Andrew Westberg updated the Plomin Upgrade Readiness Documentation in the IntersectMBO/hf-wg-documentation repository, focusing on aligning documentation with the actual upgrade status for DripDropz, NEWM, and USDM. He used Markdown to ensure the documentation accurately reflected the 'Ready' state, supporting both release planning and audit preparation. His work emphasized clarity and governance by reducing the risk of miscommunication between teams. The update did not involve bug fixes or code changes, but rather improved the reliability of project documentation. The depth of the work lay in maintaining up-to-date, audit-ready documentation that directly supported cross-team coordination and upgrade processes.
