Full Changelog: v1.1.0...v1.1.1

drain-ts v1.1.0

[1.1.0] - 2026-07-26

Added

• JaccardDrain algorithm variant (first-token-based tree with Jaccard similarity)
• DrainStream: Node.js Transform stream for real-time log processing
• RoundRobinPool: In-process round-robin TemplateMiner instances
• AbstractMaskingInstruction: Pluggable masking backends (non-regex)
• RFC 4180 CSV parser: Self-built, 40+ test vectors validated
• Playwright browser tests: Verified Drain/JaccardDrain/masking/LRU in real Chromium
• Dependabot: Weekly npm ecosystem version updates
• INI config support: TemplateMinerConfig.fromIni() for drain3.ini compatibility
• Benchmark CI: HDFS smoke test in quality pipeline
• Node 24 CI: Forward compatibility matrix
• 4 new masking presets: HOST_PORT, BLOCK_ID, PATH, SYSLOG_NUM
• getParameterList(): Drain3 API compatibility

Changed

• Profiler aligned with Drain3: custom printer, enclosing section %, batch rates, sorted output, Hz
• addLogMessage moved to DrainBase: shared by Drain and JaccardDrain (matches Python)
• PTA evaluator: <...> token normalization for masked parameter equivalence
• Benchmark: Uses GT CSV Content column as input (standard Loghub approach)
• Extended masking: 5 → 9 presets
• TemplateMinerConfig: added engine field ("Drain" | "JaccardDrain")

Fixed

• P0: Benchmark broken: parseGroundTruth() repaired (CSV header skip, EventTemplate column, RFC 4180 quoting)
• P0: Package.json types ordering: moved before import/require
• Dependabot vulnerabilities: 9 → 1 (esbuild override, brace-expansion false positive)
• Flaky benchmark test: adaptive threshold (20k → 15k logs/sec)

Security

• Dependabot version updates (no alerts)
• esbuild CVE GHSA-g7r4 mitigated via override
