What's New

Retrying pool acquire policies — Python sandbox pools now support RETRY_NEXT_IDLE and RETRY_NEXT_IDLE_THEN_CREATE, allowing acquire to skip stale idle candidates before failing or falling back to direct create. Existing policies keep their current behavior; max_acquire_retries defaults to 3. #1347
Sandbox create metrics — async and sync Sandbox.create now report fire-and-forget sandbox.create latency events to the lifecycle server. Reporting never blocks callers and can be disabled with OPENSANDBOX_DISABLE_METRICS=1. #1307
Client IP header — the SDK now best-effort detects the host intranet IPv4 and sends it as OPEN-SANDBOX-CLIENT-IP on outbound requests. Detection is cached and never overwrites a user-provided header. #1326
Attach to isolated sessions — sandbox.isolation.attach(session_id) lets stateless workers rebuild a handle for an existing execd isolated session while that in-memory session is still alive. #1295
UID mode availability — isolated session responses now expose per-mode setpriv / userns availability, and unavailable requested modes fail with 503 NOT_SUPPORTED. #1320
Exact snapshot name filtering — snapshot listing now supports an exact name filter. #1301
One-call destroy helper — Sandbox.destroy() and SandboxSync.destroy() now perform remote termination plus local cleanup, preserving the original termination exception if kill() fails. #1291

Bumped Python sandbox SDK version, default User-Agent strings, and generated lifecycle client comments for this release. #1384
