February 2026 monthly summary for google/flatbuffers. Delivered a new TypeScript optional-field handling option in flatc (--ts-undefined-for-optionals), enabling generation of TypeScript where optional fields are undefined instead of null. This improves TS compatibility, clarity, and downstream reliability for TypeScript users. The work included end-to-end tests and generated test artifacts to validate the behavior, and addressed an existing issue (#7656). Formatting and test hygiene were maintained with clang-format updates and test script refinements. Collaboration note: co-authored by José Luis Millán.

Monthly summary for 2025-08 focusing on grafana/k6-DefinitelyTyped. Delivered TypeScript Type Definitions and Refactoring for sdp-transform, including updated interfaces and new types to more accurately model SDP messages, improving type safety and alignment with current specifications. Work consolidated in PR #73399: 'Update and fix @types/sdp-transform' and bump to version 2.15 by @ibc. This effort enhances downstream developer experience, reduces type-related issues, and positions the project for smoother integration with evolving SDP tooling.
