Nov 1, 2025November 2025 highlights stability, CI improvements, and regression-testing readiness for IBM/data-prep-kit. Key changes include cleaning up Ray initialization to reduce runtime coupling, refactoring the multimodal directory for clearer image transforms, and expanding the workflow/build-system to improve test coverage and release readiness. Several CI experiments were conducted, including feature flags for selective workflows, with stability maintained through timely rollbacks and configuration hygiene. Release preparation for version 1.1.6 and new regression-testing releases (dev1/dev2) establish a solid path to scalable data preprocessing and reliable production deployments.

16 Commits • 14 Features
Sep 1, 2025September 2025 focused on unifying and hardening the core data transformation framework, tightening security, and advancing release readiness and Granite Docling integration. The Binary Transformation Framework was refactored into an abstract base with centralized handling and validation, with unified transform interfaces and improved empty-input behavior to align with downstream processing. Security logging was hardened by sanitizing credentials. Release readiness was advanced with version bumps, Next Release field updates, and Docker tag preparation. Granite Docling (VLM) pipeline support was added to docling2parquet, accompanied by tests, a dedicated notebook, dependency updates (mlx-vlm), and test data/expected outputs aligned to the new pipeline.
