# Changelog - v1.3.0 (2025-12-27)
This is a major architectural release that modularizes the entire codebase for better maintainability, testing, and extensibility.
## ⭐ New Features
- **Modular Architecture**: The codebase is now organization into focused modules in `src/`:
- `src/index.js`: Main entry point and MCP protocol handler
- `src/browser.js`: Centralized browser connection and state management
- `src/tools/`: Dedicated modules for each tool category (navigation, interaction, media, etc.)
- `src/utils.js`: Shared utilities
- **Plugin System**: New `plugins/` directory allows adding specialized tool modules that are auto-discovered by `src/tools/index.js`.
- **Improved Test Suite**: Tests are now organized in the `tests/` directory with `fixtures/`.
- **Reduced Bundle Size**: The main entry point is now cleaner and easier to maintain.
## 🛠 Refactoring
- **Source Code**: Moved all source code from the root directory to `src/`.
- **Entry Point**: Replaced the monolithic `browser-mcp-server-playwright.js` with `src/index.js`.
- **Tool Logic**: Extracted tool implementations from the main server file into:
- `src/tools/navigation.js`
- `src/tools/interaction.js`
- `src/tools/media.js`
- `src/tools/system.js`
- `src/tools/console.js`
- `src/tools/info.js`
- `src/tools/mouse.js`
- `src/tools/keyboard.js`
- `src/tools/pages.js`
- **Utilities**: Extracted `debugLog`, `loadPlaywright`, and `findChromeExecutable` to `src/utils.js`.
## 🧹 Cleanup
- Removed the legacy `browser-mcp-server-playwright.js` wrapper file.
- Removed old `.tgz` build artifacts.
- Updated `package.json` to point `main` and `bin` to `src/index.js`.
## 🧪 Testing
- Verified all 36 tools function correctly after modularization.
- Verified MCP protocol communication.
- Verified browser connection strategies (Antigravity, System Chrome, Playwright).
