February 2025: Delivered significant feature work, quality improvements, and documentation updates across two primary repositories. In MicrosoftDocs/powerbi-docs, we implemented the Data Freshness Review System (v1–v6), boosted Acrolinx quality with threshold improvements, added PM/community clarifications for templates, and refreshed documentation, assets, and freshness-related content (including the Desktop changelog, code samples, and images).
