Note

Medium Risk
Breaking SDK/API shape changes (removed recommendation verification, renamed evidence field, Link aliases) plus expanded payment-processor checkout contracts warrant careful client upgrades.

Overview
Release 0.106.0 bumps package/docs versions and adds one new configured API endpoint (Config Registry analysis cancel).

Browsers: PATCH updates can now send optional start_url to navigate after the update (including overriding restored profile tabs). Response start_url semantics are documented as the most recent navigation request, not only create-time.

Config Registry: Adds ConfigRegistry.Analyses.Cancel. Analyses expose nullable intent. Recommendation evidence renames last_verified_at → last_supported_at and drops the verification (verified / inferred) field from recommendations.

Vault / AgentCard: Checkout preparation is processor-bound via new AgentcardPreparedProcessor (psp) and a shared checkout environment, supporting Square, Braintree, Worldpay, Bambora, and Mercado Pago. VaultCheckoutContextParam accepts optional psp. Link card state no longer models aliases; docs steer Link checkout through fill rather than egress substitution.
