- Agents SDK v0.33.0 upgrades to Pi 1.5, cutting storage writes (~27× for long answers) and memory use while boosting throughput (up to 459 runs/sec in benchmark).
- Introduces session.watch() (replaces session.events()) and session.continue() for resuming runs, and removes retry() and parked status APIs.
- Pi 1.5 is not backward‑compatible with Pi 1.4; callers must migrate to new APIs and update deployments.
