ElevenAgents

Section titled “ElevenAgents”
  • SIP logs: SIP signaling logs are now available for SIP trunk calls in conversation history and phone number settings. Logs include the SIP call ID, phone numbers, addresses, transport, message direction, raw messages and errors to help debug call setup and routing issues.
  • Knowledge base document updates: New API to list indexed (RAG) chunks for a document. Documents can also be edited in place: rename the item and, for text-based documents, update the body without re-uploading the file. (File-based documents still use the existing replace-file flow where applicable.)
  • SMS conversation metadata: Added SMS support to conversation metadata with SMSConversationInfo, sms as an authorization method and twilio_sms as a conversation initiation source.
  • Agent configuration updates: Added background music configuration schemas, alerting monitor configuration, 2D layout fields, widget file upload configuration, and new LLM options gpt-5.4-mini, gpt-5.4-nano, gpt-5.4-mini-2026-03-17 and gpt-5.4-nano-2026-03-17.

Workspaces

Section titled “Workspaces”
  • API request analytics: Added a workspace analytics endpoint for querying API requests with time range, filtering, search, sort and limit controls.
  • API key IP allowlisting: Added allowed_ips to service account API key create, edit and response schemas. Create requests accept an array of IP addresses or CIDR ranges, or null to allow all IPs. Edit requests also accept clear and no_update.
  • Workspace permissions: Added conversational_ai_read and voice_design to workspace group permissions.

Voice Design

Section titled “Voice Design”
  • Voice preview migration: Deprecated POST /v1/text-to-voice/create-previews. Use Design a voice to create previews, then use the returned generated_voice_id when creating a voice.

Voice Changer

Section titled “Voice Changer”
  • WAV output formats: Added wav_8000, wav_16000, wav_22050, wav_24000, wav_32000, wav_44100 and wav_48000 to the output_format query parameter on speech-to-speech conversion.
