Voices Live moderated voices filter: Added include_live_moderated query parameter to the shared voices endpoint, allowing you to include or exclude voices that are live moderated.

Learn more.Skip turn system tool: Introduced a new system tool called skip_turn. When enabled, the agent will skip its turn if the user explicitly indicates they need a moment to think or perform an action (e.g., "just a sec", "give me a minute"). This prevents turn timeout from being triggered during intentional user pauses. See the skip turn tool docs for more information.Text input support: Added text input support in websocket connections via "user_message" event with text field. Also added "user_activity" event support to indicate typing or other UI activity, improving agent turn-taking when there's interleaved text and audio input.RAG chunk limit: Added ability to configure the maximum number of chunks collected during RAG retrieval, giving users more control over context window usage and costs.Enhanced widget configuration: Expanded widget customization options to include text input and text only mode.LLM usage calculator: Introduced tools to calculate expected LLM token usage and costs for agents, helping with cost estimation and planning.
