Jan 1, 2025January 2025 monthly summary for neo4j/graph-data-science-client focused on delivering user-visible improvements, reliability, and maintainability across the codebase. The month centered on UI/UX enhancements, observability, compatibility with newer runtimes, and code quality improvements to support faster incident resolution and easier onboarding for new contributors. Key deliverables and outcomes: - UI and Progress Display Enhancements: Improved session list rendering using a pandas DataFrame, with status/progress bars and refresh indicators; added display of the currently running subtask in the progress bar and ensured the progress bar remains visible even when jobId is absent. - Observability for Remote Projections: Introduced logging support for remote projections to aid troubleshooting and incident analysis. - Compatibility, Docs, and Versioning: Updated GDS server version compatibility table and docs version references; added Python 3.13 compatibility and pandoc 3.6.2 to the docs/tooling stack; expanded changelog and doc updates. - Graph/List and Config Enhancements: Allowed string values for the graph filter parameter in gds.graph.list; permitted empty configurations for ensure_job_id; improved handling for missing type fields. - Quality, Tests, and Maintenance: Consolidated test stability/coverage improvements; extensive code formatting and signature cleanup; removed resolved TODOs; improved user-facing wording across messages. Impact: These changes reduce time-to-diagnose and fix-incident duration, improve user experience for long-running projections, and increase maintainability and future-proofing with newer Python compatibility and better observability. Top 3-5 achievements (highlights): - UI/Progress: pandas-based session list with status and subtask progress visuals; robust progress bar behavior. - Observability: remote projection logging for troubleshooting. - Compatibility/Docs: Python 3.13 support and updated docs/pandoc tooling. - Graph/Config: flexible graph filters and ensure_job_id handling. - Quality: test stabilization, formatting, and signature cleanup.
