Worked on the IntersectMBO/cardano-updates repository to deliver readiness for the DBSync pre-release 13.6.0.0, focusing on supporting a mainnet upgrade and ensuring compatibility with node-10.1.0. The approach centered on thorough documentation and release management, including the initiation and tracking of hard fork testing to reduce upgrade risk. Used Markdown to produce detailed progress reports and validation test results, maintaining clear traceability through versioned commits. No major bugs were reported during this period, and minor issues were documented for future sprints. The work accelerated time-to-production and emphasized disciplined testing and collaborative release preparation for the upcoming mainnet deployment.
