Note

Medium Risk
SDK contract changes touch payment checkout preparation and rename/remove Config Registry response fields (verification, last_verified_at), which can break typed client code even though behavior is API-driven.

Overview
Release 0.106.0 bumps package/version metadata and documents four feature areas in the changelog (Config Registry polish, browser start_url on update, multi-processor AgentCard prepare-checkout, and unrelated backend placement notes).

Browsers: client.browsers.update now accepts optional start_url to navigate after the patch (overrides profile-restored tabs when both are set; best-effort navigation). Browser session types now describe start_url as the most recent navigation request, not creation-only.

Config Registry: Adds client.config_registry.analyses.cancel for async cancellation of running analyses. Analysis exposes optional intent. Recommendation/evidence modeling shifts from “verified” wording to recommended support: Evidence.last_verified_at becomes last_supported_at, and Recommendation.verification is removed (with clearer match_scope docs).

Vault / AgentCard: Checkout preparation is processor-bound, not Square-only. New AgentcardPreparedProcessor and optional psp on checkout context; preparations/responses include psp, and environment adds shared for some processors. Link card state drops aliases and docs steer checkout toward fill without egress substitution/alias fallback.
