Mar 1, 2025March 2025 — NOS3 (nasa/nos3) delivered two primary feature efforts: (1) NOS Verification and Validation Plan Documentation Enhancements, and (2) NOS Submodule Dependency Pointer Updates. The V&V plan was drafted and iteratively refined with an architecture diagram, refined scope, updated development flow for hardware testing, and improved documentation structure; the submodule updates align dependencies to stable versions for reproducible builds. Minor editorial fixes and diffs readability improvements were performed (e.g., duplicate word fixes, Home.md cleanups, and per-PR comments). In total, 12 commits across 2 features were completed. Impact: improved testing guidance, increased maintainability, and more stable builds enabling faster onboarding and reduced release risk.
