### ElevenAgents

- **SIP logs**: SIP signaling logs are now available for SIP trunk calls in conversation history and phone number settings. Logs include the SIP call ID, phone numbers, addresses, transport, message direction, raw messages and errors to help debug call setup and routing issues.
- **Knowledge base document updates**: New API to list indexed (RAG) chunks for a document. Documents can also be edited in place: rename the item and, for text-based documents, update the body without re-uploading the file. (File-based documents still use the existing replace-file flow where applicable.)
- **SMS conversation metadata**: Added SMS support to conversation metadata with `SMSConversationInfo`, `sms` as an authorization method and `twilio_sms` as a conversation initiation source.
- **Agent configuration updates**: Added background music configuration schemas, alerting monitor configuration, 2D layout fields, widget file upload configuration, and new LLM options `gpt-5.4-mini`, `gpt-5.4-nano`, `gpt-5.4-mini-2026-03-17` and `gpt-5.4-nano-2026-03-17`.

### Workspaces

- **API request analytics**: Added a workspace analytics endpoint for querying API requests with time range, filtering, search, sort and limit controls.
- **API key IP allowlisting**: Added `allowed_ips` to service account API key create, edit and response schemas. Create requests accept an array of IP addresses or CIDR ranges, or `null` to allow all IPs. Edit requests also accept `clear` and `no_update`.
- **Workspace permissions**: Added `conversational_ai_read` and `voice_design` to workspace group permissions.

### Voice Design

- **Voice preview migration**: Deprecated `POST /v1/text-to-voice/create-previews`. Use [Design a voice](https://elevenlabs.io/docs/api-reference/text-to-voice/design) to create previews, then use the returned `generated_voice_id` when creating a voice.

### Voice Changer

- **WAV output formats**: Added `wav_8000`, `wav_16000`, `wav_22050`, `wav_24000`, `wav_32000`, `wav_44100` and `wav_48000` to the `output_format` query parameter on speech-to-speech conversion.

### SDK Releases

#### Python SDK

- [v2.47.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.47.0) - Regenerated the SDK for the May 12, 2026 API schema. The release adds typed support for RAG chunk listing, file document updates, workspace API request analytics, service account API key IP allowlisting, phone number agent configuration fields, webhook request headers, voice metadata moderation, new LLM options and updated speech-to-speech output formats.

#### JavaScript SDK

- [@elevenlabs/client@1.6.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.6.0), [@elevenlabs/react@1.5.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact%401.5.0), [@elevenlabs/react-native@1.1.6](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact-native%401.1.6) and [@elevenlabs/types@0.12.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Ftypes%400.12.0) - Added native mute and unmute support to Scribe realtime STT. `RealtimeConnection` now exposes `mute()`, `unmute()` and `isMuted`, and `useScribe` exposes matching state and callbacks.

The React package also allows `useScribe` microphone `deviceId` to use full `ConstrainDOMString` constraints.
- [@elevenlabs/convai-widget-core@0.12.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.12.0) and [@elevenlabs/convai-widget-embed@0.12.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.12.0) - Added file upload support to the embedded ElevenAgents widget.

- [@elevenlabs/convai-widget-core@0.12.3](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.12.3) and [@elevenlabs/convai-widget-embed@0.12.3](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.12.3) - Fixed transcript ordering when user and agent messages share the same `event_id`, so voice and DTMF turns render the user transcript before the agent message.
- [@elevenlabs/convai-widget-core@0.12.4](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.12.4) and [@elevenlabs/convai-widget-embed@0.12.4](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.12.4) - Fixed voice widget transcripts so streamed agent response parts are ignored for voice sessions and late user transcripts are inserted before their matching agent response.
