🚀 Portable Mode & Enhanced Features

This release introduces Portable Mode as the headline feature, making it easy to run the AI-Enhanced Arduino IDE anywhere without a full system install. It also syncs with upstream Arduino changes, improves library handling defaults, and includes multiple UI and agent-level refinements for a smoother overall experience.

✨ Key Features & Additions

• Portable Mode (NEW)
  New installer option creates a fully self-contained setup with:

  • Application
  • Configuration
  • Data
  • Sketchbook

  Designed for true plug-and-play portability. Includes a custom installer finish page for quick setup.

• Auto-Install Library Dependencies
  Required libraries are now installed automatically by default, reducing manual steps and speeding up development.

• Boards Manager – Installed Filter
  Easily view and manage only installed boards for a cleaner Boards Manager experience.

• Arduino CLI Upgrade
  Updated to Arduino CLI v1.3.1 for improved compatibility and performance.

• UI & Widget Improvements

  • Fixed input focus and caret jump issues
  • Textareas now clear correctly after sending
  • Improved robustness for streaming responses and agent handling

• Other Enhancements

  • Simplified and cleaned up internal code structure
  • Removed unused UI elements (e.g. welcome dialog)
  • Added Wayland troubleshooting documentation for Linux users
  • Applied security fixes and code-audit improvements

🐞 Bug Fixes

• Replaced null characters in copied Serial Monitor output
• Escaped asterisks in error messages to ensure proper notification rendering
• Multiple refactors improving type-safety, modularity, and reducing debug noise

🚀 Spectre AI — First Public Release

I'm excited to announce the first public release of Spectre AI — an intelligent assistant integrated directly into Arduino IDE 2.x.
Spectre brings AI-powered code assistance, context-aware suggestions, and autonomous agent capabilities to your Arduino development workflow.

🤖 What is Spectre AI?

Spectre AI is an extension for Arduino IDE 2.x that provides:

• AI-Powered Code Assistance
  Intelligent code suggestions, generation, and explanations powered by Google Gemini models.

• Context-Aware Responses
  Spectre understands your project structure, board configuration, coding patterns, and IDE state.

• Autonomous Agent Mode
  Execute multi-step tasks such as refactoring, running test sequences, or programming devices, with built-in recovery and action logging.

• Long-Term Memory
  Persistent session memory that retains project context across sessions.

🔑 Key Features

🔄 Dual Model Support

Choose between:

• gemini-2.5-flash — rich, detailed responses
• gemini-2.5-flash-lite — cost-efficient interaction

🧠 Intelligent Memory System

A three-tier memory architecture manages context efficiently:

• Rolling Buffer — stores recent conversation with full fidelity
• Memory Bank — keeps summarized long-term context
• Meta-Compression — compresses older summaries for maximum efficiency

🛠️ Agent Mode with Safety Guardrails

Run automated multi-step operations with:

• Retry & rollback policies
• Loop guards to prevent infinite execution
• Full action logging
• Idempotent operations where possible

📦 Library & Board Management

Install libraries and board packages directly through the assistant.

💾 Session Persistence

Your conversation history and project context persist across IDE restarts, with import/export options for portability.
