# Changelog

## September 23, 2026

### Image & Video

- **Sora 2 and Sora 2 Pro retired**: OpenAI is discontinuing the Sora API on September 24, 2026. Both models have been removed from the Image & Video model picker and stop generating on that date. Existing generations remain available in your history. Flows and templates that use a Sora node need to be switched to another video model, such as [Gemini Omni 1.1 Flash](/guides/overview-capabilities-image-video), before they can run again.
- **Seedance 1.5 Pro deprecated**: ByteDance retires Seedance 1.5 Pro on November 11, 2026. The model is no longer offered for new generations and will stop working on that date. Use a [Seedance 2.0 model](/guides/overview-capabilities-image-video) instead.

## September 21, 2026

### ElevenAgents

- **Parallel tool calls**: Agent prompt configuration now includes `enable_parallel_tool_calls` (boolean, default `true`). When enabled, supported models can execute multiple tools in one turn.
- **Agent models**: Added `gpt-6-astra` to the agent LLM options.
- **Alerting**: Agent alerting now supports Slack channels alongside PagerDuty and webhook notifiers.
- **Phone number search**: Added a cursor-paginated phone number endpoint with filters for provider, outbound support, assigned agent and branch, label and phone number.

### Image and video

- **GPT Image 2.5 models**: [Image generation](/guides/changelog-api-reference-flows-image-create) now supports `gpt-image-2.5-flare` and `gpt-image-2.5-sunburst`. Both models accept up to 10 reference images, quality levels through `max`, 14 fixed aspect ratios plus `auto`, and 1K, 2K or 4K output.

### Speech Engine

- **Cascade timeout**: Speech Engine create and update requests now accept `cascade_timeout_seconds` (number, 2–15, default `4`) to control how long ElevenLabs waits for an upstream speech engine before retrying.

### Text to Speech

- **Multi-context turn boundaries**: The `is_final_audio_for_turn` marker is now emitted after every buffered byte for that turn, including MP3 and Opus output. Clients can use the marker as an exact turn boundary without switching to PCM.

### SDK releases

#### JavaScript SDK

- [v2.69.0](https://github.com/elevenlabs/elevenlabs-js/releases/tag/v2.69.0) - Added `transcriptEdit` to the realtime Speech to Text wrapper, with edited text delivered through `edited_transcript` events.

### ElevenLabs CLI

The [ElevenLabs CLI v1.0.0](https://github.com/elevenlabs/cli/releases/tag/v1.0.0) is now available. Every ElevenLabs API operation is available as a subcommand, with JSON, table, YAML and CSV output, automatic pagination and shell completion.

The CLI also provides local configuration workflows for ElevenAgents. Store agent, tool and test configurations as files, synchronize them with push and pull commands, manage branches, run tests, install ElevenLabs UI components and select a data residency region.

::::card-grid
:::card{title="CLI documentation" href="/guides/elevenagents-operate-cli"}
Install the CLI, authenticate and manage agents as code.

### Procedures

Procedures are now generally available in ElevenAgents. A procedure contains task-specific instructions and a trigger that determines when they apply. During a conversation, the agent loads the relevant procedure, allowing one agent to handle distinct tasks without placing every instruction in its system prompt.

Use free-form procedures when the agent can adapt the wording or order of instructions. Use structured procedures when steps must run in a defined order. Both types can be used alongside workflows on the same agent.

### ElevenAgents

- **Conversation triage tickets**: Added APIs for creating tickets about agent performance, creating manual follow-up tickets, listing tickets, assigning workspace members, updating status and assignee, and adding ticket-level or turn-level comments.
- **Conversation observability**: Realtime clients can receive a `context_usage` event after each completed agent turn. The event reports the model, prompt token count and model context limit.

### SDK Releases

#### JavaScript SDK

- [v2.65.0](https://github.com/elevenlabs/elevenlabs-js/releases/tag/v2.65.0) - Added clients and types for conversation triage tickets and lightweight conversation summaries. Conversation APIs add procedure, invalid-tool-call and sort filters; procedure APIs add agent version selection; topic APIs add evaluation detail controls and frustration sorting. The release also adds knowledge base refresh frequency, test environment and alerting integration fields, plus realtime Dubbing message types.

