The SDK shipped three major versions in quick succession, fundamentally reshaping the API surface. In late March, @elevenlabs/client and @elevenlabs/react introduced breaking changes: the Input class disappeared in favor of methods like getInputByteFrequencyData() and setMicMuted() on the conversation object, while useConversation now requires a ConversationProvider ancestor and exposes granular hooks (useConversationControls, useConversationStatus, etc.) instead of a monolithic return shape. @elevenlabs/react-native underwent a complete rewrite, ditching its custom LiveKit-based provider to re-export the React package's API, with side-effects on import to polyfill WebRTC and configure native audio. After stabilization in early April, the SDK focused on multimodal and feature refinement: sendMultimodalMessage surfaced in hook controls, tool response mocking landed in the client, and the widget gained intelligent language auto-selection from localStorage and browser preferences. A late-April fix addressed Node.js ESM compatibility by switching to explicit .js file extensions in imports.
