Month: 2026-02 — Focused on UI stability and preserving user workflows in OpenRefine. Key work involved restoring the original Menu Column Rename/Remove Options, ensuring the data cleaning experience remains intuitive and consistent with prior releases.

OpenRefine/OpenRefine – January 2026: Stabilized core CI/build tooling, enforced Java compatibility constraints, and reduced test friction to enable safer rapid iteration. Key changes included temporary disabling of Wikibase reconciliation tests due to integration issues, reverting recent build plugin upgrades to stable versions, and tightening dependency constraints to align with the project’s Java version.

OpenRefine 2025-12 monthly highlights: Implemented release notes generation with label-based categorization, refactored SQLite connection lifecycle to prevent unintended closures, and reorganized JSONUtilities tests for proper directory placement. These changes improve release documentation clarity, reliability of JDBC-based workflows, and test maintainability, enabling safer deployments and faster QA cycles.

November 2025 focused on stabilizing the test suite and modernizing CI/infrastructure for OpenRefine/OpenRefine. Key outcomes include stabilizing database tests by addressing singleton initialization race conditions, re-enabling previously disabled tests, and upgrading the logging library to improve test observability. In parallel, we enhanced test infrastructure and CI with updates to TestNG DTD (v1.1) for compatibility and functionality, and migrated the MacOS CI runner to macOS 15 Intel, ensuring continued support and smoother cross-platform validation. These changes reduce flaky tests, shorten feedback loops, and position the project for easier future releases across environments.

Concise monthly summary for 2025-10: OpenRefine/OpenRefine delivered targeted maintenance, expanded data import capabilities, and improved dependency robustness, enabling stability, security, and broader data ingestion support. The month also included product simplifications to reflect supported features and strengthened driver loading to improve reliability across environments. Business value centers on reduced maintenance risk, enhanced data interoperability, and streamlined user experience.

OpenRefine/OpenRefine – September 2025: Delivered core reliability and maintainability improvements with four major initiatives spanning HTTP client architecture, file import robustness, exporter error handling, and modernized testing infrastructure. These changes improve stability, observability, and developer velocity, while enabling safer data imports and exports across Wikidata integrations.

August 2025 monthly summary for OpenRefine/OpenRefine focused on stabilizing deployment workflows and improving test reliability. Key CI/CD enhancements migrated artifact deployment to the OSSRH Staging API, cleaned up the snapshot publishing workflow, and reverted conflicting snapshot repository changes to restore build stability. The period also included a targeted test resource URL update to ensure tests exercise the correct endpoint, reducing flaky tests and aligning with the current infrastructure. Overall, these efforts reduce deployment risk, improve maintainability, and position the project for smoother releases with clearer responsibilities between staging and central repositories.

In 2024-10 for OpenRefine/OpenRefine, delivered targeted bug fixes and stability improvements focused on robustness and test reliability. Notable work includes expanding ToString error handling to catch IllegalFormatException and adding tests, and stabilizing facet UI tests by addressing flakiness and enabling the collapse test; these changes improve user-facing reliability and CI feedback loops, enabling faster iteration on data cleaning features.
