Oct 1, 2025October 2025 monthly summary for equinor/ecalc focusing on UX-driven quality improvements and robust YAML handling. Delivered two critical changes: (1) improved the time series data validation error UX by adding a hint about the expected date column name, reducing user confusion and speeding resolution, and (2) fixed an issue where uploading an empty item in YAML caused an error, ensuring empty fields are handled correctly and updating documentation. These changes reduce support overhead, improve data integrity, and streamline developer onboarding.

Sep 1, 2025September 2025 monthly summary for equinor/ecalc. Delivered a stronger, more reproducible release pipeline and improved security posture while preparing for libecalc v11.0.0. Key outcomes include: a dedicated CI workflow to freeze Python dependencies on a separate branch (replacing a non-functional workflow) to improve stability and environment reproducibility; security-focused dependency upgrade upgrading @mdx-js/react from 3.1.0 to 3.1.1 without feature changes; and release readiness for v11.0.0 with documentation updates, changelog entry, and release notes sidebar adjustments. These changes were implemented via commits: 9e022cd24ac3698a40bbe2ce5270c277936dd38b, 2ada71f198407dafb6e81f57a41a3e97fb12c5ca, e603b56e26a35c19f5238d033f95c2395b65b449, a1832136dc05f895edca79e5b1d5b6a4eb8bc1fd.

May 1, 2025May 2025 monthly summary for equinor/ecalc: Implemented Data Ingestion Robustness Enhancements to strengthen the reliability and quality of time-series data ingestion. This included stricter validation for time series resource types, improved handling of missing values in facility resources, and enforcement of essential headers (e.g., SPEED) to prevent processing errors. Two critical commits underpinned these improvements: 'fix: validate reading of resources (#881)' and 'fix: key error speed (#896)'. Impact: reduced ingestion failures, cleaner datasets for downstream analytics, and more resilient data pipelines. Technologies and skills demonstrated: defensive data validation, error handling, header-driven validation, and overall ETL pipeline hardening.
