v0.3.0

Summary

Highlights

• New morph_ RPC namespace (#106) — adds morph_getTransactionHashesByReference,
  backed by a new morph-reference-index crate (dedicated MDBX store) and an ExEx
  that indexes Morph-tx references from the Jade activation block onward. Ships
  with startup backfill + reorg-aware reconcile, gated readiness, and
  lag-threshold guards. Compatible with geth-style hex-quantity offset /
  limit on the wire.

• Build-profile gradient and production-deploy retune (#104) — adds explicit
  dev / release / profiling / maxperf / bench / hivetests profiles
  to the workspace. Production deploys (Dockerfile, EC2 build, tag-push release
  CI) now default to the profiling profile, which captured ~80% of maxperf's
  hot-path gains in our benchmarks while avoiding maxperf's ERC20 long-tail
  regression. x86_64 release artifacts now target the x86-64-v3 baseline
  (Haswell+ / Excavator+) plus pclmulqdq.

Breaking Changes

• Removed engine_appendBatchSignature and BatchSignature (#105) — the
  consensus layer (tendermint / morphnode) stopped calling this method after
  batch generation moved out of the consensus path into the tx-submitter
  (morph-l2/go-ethereum#319, morph-l2/tendermint#35,
  morph-l2/morph#939). Operators must run a tendermint / morphnode build
  that no longer issues the call.

Notable Cleanups

• refactor(evm): removed unreachable apply_curie_hard_fork dead code; every
  Morph chain config sets curieBlock = 0 and the L1GasPriceOracle Curie slots
  are initialized post-launch via a regular transaction (mainnet block 863) (#101).
• fix(clippy): silenced unnecessary_sort_by (#100).

Compatibility

• No state-DB schema changes for the main reth datadir.
• New optional reference-index DB at <datadir>/morph/reference_index/ —
  created and backfilled on first start; takes a few minutes for the
  post-Jade range to become queryable. The RPC returns
  -32000 "reference index initializing" until ready.

v0.2.2

Summary

This release introduces Prometheus metrics for observability, fixes --version to correctly display morph-reth identity, and
updates CI dependencies.

Highlights

• Engine API & Payload Builder Metrics: Added Prometheus counters, histograms, and gauges for Engine API calls
  (newL2Block, assembleL2Block, fork_choice_updated) and payload building (block gas, tx counts, build duration). Enables
  Grafana dashboards and alerting for node operators.
• Version Metadata Override: morph-reth --version now shows morph-reth's own version, commit SHA, and build info instead
  of the upstream reth fork values. The -dev suffix is automatically appended for non-tagged builds.
• CI: Bumped docker/build-push-action from v6 to v7.

All Changes

• feat(metrics): add Prometheus metrics for Engine API and payload builder (#97)
• feat(node): override version metadata with morph-reth info (#95)
• chore(ci): bump docker/build-push-action from 6 to 7 (#96)

v0.2.0

Summary

This is the first public release of morph-reth, the Reth-based execution client for Morph L2. It establishes the complete CI/CD
infrastructure and delivers a series of correctness fixes validated against Morph mainnet and Hoodi testnet.

New Features

• eth_config RPC method — Morph-specific chain configuration endpoint (#72)
• Jade fork activation timestamps — Mainnet and Hoodi hardfork schedules are now set (#51)

Bug Fixes

• BLOCKHASH opcode — Aligned with Morph geth semantics (chain_id || block_number hash) (#38)
• State root validator — Restored pre-Jade ZK-trie state root hook (#47)
• L2 header alignment — Fixed field mismatch between assemble and import paths (#58)
• Trace replay — Fixed Morph trace replay on Cancun-active chains (#57)
• L1 message gas price — baseFee now returned as effectiveGasPrice for L1 messages (#60)
• Payload serialization — nextL1MessageIndex serialized as bare uint64 instead of hex (#73)
• EVM — Removed unnecessary EIP-7825 tx gas limit cap override (#79)
• Chainspec — MORPH_BASE_FEE used as genesis default (#74)

• Security — Fixed lz4_flex memory leak (GHSA-vvp9-7p8x-rfvv) and keccak ARMv8 unsoundness (GHSA-2326-pfpj-vk5v) (#41, #53)

Infrastructure

• Multi-platform Docker images (linux/amd64, linux/arm64) — build time reduced from ~200min to ~20min via cross-compilation
