### 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`.

### Music

- **Higher-quality output formats**: [Generate music](/guides/changelog-api-reference-music-compose), [Generate music detailed](/guides/changelog-api-reference-music-compose-detailed) and [Stream music](/guides/changelog-api-reference-music-stream) add `mp3_48000_240` and `mp3_48000_320` to supported `output_format` values. When `output_format` is `auto`, v2 models now default to `mp3_48000_192` instead of `mp3_48000_128`.
- **Section duration flag clarification**: `respect_sections_durations` applies only with `composition_plan` on `music_v1`. On `music_v2`, section durations are always enforced and this flag is ignored.
- **Composition plan schema split**: Music request `composition_plan` uses a `oneOf` union of `MusicPrompt` and `CompositionPlan`. The former is used for `music_v1` composition plans and the latter for `music_v2`.

### Dubbing

- **Project list filters**: [List dubs](/guides/changelog-api-reference-legacy-dubbing-list) adds optional `dubbing_statuses`, `dubbing_models`, `target_language_codes` and `creation_sources` array query parameters for filtered listing. The `order_by` parameter now accepts `name` in addition to `created_at`.

### Workspaces

- **Lock and disable reasons**: Workspace and API key models add `LockReason` and optional `disable_reason` fields. Workspace group settings add optional `scim_frozen` (boolean) for SCIM-managed freeze state.

### ElevenCreative Studio

- **Caption animations**: Studio caption enter and exit animation enums add `pop`, `slide_up` and `slide_down`.
