v0.4.0

Browser Operator Core v0.4.0 Release Notes

Browser Operator Core v0.4.0 represents a transformative leap in AI agent capabilities. By introducing a virtual file system and web rendering engine, agents can now handle complex, multi-step workflows that were previously impossible. Agents can manage their own temporary state across long-running tasks, generate rich interactive content like reports and presentations, and create learning materials such as interactive flashcards - all within the browser environment.

✨ New Features

Extended Agent Intelligence & Persistence

• Stateful Long-Running Tasks: Agents can now use the file system to maintain context and temporary states across extended workflows, breaking through previous memory limitations
• Complex Task Orchestration: Multi-step processes that require intermediate data storage and retrieval are now possible
• Persistent Working Memory: Agents can save, retrieve, and update information throughout lengthy operations without losing context

Virtual File System & Web Asset Management

• In-Browser File Storage: New virtual file system enables creation, storage, and management of code files directly in the browser using IndexedDB
• Session-Scoped Storage: Files are properly isolated per DevTools session, ensuring clean workspace separation
• 8 New Development Tools:
  • Create, read, update, and delete files
  • List and check file existence
  • Render web applications in sandboxed iframes
  • Retrieve form data and user interactions from rendered apps

Web Application Rendering

• Live Preview Capability: Instantly render HTML/CSS/JavaScript applications within isolated iframes
• Interactive Reports: Agents can generate full HTML/CSS/JavaScript reports with charts, graphs, and interactive elements
• Dynamic Presentations: Create slide decks and presentation materials that can be viewed and navigated in real-time
• Sandboxed Execution: Secure iframe implementation with proper content isolation
• Data Retrieval: Automated collection of user interactions and form submissions from rendered applications
