### ElevenAgents

- **WhatsApp branch and environment overrides**: [Outbound WhatsApp messages](/docs/api-reference/whats-app/outbound-message) and [outbound calls](/docs/api-reference/whats-app/outbound-call) now honor `branch_id` and `environment` passed in `conversation_initiation_client_data`. Overrides are validated before anything is sent — an unknown branch or environment is rejected with an error — and persist for the conversation, so a customer's reply resumes on the requested [branch](/docs/eleven-agents/operate/versioning) and [environment](/docs/eleven-agents/integrate/environment-variables). See the [WhatsApp guide](/docs/eleven-agents/whatsapp) for examples.
- **Procedure APIs**: Added eight public, branch-scoped operations for managing [procedures](/docs/eleven-agents/customization/procedures). You can create, list, retrieve and remove procedures; create, retrieve or discard draft changes; and compile procedure drafts into an agent workflow. Procedure creation accepts `name`, `content`, `type` and `trigger`. An empty `trigger` creates a sub-procedure, while an omitted or `null` trigger is derived from the procedure content.
- **Knowledge base crawl jobs**: Added APIs to create, list, inspect and cancel crawl jobs. Create requests require `url` (string) and support crawl depth, page limits, URL patterns, sitemap URLs, folder placement, automatic synchronization and removal of unavailable documents.
- **Bulk knowledge base management**: Added [bulk dependency checks](/docs/api-reference/knowledge-base/dependent-agents-multiple) and [bulk deletion](/docs/api-reference/knowledge-base/bulk-delete) for 1–20 unique document or folder IDs. Dependency checks support pagination and `dependent_type`; deletion returns an independent success or failure for each ID. Setting `force: true` also removes dependencies and recursively deletes non-empty folders.
- **Batch call result export**: Added [Export batch call results](/docs/api-reference/batch-calling/export) to download recipients and conversation results from a terminal batch as CSV.
- **Conversation filters and analysis data**: [List conversations](/docs/api-reference/conversations/list) and [Text search conversation messages](/docs/api-reference/conversations/messages/text-search) add optional `visited_agent_ids` and `visited_agent_branch_ids` array filters, each limited to 50 values. List requests also accept `data_collection_ids` and `evaluation_criteria_ids` to include corresponding results in each conversation summary. Summaries add optional `data_collection_results`, `evaluation_criteria_results` and `tag_ids`.
- **Referenced analysis configuration**: Agent platform settings add the optional, nullable `analysis_items` field, typed as `AgentAnalysisItems`, to attach evaluation and data-collection items by reference. A `null` value indicates that the agent still uses the legacy inline fields; an empty value indicates a migrated agent with no attached items.
- **Procedure dependency metadata**: Procedure references add `trigger` (string) and arrays for `referenced_tool_ids`, `referenced_kb_ids`, `referenced_procedure_ids` and `referenced_dynamic_variables`.
- **WebRTC token response**: [Get WebRTC token](/docs/api-reference/conversations/get-webrtc-token) responses now require `conversation_id` (string) in addition to `token`. This is a breaking schema change for clients that validate or deserialize the response shape.
- **Knowledge base RAG results**: `KnowledgeBaseRagToolResultModel` adds `chunks` (`KnowledgeBaseRagChunkModel[]`) for RAG-result-in-tool-result mode.

### Studio

- **Draft project status**: `ProjectCreationMetaResponseModel.status` adds `draft`. The project creation type now uses the shared `ProjectCreationMetaType` enum with the same existing values.

### Voices

- **Voice accents**: Added `GET /v1/voices/accents` to list the accents available in the shared voice library. Results can be filtered by `language` and `model_id`, and each accent returns its `accent`, `language`, `code` and human-readable `name`. The `accent` value can be passed to the `accent` query parameter on [Get shared voices](/docs/api-reference/voices/voice-library/get-shared) to filter shared voices.

### Workspaces

- **Webhook usage reporting**: `WebhookUsageType` adds `Flows`.

### SDK Releases

#### JavaScript SDK

- [v2.60.0](https://github.com/elevenlabs/elevenlabs-js/releases/tag/v2.60.0) - Added `voices.accents.get` to list voice accents in the shared voice library, along with the ElevenAgents procedure, knowledge base crawl job and bulk management APIs and the referenced analysis configuration from the latest schema.

#### Python SDK

- [v2.60.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.60.0) - Added the voice accents, ElevenAgents procedure, knowledge base crawl job and bulk management APIs from the latest schema. Also fixed `AsyncConversation` startup so it no longer blocks, and corrected list-of-primitive multipart fields to be sent as repeated form fields.

#### Packages

- [@elevenlabs/client@1.15.2](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.15.2) - Fixed `onAudioAlignment` on WebRTC transports by forwarding alignment metadata from audio messages while leaving audio playback on the LiveKit track.
- [@elevenlabs/react@1.10.2](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact%401.10.2), [@elevenlabs/react-native@1.2.16](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact-native%401.2.16), [@elevenlabs/convai-widget-core@0.14.12](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.14.12) and [@elevenlabs/convai-widget-embed@0.14.12](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.14.12) - Updated dependencies to include the WebRTC alignment fix from `@elevenlabs/client@1.15.2`.
