• Pre-match normalization: automatic case, whitespace, and punctuation normalization before comparisons

v0.2.6 (February 2026)

Source Adapters

• Added Source.from_warehouse(name, conn, query) for SQL databases
• Added Source.from_dbt(name, project_dir, model) for dbt models
• Improved Source.from_pandas() with automatic type inference

v0.2.5 (January 2026)

Performance

• 3x faster reconciliation on datasets > 100K records
• Reduced memory usage for large blocking passes
• Parallel comparison within blocks (multi-threaded Rust engine)

v0.2.0 (January 2026)

Initial Public Release

• Core reconciliation engine (Rust, via PyO3)
• Source adapters: CSV, Pandas
• Matching rules: exact, jaro_winkler, levenshtein, soundex, composite
• Survivorship strategies: source_priority, most_recent, most_complete
• Decision thresholds: match_threshold, review_threshold
• Spec validation with detailed error messages
• Golden record output as Pandas DataFrames
• Platform support: Linux x86_64, macOS Intel, macOS Apple Silicon

Cloud Platform

February 2026

January 2026

• Cloud reconciliation: Upload sources and run reconciliation in the cloud
• Identity graph: Persistent, queryable graph of entity relationships
• API authentication: JWT-based auth with tenant isolation
• Audit logs: Immutable log of all reconciliation runs and match decisions
