Sep 1, 2025September 2025 — probabl-ai/skore: No major bugs fixed this month. Delivered a key feature: Table Report Serialization Improvement and Skore Hub Integration. Refactored table report serialization by moving the _to_json logic to the skore-hub-project repository, added an offscreen backend for plotting during serialization, and serialized an extracted data portion to ensure properly formatted table reports are reliably sent to the Skore Hub. This enhances data fidelity, reduces manual reformatting, and strengthens the end-to-end reporting pipeline to the hub.

Feb 1, 2025February 2025 monthly summary for probabl-ai/skore: Delivered a UI-driven Activity Feed revamp with versioning, item annotations, and toolbar/project context; removed legacy view builder and unused routes to streamline feed rendering. Consolidated item serialization into a centralized serializers.py with a new item_as_serializable entry point, eliminating per-item as_serializable_dict methods and enabling consistent reporter serialization. Implemented maintenance and dependency upgrades, including testing framework and tooling updates to address security and stability (Vitest CVE patch, vitest/coverage-v8, CWE-346 remediation, and overall npm dependency updates).

Oct 1, 2024Concise monthly summary for 2024-10 focusing on reliability, user experience, and engineering hygiene for probabl-ai/skore. Delivered three targeted items: a bug fix to ensure reliable accordion action emission, a UX improvement to persist item reordering and auto-save layouts, and a bug fix to suppress non-interactive console noise from cross_validate. These changes reduce confusion, preserve UI state, and keep logs clean in non-interactive environments. Overall impact: increased product reliability, better user experience across views, reduced support overhead, and demonstration of strong UI event handling, state persistence, and cross-context logging.
