### ElevenAgents

- **Phone keypad input**: Agent conversation configuration now supports optional `dtmf_input_settings` for [DTMF input](/guides/elevenagents-customization-multimodal-input#dtmf-input). Configure the digit timeout, use `#` as a terminator and redact keypad entries from transcripts, logs and analysis.
- **Conversation attachment history**: [Get conversation](/guides/changelog-api-reference-conversations-get) transcript entries now include `file_inputs`, an array containing every attached file's ID, name, MIME type and URL.
- **Agent tag filtering**: [List agents](/guides/changelog-api-reference-agents-list) now accepts an optional `tags` query parameter. Repeat the parameter to match agents with any of the supplied tags.
- **Batch campaign context**: [Get conversation](/guides/changelog-api-reference-conversations-get) now identifies batch calls with nullable `campaign` metadata containing the required `campaign_id` and `campaign_lead_id`.

### Music

- **Waveform visual data**: [Generate music detailed](/guides/changelog-api-reference-music-compose-detailed), [Stream music with details](/guides/changelog-api-reference-music-compose-detailed-stream) and [Upload music](/guides/changelog-api-reference-music-upload) now accept optional `with_waveform_visual` (boolean, default `false`). Opted-in responses return a low-resolution `waveform_visual` integer array with four samples per second.

### Dubbing

- **Project pagination behavior**: [List Dubbing projects](/guides/changelog-api-reference-dubbing-list-projects) and [List language targets](/guides/changelog-api-reference-dubbing-language-targets-list-language-targets) now clamp `page_size` to 1–100. Project status filtering includes `queued`, and both endpoints document using `next_cursor` to retrieve the next page.

### SDK releases

#### JavaScript SDK

- [v2.66.0](https://github.com/elevenlabs/elevenlabs-js/releases/tag/v2.66.0) - Added `fileIds` to `sendMultimodalMessage`, allowing one message to include multiple file attachments.

#### Python SDK

- [v2.66.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.66.0) - Added `file_ids` to `send_multimodal_message`, allowing one message to include multiple file attachments.

#### Android SDK

- [v0.12.2](https://github.com/elevenlabs/elevenlabs-android/releases/tag/v0.12.2) - Preserved the `onUnhandledClientToolCall` callback when wiring session events. Unhandled client tool calls that expect a response now receive the automatic error response instead of remaining unresolved.

#### ElevenLabs CLI

- [v1.1.0](https://github.com/elevenlabs/cli/releases/tag/v1.1.0) - Regenerated API command bindings and added command-scoped request attribution for ElevenAgents workflows. These commands append `cmd/<command>` to the CLI `User-Agent`, allowing requests from workflows such as `agents push` and `agents create` to be distinguished.

#### Packages

- [@elevenlabs/client@1.23.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.23.0), [@elevenlabs/react@1.15.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact%401.15.0), [@elevenlabs/types@0.22.1](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Ftypes%400.22.1), [@elevenlabs/react-native@1.2.25](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact-native%401.2.25), [@elevenlabs/convai-widget-core@0.17.1](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.17.1) and [@elevenlabs/convai-widget-embed@0.17.1](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.17.1) - Added `fileIds` to `sendMultimodalMessage`. The client sends both `file` and `files` fields for compatibility, and React exposes the updated client API.