#### Python SDK

- [v2.65.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.65.0) - Added clients and types for conversation triage tickets and lightweight conversation summaries. Conversation APIs add procedure, invalid-tool-call and sort filters; procedure APIs add agent version selection; topic APIs add evaluation detail controls and frustration sorting. The release also adds knowledge base refresh frequency, test environment and alerting integration fields, and preserves repeated multipart fields for Speech to Text `keyterms` and Dubbing `webhook_ids`.

#### Swift SDK

- [v3.3.0](https://github.com/elevenlabs/elevenlabs-swift-sdk/releases/tag/v3.3.0) - Added typed client error parsing, `expects_response` handling and type-safe tool results. WebRTC startup now becomes ready when the agent joins instead of waiting for audio-track subscription. The release also hardens URL handling, suppresses unknown-event noise and removes realtime-thread allocation from software mute processing.

#### Packages

- [@elevenlabs/client@1.19.1](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.19.1), [@elevenlabs/react@1.12.3](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact%401.12.3), [@elevenlabs/react-native@1.2.21](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact-native%401.2.21), [@elevenlabs/convai-widget-core@0.16.2](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.16.2) and [@elevenlabs/convai-widget-embed@0.16.2](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.16.2) - WebRTC output capture now uses self-hosted AudioWorklet paths under strict content security policies. Worklet caching includes the requested source, preventing an earlier inline URL from replacing a self-hosted path. React Native setup errors now point to `@elevenlabs/react-native`.
- [@elevenlabs/client@1.20.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.20.0), [@elevenlabs/react@1.12.4](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact%401.12.4), [@elevenlabs/react-native@1.2.22](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact-native%401.2.22), [@elevenlabs/convai-widget-core@0.16.3](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.16.3) and [@elevenlabs/convai-widget-embed@0.16.3](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.16.3) - Added optional `webRtc.iceTransportPolicy`. Set it to `relay` to restrict WebRTC ICE candidates to TURN relays on networks that block direct UDP traffic.
- [@elevenlabs/client@1.21.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.21.0), [@elevenlabs/react@1.13.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact%401.13.0), [@elevenlabs/types@0.21.1](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Ftypes%400.21.1), [@elevenlabs/react-native@1.2.23](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact-native%401.2.23), [@elevenlabs/convai-widget-core@0.16.4](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.16.4) and [@elevenlabs/convai-widget-embed@0.16.4](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.16.4) - Added the `onContextUsage` callback and `ContextUsageEvent` type. React exposes the callback through `useConversation`. React Native now resolves through its package export condition instead of browser-global detection.
- [@elevenlabs/client@1.22.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.22.0), [@elevenlabs/react@1.14.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact%401.14.0), [@elevenlabs/types@0.22.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Ftypes%400.22.0), [@elevenlabs/react-native@1.2.24](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact-native%401.2.24), [@elevenlabs/convai-widget-core@0.17.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.17.0) and [@elevenlabs/convai-widget-embed@0.17.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-embed%400.17.0) - Added first-message rich content with attributed button responses, `onExternalAgentDisconnected` and `onMCPToolApprovalRequest`. WebRTC now uses the selected input device, preserves mute state when switching microphones and fails setup if initiation data cannot be sent. The widget adds concurrency queue status, optional language selection on the collapsed trigger and first-message rendering for agents that support both text and voice.

## Updated Endpoints

### ElevenAgents

- [Get signed URL](/guides/changelog-api-reference-conversations-get-signed-url) - `GET /v1/convai/conversation/get-signed-url`
  - Added optional `debug_events_request` (boolean, default `false`). Debug events require editor access to the agent.
- [Get WebRTC token](/guides/changelog-api-reference-conversations-get-webrtc-token) - `GET /v1/convai/conversation/token`
  - Added optional `debug_events_request` (boolean, default `false`). The legacy `GET /v1/convai/conversation/get_signed_url` route accepts the same parameter.
- [List conversations](/guides/changelog-api-reference-conversations-list) - `GET /v1/convai/conversations`
  - Added optional `triggered_procedure_ids` (nullable string array, maximum 50) to match conversations where any specified procedure ran.
  - Added optional `include_invalid_tool_calls` (boolean, default `false`) to include tool calls that did not run.
  - Added optional `sort_direction` (`asc` or `desc`, default `desc`) for call start time.
- [Text search conversation messages](/guides/changelog-api-reference-conversations-messages-text-search) - `GET /v1/convai/conversations/messages/text-search`
  - Added optional `triggered_procedure_ids` (nullable string array, maximum 50).

