Nov 1, 2025November 2025 – cocoindex monthly summary: Delivered cross-module utilities, strengthened type safety, stabilized dependencies, and improved CI/Examples reliability to drive stability and faster delivery across teams. The month focused on extracting is_courinte_fn into a shared utility, tightening type hints with TypeIs, pinning pyarrow to >=19.0.0 for lancedb, bumping example cocoindex to >=0.3.9, introducing sanity checks to verify Python vs engine versions, and extending Finterprint for raw bytes optimization. Also resolved key bugs in BAML PDF handling, cleaned up example code, and improved batched function input handling. These changes reduce runtime errors, simplify maintenance, and improve platform compatibility.
