Note

Medium Risk
Required category on telemetry types and removal of mobile proxy fields are breaking for TypeScript consumers until they adapt; changes are OpenAPI-driven, not runtime SDK logic.

Overview
Release 0.59.0 bumps package version and OpenAPI/Stainless metadata; most user-facing changes are in generated TypeScript types.

Browser telemetry event interfaces now include a required category string (console, interaction, network, page, or system) on each event type, matching the API so clients can filter or group SSE events without inferring from type alone.

Mobile proxy MobileProxyConfig is narrowed for Byteful-style mobile proxies: asn, carrier, and zip are removed from create/response types everywhere they appear; city and state docs now describe provider aliases and note that observed geo may vary with carrier routing.
