Sep 1, 2025September 2025: Implemented code ownership governance for npm/yarn files in SpecterOps/BloodHound by adding .github/CODEOWNERS rules and assigning ownership for package.json, package-lock.json, yarn.lock, and yarn directories/config files. This clarity reduces ambiguity, speeds up code reviews, and improves dependency configuration integrity across releases.

May 1, 2025May 2025 monthly summary for SpecterOps/BloodHound. Key features delivered: Back Button Support flag removed; UI refactor to V2; routing migrated to BrowserRouter; tests updated to remove mocks tied to the flag. Major bugs fixed: SQL migration corrected to properly enable back_button_support and set it as non-user-updatable, ensuring correct flag configuration in the database. Impact and accomplishments: Reduced feature-flag debt, stabilized UI and routing, safer migrations, and improved test reliability. Technologies demonstrated: React UI refactor (V2), BrowserRouter migration, database flag configuration, and SQL migration correctness. Business value: cleaner codebase, faster future enhancements, and more predictable deployments with fewer flag-related risks.
