1.0.0b3 (2026-08-21)

Features Added

• FoundryStorage adapter backed by FoundryStateStore — Implements the M365 AsyncStorageBase interface on top of the durable Foundry state store KV layer. Each M365 storage key maps to a per-key FoundryStateStore with user-scoped key isolation. Hosted Activity agents default to FoundryStorage in Foundry containers and MemoryStorage for local development.

Breaking Changes

• Removed the POST /api/messages route alias. Inbound activities are served only at POST /activity/messages, which is the endpoint the Foundry platform routes to. Callers that posted to /api/messages must use /activity/messages.
• Removed public SSE keepalive helper.

Other Changes

• Fixed activity typing and claims test compatibility with M365 SDK 1.4.0. The package now handles the new py.typed marker in microsoft-agents-hosting-core 1.4.0 and the deprecated is_authenticated property.
• Updated FoundryStorage compatibility with microsoft-agents-hosting-core 1.3.0+ (target_cls is now a keyword-only argument in AsyncStorageBase.read).
