Added `scope` field to `PromptEvaluationCriteria`, `data_collection_scopes` to [agent platform settings](/docs/eleven-agents/customization/agent-analysis), and a new `scoped` array of `ScopedAnalysisResult` on the [conversation analysis](/docs/api-reference/conversations/analysis/run-analysis) response. This is particularly useful for multi-agent workflows where each agent should be evaluated independently. - **Agent test folder management**: Tests can now be organized into folders. New endpoints for [creating](/docs/api-reference/tests/test-folders/create), [retrieving](/docs/api-reference/tests/test-folders/get), [updating](/docs/api-reference/tests/test-folders/update), and [deleting](/docs/api-reference/tests/test-folders/delete) test folders, plus [bulk moving](/docs/api-reference/tests/test-folders/move) tests between folders. - **Tool and knowledge base overrides in workflows**: Agent workflow node overrides now support `tool_ids` and `knowledge_base` fields in `PromptAgentAPIModelOverrideConfig`, allowing workflow nodes to control which tools and knowledge base documents each sub-agent can access. - **Response filter `hide_all` mode**: Added `hide_all` option to `ResponseFilterMode`, forcing the system to hide all fields of a tool response from the agent. - **Visited agents in conversation history**: The [get conversation](/docs/api-reference/conversations/get) response now includes a `visited_agents` array of `VisitedAgentRef` objects (with `agent_id` and `branch_id`), tracking which agents participated in a multi-agent conversation. - **Multimodal message support in hooks**: The `useConversationControls` hook now exposes `sendMultimodalMessage`, and the `MultimodalMessageInput` type is exported from `@elevenlabs/client`, making it easier to send images and other multimodal content during conversations. ### Speech to Text - **Audio duration in responses**: The [convert speech to text](/docs/api-reference/speech-to-text/convert) response now includes an `audio_duration_secs` field, providing the total duration of the transcribed audio without requiring client-side calculation. ### Voices - **Recording quality and review status**: The [get voice](/docs/api-reference/voices/get) response now includes `recording_quality` (enum: `studio`, `good`, `ok`, `poor`, `bad`) and `labelling_status` (enum: `in_review`, `review_complete`) fields, providing visibility into voice quality assessment. ### SDK Releases #### JavaScript SDK - [v2.42.0](https://github.com/elevenlabs/elevenlabs-js/releases/tag/v2.42.0) - Fern regeneration for the April 7, 2026 API schema, including scoped analysis, test folders, and DTMF input support. #### Python SDK -
