Note

Medium Risk
Large generated Search API surface and auth/checkout type changes may affect integrators; payment (Adyen) and reauth eligibility semantics warrant careful review despite mostly additive SDK bindings.

Overview
Release 0.111.0 adds a first-class client.search surface for Search API v1: create and retrieve searches, list provider capabilities/schemas, and a typed (currently 404-until-shipped) deferred contents.fetch path. Types cover multi-provider strategies, portable filters, inline/deferred content retrieval, and per-provider native options.

Managed auth gains optional skill_mode on connection logins to disable learned domain skills, a stable completed_at on login/reauth timeline events, clearer can_reauth semantics, and a new optimistic_totp_attempt can_reauth_reason.

Vault AgentCard checkout extends prepared processors with adyen and updates checkout/preparation docs for Adyen Sessions (device handoff, environments). Browser telemetry proxy_error now includes origin_response_incomplete, restricted_route_unavailable, unknown, and optional raw_code for unrecognized header values.
