Month 2026-03 — Key features delivered include API Security Hardening and Token Policy Framework, Immediate DAG Run on Unpause (Airflow 3.0 style), and Structured Logging with Per-Logger Log Level Configuration. These changes deliver stronger security posture, improved user experience for unpaused DAGs, and enhanced observability across services. 1) API Security Hardening and Token Policy Framework: Restructured the Execution API security to leverage FastAPI Security scopes with a three-layer approach: a cached crypto validator, a route-aware authorization layer, and a custom route class that precomputes allowed token types. This foundation enables per-endpoint token type policies and paves the way for workload tokens on selected routes. (Commit df4cb30b116c8628afc465876e08d58f2bcb897b) 2) Immediate DAG Run on Unpause (Airflow 3.0 style): Made start_date optional for continuous schedules so unpausing a DAG triggers immediate execution using the current time, aligning with Airflow 3.0 design philosophy. (Commit 191eca02c136d0b1330ff2cf60789b0beb47dbfc) 3) Structured Logging + Per-Logger Log Level Configuration: Introduced structured JSON logging for API server output and added per-logger log level configuration to tailor verbosity without affecting global settings. Adjustments include changes to Gunicorn/Uvicorn logging integration and a per-request structured event model. (Commits 0266b0b14eb6312382ae6af7b033084bc83bb9ff, eca09a04b5a1fe91564eb1d881af5f1be351a6ee) 4) Additional impact and groundwork: The changes establish a foundation for workload-token support and improve traceability across the API surface, while progressively aligning with Airflow 3.0 expectations. Major bugs fixed: No critical bugs reported this month. The focus was on implementing the new security model, improving unpaused DAG behavior, and enhancing observability to support future reliability and maintenance. Overall impact and accomplishments: Strengthened security posture, improved DAG UX with immediate start behavior, and higher operational visibility through structured logging. These workstreams collectively reduce risk, accelerate incident response, and facilitate future feature work around workload tokens.
