### 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. Fixed Speech Engine JWT verification for API keys with data residency suffixes. Added `phoneNumbers.listV2` and Flows template methods to list and get templates and list, create and get runs. Regenerated clients and types for GPT Image 2.5, Slack agent alerting, parallel tool calls, `gpt-6-astra`, service account API key concurrency limits, Music zero retention, conversation filters and MCP tool approval statuses.

#### Python SDK

- [v2.69.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.69.0) - Added `transcript_edit` to the realtime Speech to Text wrapper, with edited text delivered through `edited_transcript` events. Fixed Speech Engine JWT verification for API keys with data residency suffixes, and made `play` raise an error when `ffplay` fails. Added `phone_numbers.list_v2` and Flows template methods to list and get templates and list, create and get runs. Regenerated clients and types for GPT Image 2.5, Slack agent alerting, parallel tool calls, `gpt-6-astra`, service account API key concurrency limits, Music zero retention, conversation filters and MCP tool approval statuses.

#### ElevenLabs CLI

- [v1.3.2](https://github.com/elevenlabs/cli/releases/tag/v1.3.2) - Added optional `--intent` metadata to collect feedback on CLI usage. Added `elevenlabs feedback missing-capability` to report workflows that the CLI does not support.

## New endpoints

### ElevenAgents

- [List phone numbers page](/guides/changelog-api-reference-phone-numbers-list-v-2) - `GET /v1/convai/v2/phone-numbers`
  - Added optional `page_size` (integer, 1–1,000, default `100`) and `cursor` (nullable string) pagination parameters.
  - Added optional `search`, `label`, `phone_number`, `provider`, `supports_outbound`, `agent_id`, `branch_id`, `sort_by` and `sort_direction` filters. `sort_by` accepts `label` or `phone_number`; `sort_direction` defaults to `asc`.
  - The response contains required `phone_numbers` (array), optional nullable `next_cursor` (string) and `has_more` (boolean, default `false`).

## Updated endpoints

### ElevenAgents

- [Create agent](https://elevenlabs.io/docs/api-reference/agents/create), [Get agent](https://elevenlabs.io/docs/api-reference/agents/get) and [Update agent](https://elevenlabs.io/docs/api-reference/agents/update)
  - Prompt configuration adds `enable_parallel_tool_calls` (boolean, default `true`). Workflow overrides accept a nullable boolean.
  - The `LLM` enum adds `gpt-6-astra`, including conversation initiation overrides.
  - Alerting integration notifiers now use `integration_type` to select `pagerduty` or `slack`. Slack notifiers require `connection_id` and `channel_id` (strings); `channel_id` accepts 1–64 characters.
- [List conversations](/guides/changelog-api-reference-conversations-list) and [Resolve conversation reference](https://elevenlabs.io/docs/api-reference/conversations/resolve)
  - `data_collection_params` no longer accepts the `missing` operator. Use an empty value to match conversations where the field was not collected.
  - An empty value in `dynamic_variable_params` matches conversations where the variable was not set.
- [Create Speech Engine](/guides/changelog-api-reference-speech-engine-create), [Get Speech Engine](/guides/changelog-api-reference-speech-engine-get) and [Update Speech Engine](/guides/changelog-api-reference-speech-engine-update)
  - Added `cascade_timeout_seconds` (number, 2–15). Create requests default to `4`, update requests accept a nullable value and responses require the field.

### Image and video

- [Create image generation](/guides/changelog-api-reference-flows-image-create) - `POST /v1/flows/image`
  - Added request variants for `gpt-image-2.5-flare` and `gpt-image-2.5-sunburst`.
  - Both variants require `prompt` and `model_id`, accept up to 10 `images`, and add `resolution` (`1K`, `2K` or `4K`, default `1K`).
  - `quality` accepts `low`, `medium`, `high`, `xhigh` or `max` and defaults to `high`. `aspect_ratio` accepts `auto` and 14 fixed ratios and defaults to `16:9`.

### Dubbing

- [Create dubbing project](/guides/changelog-api-reference-dubbing-create-project) - `POST /v1/dubbing/project`
  - Multipart `keyterms` accepts repeated fields or a single JSON array.
  - Multipart `webhook_ids` accepts repeated fields, a single JSON array or a comma-separated string.
- [Get workspace resource](/guides/changelog-api-reference-workspace-resources-get), [Share workspace resource](/guides/changelog-api-reference-workspace-resources-share) and [Unshare workspace resource](/guides/changelog-api-reference-workspace-resources-unshare)
  - `WorkspaceResourceType` adds `dubbing_project`.

### Knowledge base

- [Create crawl job](/guides/changelog-api-reference-knowledge-base-create-crawl-job) - `POST /v1/convai/knowledge-base/crawl`
  - Deprecated `max_depth` (integer, default `3`). The field is now a no-op and no longer has minimum or maximum constraints.
  - Crawl job metadata no longer requires `max_depth`.

### User

- [Get user](/guides/changelog-api-reference-user-get) and [Get subscription](/guides/changelog-api-reference-user-subscription-get)
  - Currency enums add `gbp`.
