Worked on the lsst-ts/ts_xml repository to enable C++ compilation for the M1M3TS and MTVMS components by updating build configurations, thereby supporting cross-platform compatibility on Apple Silicon. The approach involved careful build-system configuration and the addition of a feature news entry using RST to document new C++ runtime asset flags, ensuring clear communication of changes for future releases. The work focused on C++ development, XML schema updates, and thorough documentation practices, with attention to commit traceability and release readiness. No bugs were identified or fixed during this period, reflecting a targeted effort on feature enablement and maintainability improvements.
