Aug 1, 2025August 2025 monthly summary focusing on delivering three core features, improving data hygiene, and strengthening security posture through API unification. Key outcomes include centralized configuration management, a new soft-deleted data cleanup job, and an API key management refactor to V4 with standardized permission checks and removal of deprecated versions. Also, security/access controls were hardened via an authorization fixes workstream supporting roles, permissions, users, members, and apikeys. The efforts reduced deployment complexity, controlled database growth, and improved maintainability across environments.
