2.0.0b11 (2026-08-05)
Features Added
- Added a shared
experimentaldecorator for marking Agent Server preview feature surfaces with docstring notes and one-time runtime warnings. The resilient task primitive and Foundry storage public APIs are now marked experimental.
Breaking Changes
- Removed the unused public
AgentServerHost.sse_keepalive_streamhelper.
Other Changes
- The per-turn task
timeouthard ceiling was raised from 1 day to 7 days. The default when unset is still 1 day; a supplied value may now raise the per-turn budget up to 7 days. A value greater than 7 days (or a negative value) is still rejected at registration (ValueError, fail-fast, not clamped). This remains a per-turn cap only — multi-turn chains still live indefinitely across turns (the budget resets each turn).
