February 2026

5 Commits • 3 Features

Feb 1, 2026

February 2026: Delivered key features across ApiCommonModel and ApiCommonWebsite, driving improved configurability for RNA-Seq/WGCNA analyses, AI-assisted interpretation guidance, and platform stability. Replaced deprecated eda_notebook_type with a structured propertyList, added missing WGCNA analysis specifications, enhanced help text for Claude Sonnet 4.5 usage, and upgraded genomics-site to 1.3.25 for bug fixes and performance improvements. These changes enable clearer analysis parameterization, more reliable data queries, and better alignment with user workflows, contributing to faster research insights and improved researcher experience.
