The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.3.0] - 2026-02-04

Added

  • Fullscreen ratatui TUI dashboard (default; disable with --no-tui)
    • Phase indicator, progress bar, coverage map, speed chart
    • Network, queue, storage, DB, and RPC panels
    • DOS-style splash screen with animated connection status
    • Real-time log viewer with level coloring
  • TUI log capture (circular buffer, suppresses stdout in TUI mode)
  • Per-shard compaction during fast-sync (shards compact as they fill)
  • P2P stats tracking: discovery count, genesis mismatches, sessions
  • RPC stats tracking: total requests, per-method counters, errors
  • Coverage tracker with bucket-based braille visualization
  • Peak speed tracking and follow-mode staleness detection
  • Stale-peer banning with 120s cooldown and async re-probe
  • Peer feeder rotation for fairness
  • Stall detection with peer health dump (30s threshold)
  • Sealed shard cache for fast startup on slow storage
  • db compact subcommand with progress bars, JSON logging, per-shard timing
  • db rebuild-cache subcommand to rebuild sealed shard cache
  • --defer-compaction flag to skip inline compaction during fast-sync
  • SHiNode branding: renamed binary to shinode, website (shinode.rs)
  • MIT/Apache-2.0 dual licensing
  • Workspace Cargo.toml

Changed

  • Binary renamed from stateless-history-node to shinode
  • Storage open performance: 8MB read buffers, in-memory WAL reads, cached disk stats
  • ShardMeta now tracks total_logs, total_transactions, total_receipts, disk_bytes_*
  • StorageAggregateStats for cheap cross-shard rollup (no disk I/O)
  • Read-only segment readers (prevents follow-mode file-lock crash)

Fixed

  • Follow-mode stale-peer spin-loop
  • Follow-mode head desync
  • Follow-mode log dedup

[0.2.0] - 2026-01-27

Added

  • Persist peer cache (peers.json with TTL + cap)
  • Peer warmup gate (--min-peers)
  • Peer pool warmup with async head probes
  • Fast-sync WAL batch writes (out-of-order ingestion)
  • Log events instrumentation (--log-events)
  • Optional jemalloc allocator (default feature)
  • Backpressure and memory caps for queues
  • Resume without redownload (skip present blocks, recompact dirty shards)
  • Follow mode with tail scheduling
  • Priority escalation queue for difficult blocks
  • Atomic compaction with crash recovery
  • --repair command for storage recovery
  • --log-resources for CPU/memory/disk metrics
  • AIMD batch sizing per-peer (adaptive concurrency)
  • Peer quality scoring and temporary bans
  • LRU segment reader cache

Changed

  • Compaction memory hardening (streaming WAL, serialized compactions)
  • Safe boundary switch near reorg window
  • Unified ingest pipeline with log artifacts
  • Modular codebase (run/, ui/, logging/ modules)
  • UI improvements (colored stages, compaction/sealing progress)

[0.1.0] - 2026-01-22

Added

  • CLI configuration and storage schema
  • Range sync with canonical chain tracking and reorg detection
  • Multi-peer concurrent fetching
  • NippyJar static-file persistence with idempotent writes and rollback
  • Sharded storage (v2) with per-shard WAL and out-of-order ingestion
  • JSON-RPC server: eth_chainId, eth_blockNumber, eth_getBlockByNumber, eth_getLogs
  • Graceful shutdown with checkpoint persistence
  • Verbosity levels (-v/-vv/-vvv) and progress UI
  • Chrome trace and event log artifacts
  • Chunked concurrent downloads with AIMD batch sizing
  • Follow mode with live reorg handling within rollback window
  • Shard sealing for completed ranges
