Andrew Westberg updated the Plomin Upgrade Readiness Documentation in the IntersectMBO/hf-wg-documentation repository, focusing on ensuring that documentation accurately reflected the 'Ready' status for DripDropz, NEWM, and USDM. He worked primarily with Markdown, leveraging his documentation skills to align upgrade readiness information with the current release status. This update reduced the risk of miscommunication by providing clear, up-to-date documentation that supported both release planning and upcoming audits. The work improved cross-team visibility and governance, ensuring that stakeholders had reliable information for decision-making. The depth of the update was limited to documentation, with no code or bug fixes involved.
