March 2025 monthly summary: Delivered key platform improvements and robust feature work across four repositories, strengthening performance, reliability, and developer experience. Highlights include coordinated platform dependency upgrades (TypeScript 5.8.2 and PineJS 21.0.3) implemented across balena-sdk, open-balena-api, and balena-cli, enabling better type safety, faster builds, and more stable tests. Added advanced data querying capability in open-balena-api with Resource Sorting by Reverse Navigation Fields, including tests for ordering with nullable relationships and missing related data to ensure robust behavior. Fixed critical TTL handling for Jobs in open-balena-api by treating a TTL of 0 as default to prevent incorrect job scheduling behavior. Streamlined dependency management and build tooling in balena-cli by deduplicating dependencies and adding a deduplicate-dependencies script to standardize and speed up installations. Fixed type definitions in grafana/k6-DefinitelyTyped (memoizee) to ensure delete() and clear() return void, accompanied by expanded tests for parameter and return types to improve correctness and DX.

February 2025: Focused on strengthening Balena CLI's SDK integration by tightening header handling to improve API identification, analytics, and reliability.
