs have been fixed (#32919, #33148, #33644, #33214)
  • Various minor issues in the freezer database have also been fixed (#33747, #33025, #33203, #33344)
  • The setHead operation now unsets the finalized block, in cases where the rolled-back block range extends before it. (#33486)
  • The SignatureValues method of types.Signer now reports an error for invalid signature sizes (#33647)
  • Geth prints detailed log messages for 'slow blocks' (#33655, #33525, #33442, #32812, #33659, #33532)
  • Pebble configuration has been tweaked for improved performance (#33697, #33353, #33315)
  • A rare crash in the log indexer related to reorg handling has been fixed (#33810)
  • Internal state diff size accounting has been corrected, so state diffs will now be flushed to the disk store less often (#33505)
  • Since the keccak256 hash function variant used by Ethereum no longer has a fast-path in the standard library, we have vendored the keccak implementation back into our repository (#33323)

Library

  • The RLP library now has a RawList type for dealing with un-decoded lists in a more convenient way (#33755, #33834, #33840, #33841)
  • The low-level RLP iterator and uses of it have been improved (#33245, #33188, #33820)
  • Clef can now sign blob transactions with cell proofs (#32910)
  • Fixed some corner-case bugs in metrics exporting (#33749, #33748)
  • The hardware wallet library now supports the Ledger Nano Gen5 and correctly enables EIP-712 signing for all supported versions. (#33297, #33113)
  • SignTextWithPassphrase now works correctly with all supported hardware wallets (#33138)
  • Some minor bugs were fixed in the keystore implementation (#33606, #33602, #33090)
  • The bitutil.XORBytes function has been deprecated in favor of stdlib package crypto/subtle (#33331)
  • A memory leak in the beacon chain light client was fixed (#33483)

RPC

  • eth_getTransactionByHash now returns the blockTimestamp as part of the transaction object (#33709)
  • Error codes for some conditions in eth_simulateV1, eth_getLogs, eth_getStorageAt have been improved to better comply with the execution RPC spec (#33007, #33320, #33282)
  • eth_simulateV1 now selects the correct set of precompiles for the simulated header (#33363)
  • eth_sendTransaction and eth_fillTransaction now default to EIP-1559 (#33058)
  • The GraphQL implementation has received some bug fixes for cases where a resolved item is not found. (#33184, #33225)
  • In GraphQL, the gasPrice is now retrievable for transaction types 0x3 and 0x4 (#33542)
  • The RPC server now enables plain-text HTTP2 for improved performance (#33812)
  • The RPC client no longer sends spurious RST_STREAM HTTP2 frames (#33122)
  • Some minor JSON encoding bugs have been fixed in ethclient (#33693, #33242, #33464)
  • The gethclient has a new wrapper of the callTracer (#31510)
  • In the callTracer, reported logs now contain an index field which is the index of the log within the transaction (#33629)

P2P Networking

  • The transaction pool heartbeat mechanism had some fixes for potential resource leaks (#33704)
  • The eth and snap protocol implementations nows validates most p2p messages before decoding their content. This improves security and sync performance in some cases. (#33835)
  • The blob transaction pool has seen some bug fixes and now accepts nonce-gapped transactions to a very limited extent (#32717, #33775, #33474, #33352, #33301, #33260)
  • Snap sync status is now tracked better, ensuring a snap sync will not be triggered accidentally by the engine API (#33157)
  • The snap sync scheduler was improved to better protect the trie database against accidential mutations while the node is processing blocks. This resolves some edge cases where the database could be corrupted (#33428)
  • The header sync implementation was fixed to better deal with setHead operations during sync (#33481)
  • Peer connections delivering stale transactions will be penalized less, since delivery of a few stale transactions is a common occurrence. (#32725)
  • Peers announcing transactions of one type, and delivering a different type, are now disconnected as penalty (#33378)
  • Similarly, peers delivering invalid KZG proofs will now be disconnected (5b99d2b)
  • The transaction pool has new metrics for the number of accounts with transactions (#33646, #33654)

⚠️ Do not use v1.16.6 for the Fusaka upgrade! Please use v1.16.7, which contains an important security fix. ⚠️

This release enables the Fusaka hardfork on Ethereum mainnet
The fork is scheduled to occur at 2025-12-03 21:49:11 UTC.
This release also enables the BPO1 and BPO2 forks for mainnet at 2025-12-09 and 2026-01-07 respectively.

Fusaka

  • Set mainnet timestamps for Osaka (#33063)
  • Enable Fusaka for geth --dev mode (#32917)

RPC

  • Add eth_sendRawTransactionSync which waits until either a timeout or the transaction is mined. This feature is mostly useful on L2s with lower blocktimes. (#32830, #32930, #32929)
  • Add support for eth_simulateV1 in ethclient (#32856)
  • Fix for an issue that might crash debug_traceCall (#33015)
  • Fix for an issuer where local transactions were not persisted to the journal (#32921)

v1.16.5

This is a maintenance release. We are issuing this release mostly to add a conversion path for blob proofs submitted via eth_sendRawTransaction. See https://blog.ethereum.org/2025/10/15/fusaka-blob-update for more information.

RPC

  • eth_sendRawTransaction has an upgrade path for blob proofs after the Fusaka fork. Note this is temporary. We will remove support for blob proof conversion during the v1.17.x release cycle, please update RPC client libraries to support cell-level (v1) proofs. (#32849)
  • eth_subscribe now supports a transactionReceipts subscription. There is also a wrapper in ethclient for this new subscription type. (#32697, #32869)
  • eth_simulateV1 was fixed to return the block timestamp in logs, like eth_getLogs does. (#32831)
  • In the abigen v2 runtime, BoundContract.Transfer will now verify that the contract has a payable fallback or receive method. (#32374)
  • A keccak256preimage tracer has been added. (#32569)

Networking

  • The eth protocol handler will now drop peers sending duplicated transactions. This is to unify behavior with other client implementations. (#32728)
  • A regression in the discovery system could cause high CPU usage under synthetic conditions (i.e. in tests). (#32912)
  • A very rare shutdown hang related to peer discovery is resolved. (#32572)
  • The eth protocol test suite has a new post-merge test chain and saw some bug fixes for flakey tests. (#32834, #32850)

Core

  • Our freezer implementation now supports partial reads, i.e. reading just a slice out of a larger stored value. This functionality is used for the archive node state history. (#32132)
  • The trie database now implements a storage layer for 'trie history', a precursor to serving historical state proofs for the path-based archive node. (#32596)
  • The txpool/valid.meter metric has been corrected. (#32845)
  • The engine API saw some fixes related to fork compatibility checks. (#32800, #32731)
