pipecat/changelog/3714.changed.md

• ⚠️ Refactored service settings to use strongly-typed dataclasses (TTSSettings, STTSettings, LLMSettings, and service-specific subclasses) instead of plain dicts. Each service now exposes a _settings attribute with discoverable, typed fields. Dict-based *UpdateSettingsFrame(settings={...}) is deprecated in favor of passing typed settings delta objects. For service maintainers, see changes in COMMUNITY_INTEGRATIONS.md.
