### ElevenAgents

- **Users page is now generally available**: The [list users](/guides/changelog-api-reference-users-list) page, which groups conversations by a user identifier, is now available to all workspaces. This allows you to view all users who have interacted with your agents, their conversation history, and contact details in a unified view.

- **SIP inbound headers as dynamic variables**: Custom SIP `X-` headers from inbound SIP trunking calls are now automatically exposed as dynamic variables in ElevenAgents conversations. Any custom SIP header (e.g., `X-Contact-ID`, `X-Campaign-ID`) passed by the caller is available in the agent prompt using `{{sip_contact_id}}`, `{{sip_campaign_id}}`, etc. These variables are also visible in the conversation history under the Phone Call tab. Reserved headers such as `X-Call-ID` and `X-Caller-ID` continue to map to `system__call_sid` and `system__caller_id` and are not overridden.

- **Conversation filtering by tool outcome**: The [list conversations](/guides/changelog-api-reference-conversations-list) and [text search conversations](/guides/changelog-api-reference-conversations-messages-text-search) endpoints now accept `tool_names_successful` and `tool_names_errored` query parameters (array of strings) to filter conversations by which tools succeeded or returned errors during the call.

- **User listing improvements**: The [list users](/guides/changelog-api-reference-users-list) endpoint now supports a `sort_by` query parameter accepting `last_contact_unix_secs` (default) or `conversation_count`, and a `branch_id` query parameter to filter users by agent branch.

- **Force delete tools**: The [delete tool](https://elevenlabs.io/docs/api-reference/tools/delete) endpoint now accepts a `force` query parameter (boolean, default `false`). When set to `true`, the tool is deleted even if it is used by agents, and it is automatically removed from all dependent agents and branches.

- **Conversation embedding retention**: The [ElevenAgents settings](https://elevenlabs.io/docs/api-reference/workspace/get) response now includes `conversation_embedding_retention_days`, which controls how long conversation embeddings are retained (maximum 365 days). A `null` value uses the system default of 30 days.

- **Content threshold guardrail**: Added the `ContentThresholdGuardrail` schema, which provides a configurable threshold-based guardrail with an `is_enabled` flag and a `threshold` value for content moderation.

### Workspaces

- **Get all workspace groups**: New [GET /v1/workspace/groups](https://elevenlabs.io/docs/api-reference/workspace/groups/list) endpoint returns all groups in the workspace, including each group's name, ID, members, permissions, usage limit, and character count.

- **Seat type in bulk workspace invites**: The [invite multiple users](/guides/changelog-api-reference-workspace-invites-create-batch) endpoint now accepts an optional `seat_type` field to specify the seat type (e.g., `workspace_member`, `workspace_admin`) for all invited users in a bulk operation.

- **Mobile SSO reliability improvements**: Fixed a regression where SSO login on mobile would get stuck on "Authenticating..." after a user logged out and attempted to sign in again. Also fixed workspace switching for mobile SSO users who sign in via SAML or OIDC providers.

### Music

- **Section duration control**: The [generate music detailed](/guides/changelog-api-reference-music-compose-detailed) endpoint now supports `respect_sections_durations` (boolean), which controls whether the model adheres to the duration specified for each section in the composition plan.

### ElevenCreative Studio

- **Chapter visual content indicator**: Chapter response models now include a `has_visual_content` boolean field indicating whether the chapter contains visual content.

- **Text shadow and outline styles**: ElevenCreative Studio text styling now supports `text_shadow` and `text_outline` options via the new `StudioTextStyleShadowModel` and `StudioTextStyleOutlineModel` schemas, enabling richer visual text customization within ElevenCreative Studio projects.

- **Media generation clip task type**: The `PendingClipTask.type` enum now includes the `media_generation` value, expanding clip task categorization to cover media generation workflows.