  - Topic responses add nullable `success_rate` (number), while the overall response adds `aggregated_run_count` (integer, default `0`).
  - `from_unix_secs` is floored to the start of its UTC day. A bounded range aggregates completed daily discovery runs; omitting both bounds returns the latest run.
- [List procedures](/guides/changelog-api-reference-agents-procedures-list) (`GET /v1/convai/agents/{agent_id}/branches/{branch_id}/procedures`) and [Get procedure](/guides/changelog-api-reference-agents-procedures-get) (`GET /v1/convai/agents/{agent_id}/branches/{branch_id}/procedures/{procedure_id}`)
  - Added optional nullable `agent_version_id` (string) to retrieve procedures from a specific agent version.
- [Create test](/guides/changelog-api-reference-tests-create) and [Update test](https://elevenlabs.io/docs/api-reference/tests/update)
  - Added optional nullable `environment` (string) to response, simulation and tool-call unit test schemas. The value selects environment-specific URLs, headers and auth connections; it defaults to `production`.
- [Create URL document](/guides/changelog-api-reference-knowledge-base-create-from-url), [Create crawl job](/guides/changelog-api-reference-knowledge-base-create-crawl-job) and [Create folder](/guides/changelog-api-reference-knowledge-base-create-folder)
  - Added optional nullable `minimum_frequency_days` (integer, 1–180) for auto-sync. The default is `7`, and a stricter parent-folder frequency takes precedence.

### Music

- [List Music Finetunes](/guides/changelog-api-reference-music-finetunes-list) - `GET /v1/music/finetunes`
  - Increased the maximum `page_size` from 100 to 150. The default remains 50.

## Schema Changes

### ElevenAgents

- Agent update requests add optional nullable `procedures` (`object<string, ProcedureVersionRef>`). Each value requires `procedure_id` and `version_id` (strings). An empty object removes all procedures.
- Conversation initiation configuration adds `enable_procedure_ids_from_client` (boolean, default `false`). Initiation data adds optional nullable `procedure_ids` (string array); an empty array disables all procedures for the starting agent.
- `ClientEvent` adds `context_usage`.
- Soft-timeout overrides add optional nullable `additional_soft_timeout_messages` (string array).
- Constant values in analysis and schema override models now accept `null`.
- Widget configuration defaults for `mic_muting_enabled` and `transcript_enabled` changed from `false` to `true`. Set them explicitly to `false` to preserve the previous behavior.

### Workspace

- [Get user](/guides/changelog-api-reference-user-get) responses removed `xi_api_key` from `UserResponseModel`.
- `ResourceMetadataResponseModel.role_to_group_ids` now accepts custom role IDs as keys instead of restricting keys to `admin`, `editor`, `commenter` and `viewer`.
- Direct publishing responses add optional nullable `restricted_to_user_email_domains` (string array).
- Pending subscription switch responses add `go` to `next_tier`.

### MCP server

- **Local MCP server deprecated**: The local [ElevenLabs MCP server](https://github.com/elevenlabs/elevenlabs-mcp) and [MCP player](https://github.com/elevenlabs/elevenlabs-mcp-player) are deprecated in favor of the [hosted MCP server](/guides/elevenagents-operate-hosted-mcp). Both repositories are archived and will no longer receive updates. The hosted server is available at `https://api.elevenlabs.io/v1/mcp`, signs in with your ElevenLabs account through OAuth and requires no local installation or API key. See the [hosted MCP server documentation](/guides/elevenagents-operate-hosted-mcp) for setup instructions for Claude, Cursor and other MCP clients.

