### ElevenAgents

- **OAuth and advanced authentication for MCP servers**: MCP servers now support workspace auth connections, enabling OAuth2 Client Credentials, Basic Auth, Bearer Auth, JWT, and custom header authentication. Select an auth connection when creating or editing an MCP server to automatically handle token refresh and authentication headers. See the [MCP server documentation](/guides/elevenagents-customization-tools-mcp) for more details.
- **LLM information endpoint**: Added a new endpoint to list available LLMs with deprecation status, capabilities, and context limits. This enables clients to programmatically discover which models are available and which are being deprecated. See [List Available LLMs](https://elevenlabs.io/docs/api-reference/llm/list) for details.
- **Conversation history redaction**: Added support for redacting sensitive information from conversation transcripts, audio, and analysis before being stored. Configure specific entity types to redact (such as names, email addresses, etc.) using the new `conversation_history_redaction` setting in agent privacy configuration. See the [docs page](/guides/elevenagents-customization-privacy-conversation-history-redaction) for more details.
- **Enhanced guardrails**: Introduced two new guardrail types for agents:
  - `focus`: Helps keep conversations on-topic
  - `prompt_injection`: Detects and prevents prompt injection attempts
  - Note: The `alignment` guardrail has been removed
- **Conversation search endpoints**: Added two new endpoints for searching conversation messages:
  - [Text search](/guides/changelog-api-reference-conversations-messages-text-search) - Full-text and fuzzy search over transcript messages
  - [Smart search](/guides/changelog-api-reference-voices-search) - Semantic search using embeddings
- **File uploads in conversations**: Added endpoints to upload and manage files within conversations:
  - [Upload file](https://elevenlabs.io/docs/api-reference/conversations/upload-file) - Upload files to a conversation
  - [Delete file](https://elevenlabs.io/docs/api-reference/conversations/delete-file) - Remove uploaded files
- **New embedding model**: Added support for `qwen3_embedding_4b` embedding model in knowledge base RAG indexing.

### Workspaces

- **Image and video generation permission**: Workspace administrators can now control access to image and video generation features. This new permission allows you to restrict which workspace members can use these capabilities. Configure this in your workspace settings under member permissions.

### Music

- **Workspace sharing**: Songs can now be shared within workspaces. The `songs` resource type has been added to workspace resource sharing endpoints.
