UI Improved notifications: Updated notification system to display notifications relevant to the active platform you're viewing, providing a more focused and contextual experience. Agents Platform Dynamic variable transfer destinations: Agent transfers now support dynamic variables for phone numbers and SIP URIs, enabling runtime-determined transfer destinations based on conversation context.MCP tool configuration overrides: Added the ability to create, update, retrieve, and delete custom configuration overrides for specific MCP Server tools, allowing fine-grained control over tool behavior and parameters. Text to Dialogue Timestamps and voice segments: Text to Dialogue now supports timestamped outputs with character-level alignment and voice segment tracking, making it easier to synchronize dialogue with animations or subtitles. Music API Stem separation: Added new stem separation endpoint to isolate different audio components (vocals, drums, bass, instruments) from existing music tracks.Increased prompt length: Music generation now supports prompts up to 4,100 characters, with individual lyric lines supporting up to 200 characters. Security Single-use tokens: Introduced time-limited single-use token generation for secure operations, providing enhanced security for sensitive API operations.
