Note

Medium Risk
Managed-auth submit and response shape changes affect authentication integrations; legacy fields remain but callers should migrate to canonical fields/choices.

Overview
Release 0.80.0 bumps package version metadata and refreshes the OpenAPI spec reference; most functional change is in managed auth client types aligned with the updated API.

Managed auth responses and SSE follow events now expose canonical fields and choices (with new ManagedAuthField / ManagedAuthChoice types), documented as preferred over legacy discovered_fields, MFA/SSO/sign-in option shapes. Submit requests add field_values and selected_choice_id while keeping older submit fields during deprecation. Auth connection timeline events gain browser_session_id.

CI runs-on for build/lint/test now uses depot-ubuntu-24.04 for any repo under the stainless-sdks/ org prefix, not only kernel-go. Tests use a realistic proxy check URL example (https://example.com).
