v0.4.1

Added

• lance_vector_search now supports the nprobs and refine_factor parameters.

Fixed

• Fixed vector search to accept query vectors as DuckDB ARRAY types (e.g. FLOAT[dim], DOUBLE[dim]) in addition to LIST types.
• Fixed COPY ... (FORMAT lance) to normalize LIST vector columns so they can be used with vector search and indexing.

---

Commits

• fix: Fix DIM support in vertor search by @Xuanwo in #119
• feat: Add nprobs and refine_factor support by @Xuanwo in #120
• Bump to version v0.4.1 by @Xuanwo in #121

Full Changelog: v0.4.0...v0.4.1

v0.4.0

Added

• Transactional DELETE support (honors BEGIN/COMMIT/ROLLBACK).
• Support UPDATE without a WHERE clause to update all rows.
• Predicate pushdown for string functions: starts_with, ends_with, contains.
• Support CREATE INDEX ... ON ns.main.tbl(col) USING BTREE on attached namespaces.

Changed

• Breaking: Object store credential/configuration now uses CREATE SECRET (TYPE LANCE, ...) (instead of TYPE S3).
• Aligned directory and REST namespace behavior.

Fixed

• UPDATE ... SET col = DEFAULT now works correctly.

Full Changelog: v0.3.0...v0.4.0

v0.3.0

Added

• COPY ... TO ... (FORMAT lance, ...) writer for creating and appending Lance datasets.
• Directory and REST namespaces via ATTACH ... (TYPE LANCE, ...).
• DDL support for attached namespaces: CREATE TABLE, CTAS, DROP TABLE, ALTER TABLE (schema evolution and comments).
• DML support for attached namespaces: INSERT, UPDATE, DELETE, TRUNCATE TABLE.
• Index DDL on dataset URIs: CREATE INDEX, SHOW INDEXES, DROP INDEX (vector, scalar, and full-text).
• Additional scan pushdown and planning improvements: LIMIT/OFFSET, TABLESAMPLE SYSTEM, LIKE, regexp_matches,
  IS (NOT) DISTINCT FROM, and expanded type coverage (including timestamp/decimal/struct filters).
• DuckDB rowid / Lance _rowid support for scans, enabling point-lookup and rowid-based optimizations.
• Basic scan statistics for improved planning.

Changed

• Scan and maintenance helper table functions are internal-only; the user-facing surface is replacement scan, namespaces,
  search functions, and the lance copy format.
• Improved parallelism for writing datasets.
• Refined test coverage and organization for sqllogictests.
