Changelog

v1.8.0-alpha is a preview release for upstream code sync, it catches up with go-ethereum release [v1.17.3] and also removes several BSC features and fixes bugs.

Feature Removal

• core/vm: revert opcode-level optimization and fold EVMInterpreter into EVM
  The EVM opcode-level optimization (superinstruction) feature added in #3395 is removed entirely: the superinstruction interpreter, the fused opcodes and their jump-table entries are gone, and EVMInterpreter is folded back into EVM.
• core, triedb, ethdb: remove incremental snapshot (incr db) feature
  The incr downloader and merger, the incr freezers and the pathdb incr manager are all deleted.
• core/txpool, eth: remove local transaction reannounce mechanism
  Local pending transactions are no longer periodically re-announced.
• p2p: remove BSC table-layer ENR node filtering and dead bootnode bucket-size code
  The discovery table no longer filters nodes by ENR.

Code Sync

• upstream: merge geth-v1.16.9 ~ geth-v1.17.3
  Key changes from the code sync include:
• Wire protocol: eth/70 becomes the primary protocol. BSC keeps eth/68 for peer compatibility, retains TD in StatusPacket, and sends no UpgradeStatusMsg on eth/70. snap/2 groundwork landed, but only snap/1 is advertised.
• State: Verkle is replaced by the unified binary trie (UBT), with state readers split into MPT/UBT databases.
• PathDB: path-based archive with proofs, history index pruner, trienode history on existing nodes.
• EIP-7928 block access list scaffolding replaces BEP-592.
• The Amsterdam EIP set landed but stays dormant on BSC: EIP-7778, EIP-7843, EIP-8024, EIP-7708, EIP-7954, EIP-7976/7981, EIP-8037, EIP-7610.

RPC Changes

• Breaking debug_trace* structLog output follows the client-wide spec: memory words are 0x-prefixed and padded to 32 bytes, storage keys and values are 0x-prefixed, and error is omitted when empty.
• Breaking reexec is no longer accepted in the tracing config.
• eth_getLogs / eth_getFilterLogs: --rpc.rangelimit (default 5000) replaces the fixed cap toggled by --rangelimit, and exceeding it returns -32602 invalid params.
• eth_simulateV1: every call result gains a maxUsedGas field.
• New method eth_getStorageValues, which reads up to 1024 storage slots in one call.

Config Changes

• Default --cache is raised from 1024 to 4096 MB, so nodes that do not set it explicitly will use about 3GB more memory.
• Renamed: --rangelimit to --rpc.rangelimit, --override.verkle to --override.ubt.
• New: --history.trienode (serve historical state proofs, disabled by default), --miner.maxblobs, --debug.logslowblock, and the opt-in --rpc.telemetry family.
• Removed: the seven --incr.* flags plus the inspect-incr-snapshot and merge-incr-snapshot subcommands, --txpool.reannouncetime, and bootnode -network.
• Accepted but inert, warning only: --enable-bal, --rangelimit, --vm.opcode.optimize.
• config.toml: [Eth] EnableOpcodeOptimizing, [Eth.TxPool] ReannounceTime and [Node.P2P] EnableENRFilter are no longer supported.

BUGFIX

• core, eth, consensus, miner, tests: stabilize the v1.17.3 merge
• internal/ethapi, eth/filters: fix eth_simulateV1 multi-block and getLogs latest range-limit regressions
• miner, core/vm: fix MEV bid gas accounting and EVM stack-arena double-release
• core/txpool: fall back to an empty state when head state is unavailable
• eth/downloader: fix legacy snap sync regressions from the v1.17.3 merge
• miner, core: fix mining prefetch rate-limiting broken by shadowing
• miner: make MEV bid per-builder quota admission atomic
• consensus/parlia: only blind-sign legacy system txs

Others

• core/filtermaps: update BSC mainnet and chapel log index checkpoints
• cmd/faucet: add United Stables ($U) testnet token