## August 17, 2026

### ElevenCreative

- **Image, video and speech generation APIs**: New asynchronous Flows APIs create, list and retrieve video, image and speech generations. Generation responses expose `pending`, `generating`, `completed` and `failed` states, and requests can include a webhook target for completion events.
- **Reusable media assets**: New asset APIs upload, list, retrieve and delete workspace media. Image, video and audio references can use an uploaded asset, a previous generation or inline base64 data, allowing generation jobs to be chained. See [References and assets](/guides/elevenapi-guides-how-to-image-and-video-references).

### ElevenAgents

- **Lightweight conversation summaries**: [Get conversation summary](/guides/changelog-api-reference-conversations-get-summary) returns the generated title, transcript summary, call outcome and plain user or agent messages without loading the full transcript. The optional `max_messages` query parameter is an integer from 1 to 200 (default `40`); longer conversations set `messages_omitted` to `true`. Useful for agents that need to preserve context.
- **Conversation topic pagination and sorting**: [Get agent conversation topics](/guides/changelog-api-reference-conversations-topics-get) adds optional cursor pagination and sorting. Use `page_size` (integer, 1–100), `cursor` (string), `sort_by` (`conversations`, `sentiment` or `success_rate`) and `sort_direction` (`asc` or `desc`). Responses add `has_more` and nullable `next_cursor`.
- **Concurrency wait queues**: Agent platform settings add optional `queueing` (`AgentQueueingConfig`). Set `enabled` to `true` to hold callers when the agent reaches its concurrency limit; `wait_timeout_seconds` is an integer up to 1,800 (default `180`).
- **Turn and workflow controls**: Turn configuration adds `merge_with_default_ignore_terms` (boolean, default `false`) to combine custom interruption terms with curated defaults. Soft timeouts add `disable_until_first_user_message` (boolean, default `false`), and workflow tool locators add optional `schema_overrides` for per-node parameter overrides.
- **Background audio defaults**: `BackgroundSoundConfig.volume` now defaults to `0.15` instead of `0.6`, and `crossfade_loop` now defaults to `true` instead of `false`. Set these fields explicitly to retain the previous behavior.

### SDK Releases

#### JavaScript SDK

- [v2.64.0](https://github.com/elevenlabs/elevenlabs-js/releases/tag/v2.64.0) - Added `client.assets` for uploading, listing, retrieving and deleting assets, plus `client.flows` for asynchronous video, image and speech generation. Turn configuration adds `mergeWithDefaultIgnoreTerms`. Removed `CustomToolApiSchemaConfig` and `scimExternalId` from `WorkspaceGroupResponseModel`.

#### Python SDK

- [v2.64.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.64.0) - Added assets and Flows clients for asynchronous video, image and speech generation, plus `merge_with_default_ignore_terms` in turn configuration. On-prem session setup adds `extra_setup_config` for passing additional setup-message fields.

#### Packages

Scribe audio worklets can now be self-hosted for strict content security policies. Disconnect handling now reaches `disconnected` consistently and prevents late callbacks from clearing a newer session. The widget renders quick replies and links inline, restores Markdown in voice transcripts and fixes language menu positioning inside container-query layouts.
- [@elevenlabs/client@1.19.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.19.0), [@elevenlabs/react@1.12.2](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact%401.12.2), [@elevenlabs/types@0.21.0](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Ftypes%400.21.0), [@elevenlabs/react-native@1.2.20](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Freact-native%401.2.20) and [@elevenlabs/convai-widget-core@0.16.1](https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fconvai-widget-core%400.16.1) - Added realtime Speech to Text options for secondary languages, entity detection and background audio filtering. Added final transcript, detected entity and invalid request events; aligned timestamp word types with the live schema; and fixed microphone permission failures preventing `useScribe` reconnection.

### Dubbing v2 API

Dubbing v2 is now available through the API. It translates audio and video into more than 90 languages while preserving each speaker's voice, tone and pacing.

The new project-based API keeps source transcripts and translations as editable JSON. Create a project from a file or URL, add one or more target languages, edit individual transcript segments or translations, then regenerate only the regions that changed. Follow the [Dubbing quickstart](/guides/elevenapi-guides-cookbooks-dubbing) to create your first dub.

