June 2025: Focused on stability, reliability, and data integrity across AAP services. Key outcomes include reverting unstable library bumps to stable KTOR/Jackson/OpenAPI, removing explicit Hikari pool sizing to rely on proven defaults, and hardening NORG integration to correctly handle multiple parent units. These changes reduce incident risk, simplify configuration, and improve downstream data processing.
