v1.17.2

Release notes

This version is a hotfix addressing an edge-case issue with occasional bad block production which was spotted mostly on Ethereum testnets and the Gnosis chain.

Block production

Fixed bad block production. The issue appeared only whenever an empty block was scheduled to be created. [#5411]

v1.17.1

Release notes

This release is mandatory for those who have a node running on Goerli -- previous versions would not work properly in there.
For others, this release can be treated as optional.

Goerli Shapella hardfork to happen at March 14, 2023 10:25:36 PM UTC.

Shanghai

• Updated the chain spec for Goerli (Shapella ready) [#5366]
• engine_getPayloadBodiesBy* methods marked as optional capabilities. This will remove warnings that can be displayed whenever the consensus client is not using those endpoints yet. [#5346]

Proto-Danksharding

• Enabled eth68: Adds the transaction type and size to tx announcement messages in the wire protocol [#5356]

v1.17.0

Release notes

In this release, you can find the first version of withdrawals which is currently used on the Zhejiang network (configs are added in this release, check below for more details.
Also, there are plenty of performance/stability improvements to make our node faster and even more predictable.

Additionally, Sepolia configs including timestamp for Shanghai hardfork are added. This version is mandatory for those who have a node running on Sepolia - previous versions would not work properly in there.
Sepolia Shapella hardfork to happen at: 2/28/2023 4:04:48 AM UTC

Shanghai

• Withdrawals implementation ready and under testing on Zhejiang public testnet [#4731][#5139]
• engine_getPayloadBodiesByHashV1 and engine_getPayloadBodiesByRangeV1 adjusted to the latest spec [#5210]
• Configs for Zhejiang network (Shanghai public testnet. [#5240]
  Here is a tweet from our core dev @MarekM25 about how to use it and start experimenting with the post-Shapella testnet today!
• Unify Engine API failure responses [#5154]
• Fixes for EIP-3860 [#5081] [#5147]
• Introduced null value for latestValidHash when a latest VALID ancestor is unknown + makes semantically equal response with CLs for engine_newPayloadV1 [#5203]
• Implemented engine_exchangeCapabilities method as specified in the spec [#5212]
• Integrate engine_exchangeCapabilities in health-checks (Issue #5185) [#5244]

Proto Danksharding

• Added the possibility to set different chainId and networkId in chain spec [#4850]
• Limit size of TransactionMessage by data size instead of tx count [#4917]
• Added specification, configs, new transaction type and header fields [#4867]
• Added DATAHASH opcode [#4894]
• Added Point evaluation precompile for EIP-4844 [#4890]

JSON-RPC

• trace_block Add zero reward post-merge similarly to pre-merge (Issue #4616) [#5054]
• Reduced RAM consumption for trace_block [#5090]
• Increase JsonRpc.MaxBatchSize to 1024. Together with Prysm team we noticed, that there is a small issue where Prysm can send a little bit more than 1000 requests in single batch so we want to adjust that behavior for them until PR: prysmaticlabs/prysm#11982 will be released. [#5286]

Sync & Networking

• Fix edge case on BeaconHeaders stage causing sync to hang until a better peer is found [#5102]
• Improvements of OldHeaders processing on node restart [#5112][#5119]
• Fixes node disconnection from peers due to error in initial sync, specifically empty receipt received [#5120]
• Added session direction to sync peer report. It simplifies the information if the peer is an incoming or outgoing connection. [#5258]
• Fix establishing a connection on eth/67 [#5113]
• Fix edge case when transitioning from fast sync [#5146]

TxPool

• Fix edge case scenario with Nonce incrementation when eth_sendTransaction is executed multiple times (Issue #4845). [#4926]

Configs

• Updated Chiado bootnodes [#5239]
• Removed Kiln testnet configs [#5181]
• Removed sokol chain and all related items/tests/configs/chainspecs [#5243]
• Sepolia Shanghai configs added. Hardfork on Sepolia chain will happen at 2/28/2023 4:04:48 AM UTC. [#5280]

