Released v0.9.0 — 2026-10-07 Focus: Performance and correctness hardening. • Materialized statistics CTE, hoisted casts, and partition pre-filtering cut file listing ~400×: 2,703 → 6.8 ms. • UPDATE pushes predicates into Parquet; keyed DELETE reads only predicate columns (~10 KB vs. 14 MB). Catalog-based counts with delete files; one read per cold footer. • Added DuckLake comments/tags, more object-store URL schemes, batch file registration, and snapshot metadata. github.com/datafusion-con…