:::

## August 3, 2026

### 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](/guides/changelog-api-reference-conversations-list) and [Text search conversation messages](/guides/changelog-api-reference-conversations-messages-text-search) 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](/guides/elevenapi-guides-how-to-speech-to-text-batch-entity-detection) 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

## July 27, 2026

### ElevenAgents

- **WhatsApp branch and environment overrides**: [Outbound WhatsApp messages](/guides/changelog-api-reference-integrations-whats-app-outbound-message) and [outbound calls](/guides/changelog-api-reference-integrations-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](/guides/elevenagents-operate-versioning) and [environment](/guides/elevenagents-integrate-environment-variables). See the [WhatsApp guide](/guides/elevenagents-whatsapp) for examples.
- **Procedure APIs**: Added eight public, branch-scoped operations for managing [procedures](/guides/elevenagents-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](/guides/changelog-api-reference-knowledge-base-dependent-agents-multiple) and [bulk deletion](/guides/changelog-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](/guides/changelog-api-reference-batch-calling-export) to download recipients and conversation results from a terminal batch as CSV.
- **Conversation filters and analysis data**: [List conversations](/guides/changelog-api-reference-conversations-list) and [Text search conversation messages](/guides/changelog-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](/guides/changelog-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](/guides/changelog-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.

### Music

- **Music Finetunes API**: Added API support for managing [Music Finetunes](/guides/elevencreative-products-music-finetunes). Five endpoints let you create a Finetune from uploaded audio, list accessible Finetunes, retrieve training status, update metadata and visibility, or delete a Finetune. All music generation SDK methods now expose `finetune_id`.

### ElevenAgents

- **Resolve external conversation references**: Added `GET /v1/convai/conversations/resolve` to resolve a Slack message URL or Zendesk ticket URL to a conversation. Requests require `agent_id` and `reference` query parameters (strings).
- **Query agent knowledge bases**: Added `POST /v1/convai/agents/{agent_id}/knowledge-base/rag-query` for read-only RAG queries against an agent's knowledge base. The request requires `query` (string), accepts optional `branch_id` (string), and returns ranked chunks with document, chunk, text and vector-distance metadata. This endpoint is excluded from generated SDKs.
- **Knowledge base content formats**: Knowledge base file, text and URL responses add optional `content_format` (`html` | `markdown`, default `html`).
- **Agent voice configuration**: TTS override schemas add optional client-overridable `model_id` (`TTSConversationalModel`). The default for `enable_phoneme_tags` changes from `false` to `true`.
- **Faster backup LLM cascade**: The default `cascade_timeout_seconds` changes from 8 to 4 seconds. The allowed range remains 2–15 seconds.
- **Tool parameter value sources**: Object tool parameters can now use `dynamic_variable`, `constant_value` or `is_omitted`, matching existing scalar and array controls. Constant schema overrides now accept arbitrary arrays and objects.
- **Full-response guardrails**: Custom guardrails add optional `evaluate_full_response_only` (boolean, default `false`) to evaluate the complete non-TTS response once. This option requires blocking mode.

