 This release introduces vertical tab navigation for settings, new API providers (Groq and Chutes), clickable code references, and numerous UI/UX enhancements, alongside various bug fixes and miscellaneous improvements.
 
+## Gemini 2.5 Pro Preview Model UPDATES (thanks @zetaloop!)
+The `gemini-2.5-pro-preview-05-06` model is now available for Vertex and Gemini providers. Users of `gemini-2.5-pro-preview-03-25` will automatically use the new model, as the older ID now aliases to the latest version on Google's end. No configuration changes are needed to benefit from the update.

 ## Total Settings Navigation Overhaul (thanks @dlab-anton!)
+
 FINALLY the settings interface has been revamped with a new vertical tab layout for a more efficient and intuitive experience:
 - **Effortless One-Click Access**: Navigate between settings sections with a single click.
 - **Optimized for Your Workspace**: Vertical tabs adapt to your VS Code sidebar width, showing full labels or compact icons with tooltips.
 - **Improved Layout and Clarity**: Settings are organized in a clear vertical list for better visibility.
 - **Modernized Look and Feel**: Provides a contemporary and user-friendly way to manage extension settings.

 ## Clickable Code References in Chat (thanks @KJ7LNW!)
+
 Navigating code discussed in AI responses is now significantly easier:
 - **Clickable Code and Filenames**: Any `code` or `filename.extension()` mentioned by the AI is now a clickable link.
 - **Jump to Specific Lines**: Links open the relevant file in your editor and navigate directly to the referenced line number.
 - **Streamlined Code Exploration**: Quickly move from AI explanations to the exact spot in your codebase.

 General UI improvements for a more consistent, visually appealing, and intuitive experience:
 - **Visually Unified Design**: A more consistent look and feel across settings, prompt interactions, and mode selections.
 - **Improved Theme Adaptability**: Better consistency across different VS Code themes.
 - **Streamlined Interactions**: Tidied up UI elements like mode selection and prompt enhancement areas.
 - **Modernized Icons and Tooltips for Code Blocks**: Code block controls (copy, wrap, expand/collapse) now use crisp Lucide icons and feature translated tooltips for better accessibility.
