26.1.0

This is a recommended, optional update for all users.

Breaking Changes

• Remove experimental CLI flag --Xenable-extra-debug-tracers. Call tracer (callTracer) is now always available for debug_trace* methods.
• RPC changes to enhance compatibility with other ELs
  • RPCs using filter parameter including eth_getLogs and trace_filter return an error if fromBlock is greater than toBlock, or if toBlock extends beyond chain head (previously returned an empty list) #9604
• Plugin API changes to BlockHeader, Log, LogWithMetadata, TransactionProcessingResult and TransactionReceipt to use specific types for LogsBloomFilter, LogTopic and Log #9556

Upcoming Breaking Changes

• RPC changes to enhance compatibility with other ELs
  • Block number parameter in RPCs will only support hex values. Support for non-hex (decimal) block number parameters is deprecated.
  • This affects several RPCs, including admin_logsRemoveCache, debug_getRawHeader, eth_call, eth_simulateV1, trace_call and more.
• ETC Classic and Mordor network support in Besu is deprecated #9437
• Holesky network is deprecated #9437
• Sunsetting features - for more context on the reasoning behind the deprecation of these features, including alternative options, read this blog post
  • ETC (Ethereum Classic) network support
  • Proof of Work consensus (PoW)
  • Clique Block Production (mining) - you will still be able to sync existing Clique networks, but not be a validator or create new Clique networks.
  • Fast Sync
• --history-expiry-prune is deprecated and will be removed in a future release

Additions and Improvements

• Update to Netty 4.2.9.Final #9587
• Update to log4j 2.25.3 #9600
• Add engine_getBlobsV3 method #9582
• Verify plugins on start #9601
• Add EIP-7778 to Amsterdam #9664
• Treat EndOfRLPException as invalid packet in peer discovery, meaning you will no longer see these exceptions, unless you enable DEBUG logs #9597

Performance

• Optimise ADD Opcode: ADD 86% faster, using new UInt256 implementation #9477
• Optimise EIP-196 AltBn128: EcAdd 33-128% faster, EcMul 8% faster #9570
• Improve getBlobsV2 by disabling HTTP response compression for engine API, with up to 10× throughput improvement observed for large numbers of blobs. #9667
• Replace BytesTrieSet with HashSet, improves CREATE, CREATE2, SELFDESTRUCT and jumpdest analysis by up to 48% #9641
• Parallelize state root computation for Bonsai #9576

Bug fixes

• Fix promotion to prioritized layer for gas price fee markets #9635

• Enhance payload selection with tx count and creation time tiebreakers #9657
• Fix mining beneficiary for BFT networks when set to zero address #9679
