### Agents Platform

- **Azure OpenAI custom LLM support**: Added support for Azure-hosted OpenAI models in custom LLM configurations. When using an Azure endpoint, a new required field for [API version](https://elevenlabs.io/docs/api-reference/agents/create#request.body.conversation_config.agent.prompt.custom_llm.api_version) is now available in the UI.
- **Genesys output variables**: Added support for output variables when using [Genesys integrations](/guides/elevenagents-phone-numbers-c-caa-s-integrations-genesys), enabling better call analytics and data collection.
- **Gemini 2.5 Preview Models Deprecation**: [Models](https://elevenlabs.io/docs/api-reference/agents/create#request.body.conversation_config.agent.prompt.llm) `gemini-2.5-flash-preview-05-20` and `gemini-2.5-flash-preview-04-17` have been deprecated in Agents Platform as they are being deprecated on 15th July by Google. All agents using these models will automatically be transferred to `gemini-2.5-flash` the next time they are used. No action is required.
- **WebRTC rollout**: Began progressive rollout of WebRTC capabilities for improved connection stability and performance. WebRTC mode can be selected in the React SDK and is used in 11.ai.
- **Keypad touch tone**: Fixed an issue affecting playing keypad touch tones on Twilio. See [keypad touch tone documentation](/guides/elevenagents-customization-tools-system-tools-play-keypad-touch-tone).

### Voices

- **Language collection navigation**: Added quick navigation from language preview collections to view all available voices in that language, making it easier to explore voice options by language.

### Text to Voice

- **Preview streaming**: Added new streaming endpoint for Text to Voice previews, allowing real-time streaming of generated voice previews via `/v1/text-to-voice/{generated_voice_id}/stream`.
- **Enhanced voice design**: Added [`stream_previews`](https://elevenlabs.io/docs/api-reference/text-to-voice/design#request.body.stream_previews) option to voice design endpoint, enabling streaming-only preview generation for improved performance.
- **Improved parameter controls**: Enhanced [`loudness`](https://elevenlabs.io/docs/api-reference/text-to-voice/design#request.body.loudness), quality, and guidance scale parameters with better control options for more precise voice generation.

### ElevenCreative Studio

- **Podcast customization**: Added support for [intro](/guides/api-reference-studio-create-podcast#request.body.intro) and [outro](/guides/api-reference-studio-create-podcast#request.body.outro) text in podcast creation, along with custom instructions prompts for better style and tone control.
