Changelog

ElevenAgents

• Test-specific tool mocks: Agent simulations and unit tests can now define tool_mock_overrides, keyed by tool ID, to replace shared mocks for one test. ToolResponseMockConfig also adds optional is_error (boolean, default false) so a mock can exercise tool-failure paths.
• Translated workflow messages: Literal Say node messages add text_translations, a map of language keys to TranslatedString objects. The field is optional on input and required on output, so strict response validators must accept it.
• Conversation version filters: List conversations and Text search conversation messages add the optional version_id query parameter (string) to filter results by agent version.
• Knowledge base system tool: Agent configuration adds a knowledge_base system tool with configurable enabled_strategies (SearchStrategy[]). Agent knowledge base RAG queries add optional use_agent_defaults (boolean, default true); set it to false to use neutral retrieval settings while retaining the agent’s embedding model.
• Agent voice activity detection: Agent create, update, response and workflow-override schemas add vad configuration. VADConfig currently supports background_voice_detection (boolean, default false).
• WebSocket custom LLMs: CustomLLMAPIType adds websocket.
• File memory controls: Widget file-input configuration adds max_files_in_memory (integer, 1–30, default 10). Files beyond the limit are summarized and released from memory; max_files_per_conversation must be -1 or at least the memory limit.
• DTMF input redaction: DTMFInputConfig adds optional redact_input (boolean, default false) to replace caller keypad digits in transcripts, conversation logs and analysis. Digits repeated by the agent or passed to tools remain unchanged.

Speech to Text

• Realtime entity detection: Scribe v2 Realtime adds the entity_detection query option. It accepts all, one entity type or category, or an array of types and categories, and emits detected entities in committed_transcript_entities events. See the entity detection guide for supported categories.

Voices

• Voice replication across data residencies: Added POST /v1/voices/{voice_id}/replicate-to-isolated-environment for copying an Instant Voice Clone or Voice Design voice to a workspace in the same consolidated billing group. Requests require target_workspace_id (string) and accept preserve_voice_id (boolean, default true); responses return the target voice_id.
• Character metadata: Character responses add recommended_voice_ids (string array, default []), metadata adds nullable role (CharacterRole), and CharacterAge replaces middle-aged with middle_aged.

SDK Releases

Packages

• @elevenlabs/client@1.16.0, @elevenlabs/react@1.11.0, @elevenlabs/types@0.18.0, @elevenlabs/react-native@1.2.17 and @elevenlabs/convai-widget-core@0.15.0 - Added onAgentReasoningResponsePart, which receives streaming agent reasoning events with start, delta and stop types.
• @elevenlabs/convai-widget-core@0.15.0 and @elevenlabs/convai-widget-embed@0.15.0 - Added show_resize_button and the show-resize-button embed attribute. Set either to false to hide the widget header’s expand and collapse control.
• @elevenlabs/client@1.17.0, @elevenlabs/react@1.12.0, @elevenlabs/types@0.19.0, @elevenlabs/react-native@1.2.18 and @elevenlabs/convai-widget-core@0.15.1 - Added the enableLogging option to Scribe.connect and useScribe. Setting it to false starts an enterprise zero-retention session. The Scribe session_started type now reports enable_logging; the unused disable_logging field was removed.

MCP Server

• v0.12.1 - Includes the v0.11 tool updates and a dependency refresh that resolves 44 security alerts.
• v0.11.0 - Added simulate_conversation with configurable simulated-user behavior, evaluation criteria, transcript output and pass/fail analysis. The speech_to_text tool now defaults to scribe_v2, and voice_clone now sends audio file contents instead of path strings.
