### 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.

### API

#### TLS

Our TLS endpoints no longer allow some older and insecure cipher modes. Most clients should not be affected as they already negotiate a modern cipher mode.