Performance

• Great performance improvements by @benaadams [#5186][#5196][#5206][#5216][#5251]
• Force garbage collections when visiting state trie to reduce memory pressure, e.g. in full pruning (Issue #4698) [#4699]
• Force garbage collections after finishing sync stages to reduce memory pressure [#5089]
• Reduce memory allocations when serving headers, bodies, and receipts [#5145]
• Limit memory allocations in networking code on CPU's with high core counts [#5236]
• Other code optimizations [#5213][#4623]

Gnosis

• Fixed the issue when Aura validators sometimes fork off the chain on restarts [#4679]

• Renamed xDai to Gnosis. This includes existing chain specs and configuration files. For new nodes recommended option is now -c gnosis. Old -c xdai is still supported. [#5057]

  ⚠️
  If you want to use an existing node with a new name, you need to move the database from the old directory to the one used in the
  gnosis.cfg. For example, <datadir>/nethermind_db/xdai should be moved to <datadir>/nethermind_db/gnosis.
  Same procedure applies for archive nodes, using gnosis_archive.cfg config.

v1.16.1

Release notes

This release brings important stability fixes and performance improvements, including:

• Background pruning: Reduces node latency spikes when processing blocks, leading to better attestation performance on Validator nodes
• Health check: Users will now be notified about low disk space
• Memory and performance: Performance boost and memory consumption reduction due to upgrade runtime and database engine

JSON-RPC

• Improved JsonRPC batch calls. Batch results will now be streamed. This reduces memory usage during batched calls. [#5134]
  New flags are introduced to be able to limit batched calls on node:

  • --JsonRpc.MaxBatchSize - Limits batch size for batched JSON-RPC call. The default value is 1000.
  • --JsonRpc.MaxBatchResponseBodySize - Limits max response body size when using batch requests. Subsequent requests are trimmed
    with an error response. The default value is 30MB.
    ⚠️ IMPORTANT
    We noticed that this limit is enough for most of the CL clients but there are still some unexpected behaviors with Prysm client.
    Working together with Prysm Developers to fix this since issue needs to be fixed on both sides, but there is simple workaround for this problem.
    If you will notice in Your Prysm logs warning like:
    Unable to cache headers for execution client votes" error="json: cannot unmarshal object into Go value of type []rpc.jsonrpcMessage
    restart Nethermind node using --JsonRpc.MaxBatchSize with value set to 10000.

• New engine_getPayloadBodiesByRange Engine API endpoint as a part of Shanghai hardfork. Consensus clients can use this endpoint for better performance instead of eth_getBlockByNumber [#4939]

• Fixed logs ordering of eth_getLogs when blooms are disabled [#5033]

• Fixed the trace_transaction not to contain precompile sub-traces [#4410]

Sync & Networking

• Improved state sync performance with better parallelism. This results in performance improvement -- observed state sync executes a few times faster than before. [#4921]
• Fixed issue causing a snap sync stage on Sepolia to hang on 0% for a long time [#5059]
• Fixed edge case when sync is stuck and unable to proceed further until the node was restarted [#5055]

Pruning

• In previous versions, pruning blocks block processing which can lead to increased latency from time to time on the block. In this version, pruning is moved to a background thread. This change should reduce block processing latency spikes leading to better attestation performance on Validator nodes. [#4626]

Gnosis

• Renamed xDai to Gnosis. This includes existing chain specs and configuration files. For new nodes recommended option is now -c gnosis. Old -c xdai is still supported. [#5057]

⚠️
If you want to use an existing node with a new name, you need to move the database from the old directory to the one used in the gnosis.cfg. For example, <datadir>/nethermind_db/xdai should be moved to <datadir>/nethermind_db/gnosis.
Same procedure applies for archive nodes, using gnosis_archive.cfg config.

Runtime and database

• Updated to .NET 7 [#4889]
• Updated to RocksDB v7.7. Solves issues with syncing on specific ARM CPUs. [#5065]

Health check

Added free disk space checks for the drives configured as DB locations to prevent data corruption due to disks being full. Two configurable thresholds added [#4837]:

• HealthChecks.LowStorageSpaceWarningThreshold: The percentage of free disk space below which a warning is added to the console as well as to the health checks. The default value is 5 (5% of free space).
• HealthChecks.LowStorageSpaceShutdownThreshold: The percentage of free disk space below which the client shuts down. The default value is 1 (1% of free space)

Other changes

• Added logging CPU type at startup [#5016]
• Disabled color output for CLI [#4785]
• Added Exosama network support [#5008]
• Dropped support of obsolete configurations [#5064]
• Various performance improvements (thank you @benaadams) [#5027] [#5009] [#5030] [#5079]

We'd love to hear from you, so if you encounter an issue or have any feedback, please open an issue or contact us on Discord.

v1.16.0-unstable

Release notes

This is our very first public preview (pre-release). We encourage trying this version on your nodes as it brings stability improvements and a handful of new features making your node perform even better.