## June 22, 2026

### ElevenAgents

- **Branch rebase**: Added `POST /v1/convai/agents/{agent_id}/branches/{branch_id}/rebase` to rebase a branch onto the latest main while preserving branch-specific changes. Agent version parent models add optional `rebased_from_version_id` (string) to track the source version after a rebase.
- **Conversation product filtering**: [List conversations](/guides/changelog-api-reference-conversations-list) and [Text search conversation messages](/guides/changelog-api-reference-conversations-messages-text-search) add optional `conversation_product_type` query parameter (`agents` | `speech_engine`) to filter results by product. Conversation models introduce `ConversationProduct` for this distinction.
- **Conversation termination filtering**: [List conversations](/guides/changelog-api-reference-conversations-list) adds optional `termination_reasons` query parameter (array of strings) to filter conversations by how they ended.
- **Per-agent topic discovery**: [Create agent](https://elevenlabs.io/docs/api-reference/agents/create) and [Update agent](https://elevenlabs.io/docs/api-reference/agents/update) platform settings add optional `topic_discovery` (`TopicDiscoverySettings`) for per-agent topic discovery configuration.
- **Background sound configuration**: Agent platform and conversation configuration models add optional `background_sound` (`BackgroundSoundConfig`) for ambient audio during conversations.
- **Turn interruption ignore terms**: Turn configuration schemas add optional `interruption_ignore_terms` (array of strings) to suppress turn detection on specific phrases.
- **Soft timeout filler randomization**: Soft timeout configuration adds optional `randomize_fillers` (boolean) to shuffle filler messages across soft timeouts. Soft timeout message and LLM prompt override fields now support dynamic variables.
- **Transcript user identifiers**: Transcript message models add optional `user_identifier` (string) on user-authored messages.
- **Simulation success conditions**: Agent simulation test schemas add optional `success_conditions` (array, up to 30 items). The legacy `success_condition` field is deprecated in favor of the array form.
- **Agent test repeat limit**: [Run tests on the agent](https://elevenlabs.io/docs/api-reference/tests/run-tests) raises the maximum `repeat_count` from 20 to 50.
- **Tool schema dynamic allowed values**: ElevenAgents tool JSON schema properties add optional `allowed_values_dynamic_variable` (string) for server-verified LLM value picks sourced from dynamic variables.
- **Widget signed URL docs**: [Get widget](/guides/changelog-api-reference-widget-get) updates `conversation_signature` documentation to reference `/v1/convai/conversation/get_signed_url`.

### Introducing Music v2

Music v2 is now available via the ElevenLabs API. Set `model_id` to `music_v2` on [Generate music](/guides/changelog-api-reference-music-compose), [Stream music](/guides/changelog-api-reference-music-stream), [Generate music detailed](/guides/changelog-api-reference-music-compose-detailed) and [Upload music](/guides/changelog-api-reference-music-upload) to use the new model. Music v2 introduces chunk-based composition plans built from `GenerationChunk` and `AudioRefChunk` segments, giving you finer control over structure, pacing and arrangement than the prompt-based `music_v1` flow.

Use `music_v2` composition plans on generation and upload requests, or generate a plan first via the composition-plan endpoint. Request and response bodies accept either v1 or v2 plan shapes, so you can migrate endpoint by endpoint. `MusicPrompt` remains available for `music_v1` only.

- **Soft timeout filler messages**: `SoftTimeoutConfig` and `SoftTimeoutConfigWorkflowOverride` add optional `additional_soft_timeout_messages` (array of strings, up to 7) and `max_soft_timeouts_per_generation` (integer, 1–8, default `1`). The primary `message` applies to the first timeout; subsequent timeouts use the additional messages or a built-in filler.
- **ASR provider default**: The default `ASRConversationalConfig.provider` value changes from `elevenlabs` to `scribe_realtime`. The `elevenlabs` value remains in the enum but is deprecated.
- **Conversation product field**: [Get conversation details](/guides/changelog-api-reference-conversations-get) response adds optional `conversation_product` (string, default `agent`) to identify the product that handled the conversation.
- **Knowledge base external sync**: Knowledge base file and folder response models add optional `external_sync_info` (Google Drive sync metadata via `ExternalFileSyncInfo` / `ExternalFolderSyncInfo`) and optional `is_frozen` (boolean) to indicate whether synced content can be edited.
- **Tool schema omit overrides**: ConvAI tool JSON schema properties add optional `is_omitted` (boolean) and `OmitSchemaOverride` with `source: omit`, allowing fields to be explicitly omitted from tool payloads.
- **Procedure guardrails**: Procedure version schemas add optional `guardrails`.

### Workspaces

- **URL secret auth connections**: Workspace auth connection create, list and response unions add `url_secret` (`UrlSecretAuthResponse`) as a supported auth connection type for tools that fetch secrets from a URL.
- **Agent QA Evaluations webhooks**: `WebhookUsageType` adds `Agent QA Evaluations` as a webhook usage category for agent quality-assurance event delivery.

