Release notes
This is a patch release on top of 1.39.0 with a round of bug fixes and reliability improvements across snap sync, networking, JSON-RPC, and the experimental Flat DB.
Overview
Full diff: https://github.com/NethermindEth/nethermind/compare/1.39.0...1.39.1
8 changes since 1.39.0. Highlights:
- Flat DB (experimental, opt-in) — fixed a disposal race between shutdown and in-flight trie-warmer jobs (#12237)
eth_simulateV1now bounds the total block expansion, not just each inter-block gap (#12210)- Bad-block store is bounded by entry count as intended, instead of comparing against the DB byte size (#12225)
- Quieter logs — RLP limit diagnostics toned down (#12130)
Highlights
Sync
- Reject malformed snap range proofs instead of throwing (#12187)
- Verify the hash of trie nodes recovered via snap heal (#12200)
Networking
- Reject zero-size RLPx frames in
ZeroFrameDecoder(#12202) - Tone down RLP limit logging (#12130)
JSON-RPC & Engine API
- Bound
eth_simulateV1total block expansion, not just each gap (#12210) - Side-effect-free invalid-chain query and atomic node get-or-create in the invalid-chain tracker (#12208)
Storage & state
- Bound
BadBlockStoreby entry count, not DB byte size (#12225) - Flat DB (experimental, opt-in): lease the read-only bundle for in-flight trie-warmer jobs (#12237, fixes [#12079])
