ElevenAgents

• Agent version metadata: Added an API endpoint to retrieve metadata for a specific agent version. The response includes the version ID, agent ID, branch ID, description, sequence number, commit timestamp, parents and access information.
• Conversation filtering: Added a text_only filter to conversation list and message text search endpoints so developers can narrow results to text-only conversations.
• Procedure loading: Added load_procedure as a system tool configuration with ProcedureAtVersion, and added skills to ProcedureCompilerMode. ProcedureSettings.compiler_mode now defaults to skills.
• Agent configuration updates: Added gemini-3.1-flash-lite and qwen35-397b-a17b as LLM options, added genesys_bot_connector as a conversation initiation source, added auto_resolve_after_inactive_minutes to alerting settings, and added attributes_to_headers to SIP trunk configuration.
• Custom LLM temperature: Agent prompt temperature can now be set to null to omit the temperature field from downstream LLM requests.

Workspaces

• Auth connection updates: Added an API endpoint to update workspace auth connections. The endpoint supports updating basic auth, OAuth2 client credentials and OAuth2 JWT connections. OAuth2 client credentials now support custom_headers for token requests.
• Auth connection types: Added bearer auth create request support and Slack bot auth response schemas.
• Workspace resource types: Added convai_templates and transcription_tasks to workspace resource types.

Voice Isolator

• Video processing status: Audio isolation history items now include the video_processing_failed boolean field.
