ApexBase v1.26.0

2026-07-29

Compare with v1.25.0

• Harden V4 .apex file validation at open time: verify header/footer offsets, schema column counts, visible row counts, and row-group bounds, returning a clean corruption error for truncated or malformed files instead of risking a Rust panic
• Strengthen SQL DDL/DML validation and read-your-write consistency across INSERT, UPDATE, DELETE, schema changes, cached reads, numeric range statistics, and zone maps, including clearer errors for invalid types, column arity, and unsafe schema mutations
• Preserve SQL null semantics across expressions, grouping, aggregates, Arrow/Pandas conversion, temporary CSV tables, and projected row reads
• Improve vector topk_distance execution by validating query vectors and dimensions, applying filters before distance computation, and avoiding unnecessary reads of wide or unused BLOB columns in TopK JOINs
• Add binary parameter binding for single-query topk_distance calls, eliminating vector text interpolation in the Python API
• Extend full-text search with Boolean AND/OR/NOT expressions, configurable fuzzy matching, safer index reconfiguration, and richer index status information
• Add ApexClient.execute_batch_parallel for independent read-only SQL statements while retaining ordered execute_batch semantics for scripts
• Improve BLOB projection, CREATE TABLE AS SELECT, INSERT ... SELECT, Lance vector/temporal round-trips, correlated text subqueries, and process-safe concurrent writes
• Expand regression and performance coverage for storage corruption handling, DML and null edge cases, FTS, TopK JOINs with BLOB data, parallel batch execution, and Arrow batch-result APIs
• Update the Rust crate and Python package version metadata to 1.26.0
