Mar 1, 2026March 2026 (open-condo-software/condo): Delivered platform-level NATS Streams support, enabling robust, secure, real-time messaging across services. The work included refactoring to move NATS behind adapter classes, migrating to the new websocket NATS API, and tightening access checks and environment configuration for the NATS service. Significant CI/CD improvements accompanied the feature: enabling NATS tests in CI, updating dependencies, and addressing stylelint, lint, and security issues to ensure production-readiness. The initiative establishes a scalable messaging backbone, improves multi-tenant isolation and observability, and reduces operational risk for real-time workflows.
