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: 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_simulateV1 now 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_simulateV1 total 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 BadBlockStore by 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)
