• Full Changelog: https://github.com/emqx/MQTTX/compare/v1.12.0-beta.3...v1.12.0-beta.4

✨ Features 🌈

• Copilot: Added support for Google Gemini models. ([#1923](https://github.com/emqx/MQTTX/pull/1923))
• Copilot: Introduced support for Azure OpenAI. ([#1926](https://github.com/emqx/MQTTX/pull/1926))
• Note on Azure OpenAI Integration: Integrating Azure OpenAI required some specific configurations due to its unique API structure compared to standard OpenAI.
• The `host` field accepts a full URL or the Azure Resource Name.
• The API Version must be specified by appending `?api-version=<your-api-version>` (e.g., `?api-version=2025-01-01-preview`) directly to the host URL/Resource Name in the settings. This parameter is not exposed as a separate configuration field to minimize changes to the current UI and database structure, which lacks a dedicated 'Provider' field.
• Azure models often have a `deployment-` prefix. In Azure, a model corresponds to a deployment. This naming convention helps avoid conflicts with standard OpenAI model names within our current system.
• These implementation details deviate from standard practices but allow Azure OpenAI support within the existing framework. Please take a look at the documentation for detailed setup instructions.

📦 Improvements 💫

• Copilot: Updated the underlying AI SDK to support newer models like GPT-4.1 via the OpenAI integration. ([#1925](https://github.com/emqx/MQTTX/pull/1925))