To begin, you can either:

1. Download the respective binary for your platform
2. Use either of Docker images below:
   • nethermind/nethermind:unstable -- Always points to the latest unstable (pre-release) version
   • nethermind/nethermind:1.16.0-unstable

We'd love to hear from you, so if you encounter an issue or have any feedback, please open an issue or contact us on Discord.

JSON-RPC

• New engine_getPayloadBodiesByRange Engine API endpoint as a part of Shanghai hardfork. Consensus clients can use this endpoint for better performance instead of eth_getBlockByNumber [#4939]
• Fixed logs ordering of eth_getLogs when blooms are disabled [#5033]
• Fixed the result of trace_transaction to match the trace of trace_replayTransaction [#4410]

Sync & Networking

• Added support for eth/68. This is used for shard blob transactions. [#4866]
• Improved state sync performance. Use read-write lock instead of plain lock on state sync. This results in great performance improvement (on Goerli, observed state sync executes ~2 times faster than before) [#4921]
• Fixed the issue causing a snap sync stage on Sepolia to hang on 0% for a longer time (runs as expected after some time) [#5059]
• Fixed an edge case on Goerli when sync is stuck and unable to proceed further until the node was restarted [#5055]

Pruning

Currently, pruning blocks block processing which can lead to increased latency from time to time on the block. In this version, pruning is moved to a background thread. This also lowers latency on heavy pruning with multiple spins of a loop by allowing block processing to go in-between loop spins. Overall this change should reduce block processing times and make it more stable which results in better attestations. [#4626]

Gnosis

Renamed xDai to Gnosis. This includes existing chain specs and configuration files. The recommended option is now -c gnosis while the old -c xdai will be supported for some time. [#5057]

⚠️
To migrate without full resync, you need to move the database from the old directory to the one used in the gnosis.cfg. For example, <datadir>/nethermind_db/xdai should be moved to <datadir>/nethermind_db/gnosis.

Runtime and database

• Updated to .NET 7 [#4889]
• Updated to RocksDB v7.7 (solves issues with syncing on specific CPU architectures) [#5065]

Health check

Added free disk space checks for the drive configured as DB location. There are 2 configurable thresholds added [#4837]:

• HealthChecks.LowStorageSpaceWarningThreshold: The percentage of free disk space below which a warning is added to the console as well as to the health checks. The default value is 5 (5% of free space).
• HealthChecks.LowStorageSpaceShutdownThreshold: The percentage of free disk space below which the client shuts down. The default value is 1 (1% of free space)

Other changes

• Added CPU type at the very beginning of the startup log which may help debug specific nodes and reproduce potential issues more accurately [#5016]
• Disabled color output for CLI [#4785]
• Added Exosama network support [#5008]
• Dropped support of obsolete configurations [#5064]

v1.15.0

What changed?

In this version there are plenty of new changes You may find interesting like:

1. TraceStorePlugin
2. ETH/67
3. Shanghai hardfork preparation
4. Improvements & fixes in JSON-RPC, sync, metrics, networking, recovering from corruption, and more!

JsonRpc

• Add Sync stages endpoint Adds JsonRPC Debug endpoint debug_getSyncStage that reports sync stage.
• Fix eth_sendRawTransaction. returns insufficient funds when executed twice. Resolves #4829
• Fix eth_call/eth_estimateGas/eth_createAccessList to use PREVRANDAO value from specified block.

