The Python SDK release v0.1.9 adds sandbox metadata patch support (async/sync) and introduces a stable Diagnostics API with log/event endpoints. It also tunes the sandbox pool's warmup backoff to reduce backend pressure.

Why it matters: Update the Python SDK to v0.1.9 to gain new sandbox metadata patch capabilities, leverage the stable diagnostics APIs for observability, and benefit from reduced backend load due to improved warmup logic.

What's New

✨ Features

Add sandbox metadata patch support to the Python SDK. Async and sync Sandbox / SandboxManager flows can now apply JSON merge-patch updates through the new metadata patch API, including add, update, and delete behavior for metadata keys. The generated lifecycle bindings and handwritten adapters were updated to match the new spec and server implementation. https://github.com/alibaba/OpenSandbox/pull/857 https://github.com/alibaba/OpenSandbox/pull/861 https://github.com/alibaba/OpenSandbox/pull/863
Add stable Diagnostics API support to the Python SDK. Async and sync clients now expose get_diagnostic_logs and get_diagnostic_events from both Sandbox and SandboxManager, backed by generated diagnostic client bindings, adapters, converters, and focused tests. scope is required for the stable API; existing legacy DevOps behavior is preserved for old clients, while the current open-source server returns DIAGNOSTICS_NOT_IMPLEMENTED for stable diagnostic requests until the backend implementation lands. https://github.com/alibaba/OpenSandbox/pull/869

🐛 Bug Fixes

Tune Python sandbox pool degraded warmup backoff to reduce backend and quota pressure during prolonged create failures. The degraded retry window now starts at an effective 30 seconds, grows up to a 1-day cap, and avoids advancing exponential attempts more than once for multiple concurrent warmup failures in the same reconcile batch. https://github.com/alibaba/OpenSandbox/pull/865 https://github.com/alibaba/OpenSandbox/pull/873