### Text to Dialogue

- **Zero retention mode**: [Convert text to dialogue](/guides/changelog-api-reference-text-to-dialogue-convert), [Stream text to dialogue](/guides/changelog-api-reference-text-to-dialogue-stream), [Convert text to dialogue with timestamps](/guides/changelog-api-reference-text-to-dialogue-convert-with-timestamps) and [Stream text to dialogue with timestamps](/guides/changelog-api-reference-text-to-dialogue-stream-with-timestamps) add optional `enable_logging` query parameter (boolean, default `true`). Set `enable_logging=false` to use zero retention mode with no history or request stitching. Zero retention mode is available to enterprise customers only.

### ElevenCreative Studio

- **Safesearch adult metadata**: [Get project](/guides/api-reference-studio-get-project) `publishing_read` responses add optional `safesearch_adult` (nullable boolean) on `DirectPublishingReadResponseModel` for direct publishing content classification.

## June 1, 2026

### ElevenAgents

- **Exotel telephony integration**: Added Exotel as a first-class telephony provider alongside Twilio and SIP trunking. New [Exotel outbound call](/guides/changelog-api-reference-integrations-exotel-outbound-call) endpoint (`POST /v1/convai/exotel/outbound-call`) initiates outbound calls via the Exotel Connect API with `agent_id`, `agent_phone_number_id`, `to_number`, optional `conversation_initiation_client_data` and optional `telephony_call_config`. Exotel phone number create, list, get and update schemas are available, and `exotel` is added to `TelephonyProvider`, conversation initiation source and transfer result enums.
- **Workflow-aware agent transfers**: `AgentTransfer` now allows a nullable `agent_id` so transfers can stay on the current agent, adds optional `node_id` to start at a specific node in the destination workflow, and only requires `condition`. Successful `transfer_to_agent` tool results can include nullable `to_node`, aligning transfers with workflow-node targets.
- **Agent test repeat runs**: [Run tests on the agent](https://elevenlabs.io/docs/api-reference/tests/run-tests) accepts optional `repeat_count` (integer, 1–20, default `1`) to run each test multiple times. When `repeat_count` is greater than 1, responses include `bucketing_status` and `result_groups` for grouped summaries. Unit test create, update and summary schemas add optional `conversation_initiation_source` so tests can simulate a specific channel.
- **Conversation filtering**: [List conversations](/guides/changelog-api-reference-conversations-list) adds optional `workflow_node_entered_id` (string) to filter conversations that entered a given workflow node. [Text search conversation messages](/guides/changelog-api-reference-conversations-messages-text-search) adds optional `topic_ids` (array of strings) to filter by topic IDs assigned during topic discovery.
- **Agent versioning query parameters deprecated**: `enable_versioning` on [create agent](https://elevenlabs.io/docs/api-reference/agents/create) and `enable_versioning_if_not_enabled` on [update agent](https://elevenlabs.io/docs/api-reference/agents/update) are marked deprecated. All agents are versioned and these parameters are ignored.
- **Procedure compiler mode**: Removed `append` from `ProcedureCompilerMode`.

### Workspaces

- **Revoke API key**: Added [revoke API key](https://elevenlabs.io/docs/api-reference/api-keys/revoke) endpoint (`DELETE /v1/workspaces/api-keys/revoke`) with required `api_key_name` query parameter to revoke a workspace API key by name. This endpoint is destructive and requires additional account permissions, even though the documentation is public. Contact your ElevenLabs representative to enable it for your account.
- **Resource access disclosure**: Resource access response models add optional `access_source` (`creator`, `explicit`, `workspace_default`, `workspace_admin`) so clients can disclose why a user has access to a shared resource.

### Speech to Text

- **Larger upload limit**: [Convert speech to text](/guides/changelog-api-reference-text-to-dialogue-convert) now accepts audio and video files up to 5.0GB, increased from 3.0GB.

### Dubbing

- **hCaptcha support**: [Dub a video or audio file](/guides/changelog-api-reference-legacy-dubbing-create) request body adds optional `hcaptcha_token` (string) for bot protection on dubbing project creation.
- **Zip render format**: `RenderType` adds `zip` alongside existing output formats such as `mp4`, `aac`, `mp3`, `wav`, `aaf`, `tracks_zip` and `clips_zip`.