Synchronization & Networking

• eip-4938: eth/67 Add support for eth/67.
• Optimized Eth/66 implementation Use requestId instead of waiting for response from the peer. Resolves #4714
• Snap Healing Support healing of state trie during sync with snap protocol. Preparation to decommision of GetNodeData message and pre-eth/67 protocol versions on mainnet. Resolves #4324
• Fix rare issue causeing State Sync corruption. Resolves #4776
• Fix rare issues causing peers to deadlock.
• Fix Headers sync hang with negative progress.
• Fix rare issue with all peers disconnecting.
• Fix GetBlockHeaders reversed search Fix gapless reverse blockheader search. Resolves #5017
• Avoid excessive logs during Headers sync.
• Added Network.DiscoveryDns configuration option: Use tree is available through a DNS name. Keep it empty for the default of {chainName}.ethdisco.net. Resolves #4321

Shanghai hardfork preparation

• Timestamp Based Fork Activation Allows for post-merge forks to use timestamp from CL client for fork activation. Resolves #4605
• EIP-3860: Limit and meter initcode Limit the maximum size of initcode to 49152 and apply extra gas cost of 2 for every 32-byte chunk of initcode. Resolves #4588
• Add engine_getPayloadV2 Add block value to engine_getPayloadV2 result. This change allows CL clients to compare locally produced block value with builder block value, allowing for CL client to compare locally created blocks with MEV-Boost ones. Spec: ethereum/execution-apis#314

Gnosis chain

• Gnosis bootnodes Update Gnosis bootnodes to be able to sync properly on new nodes.

Plugins

• TraceStore plugin Allows to save parity like traces (trace JSON RPC module) to database during block processing and later serving them without having the state data. Makes serving relevent trace methods orders of magnitudes faster. Takes disk space. Affected methods: trace_filter, trace_block, trace_transaction, trace_get, trace_replayTransaction, trace_replayBlockTransactions. Resolves #4205 and #4143. Related PRs: #4971 Add TraceStoreConfig.DeserializationParallelization
  • Configuration:
    • TraceStore.Enabled - Defines whether the TraceStore plugin is enabled, if true traces will come from DB if possible. DefaultValue false.
    • TraceStore.BlocksToKeep - Defines how many blocks counting from head are kept in the TraceStore, if 0 all traces of processed blocks will be kept. DefaultValue 10000. Default value was chosen to have neglegible disk usage. Keep in mind that keeping full trace history on disk will take a lot of space.
    • TraceStore.TraceTypes - Defines what kind of traces are saved and kept in TraceStore. Available options are: Trace, Rewards, VmTrace, StateDiff and combinations of them or just All. DefaultValue Trace, Rewards. Default value will suffice to fully support trace_filter, trace_block, trace_transaction, trace_get methods and partial calls to trace_replayTransaction, trace_replayBlockTransactions methods. Non-default values that will include VmTrace or StateDiff will increase resource usage by a lot!
    • TraceStore.DeserializationParallelization - Maximum parallelization when deserializing requests for trace_filter. 0 defaults to logical cores, set to something low if you experience too big resource usage. DefaultValue '0'. Recommended to set to 1 or 2 on low-core public JSON RPC endpoints.

Metrics

• Gas Usage Metrics Added metrics for gas usage: GasUsed, GasLimit
• Version Metrics Added better version metric. Resolves #4860
• EIP-2159 metrics Added 4 new metrics that follow eip-2159 (ethereum_blockchain_height ethereum_best_known_block_number ethereum_peer_count ethereum_peer_limit). Resolves #4842
• Fixed Building Gauge Names.
• Fixed main metrics being wrongly updated through JSON RPC call. Resolves #4943

CLI

• Fix eth.syncing command.. Resolves #4537

TxPool

• Optimized State DB reads for accounts.

Other fixes

• Fix enode parsing when it contains DiscoveryPort. Resolves #4876
• Block Config and Mining Config separation Added separate Block creation configuration settings. Deprecated Mining configuration with added descriptions. Resolves #4836
• Fix edge case in debug_trace when memory tracing is enabled.
• DB repair on corruption Nethermind will now attempt to fix RocksDb file corruption. Requires restart.

v1.14.5

What changed?

This version is a rollback of one minor change related to Sepolia chain which resulted in unexpected regression on other chains. The issue was unnecessarily activating the SnapSync procedure on already synced nodes, that had previously configured using FastSync. This wasn't harmful for the node but was consuming resources which could have resulted in missed attestations during the processing time.
We recommend to skip version 1.14.4, and instead upgrade to 1.14.5.
