 # Changelog
 
+## 2025-11-30 - 4.0.0 - BREAKING CHANGE(watchers)
+Replace chokidar with native platform watchers and add cross-runtime support (Node.js, Deno, Bun); introduce write stabilization and internal glob matching
+
+- Replaced chokidar-based implementation with native file watching APIs (Node.js fs.watch, Deno.watchFs).
+- Added platform-specific watchers: NodeWatcher and DenoWatcher (Bun uses Node compatibility).
+- Implemented polling-based write stabilization (awaitWriteFinish replacement) to avoid duplicate events during writes.
+- Keep glob pattern support by matching events internally using picomatch; base-path extraction used to limit watch scope.
+- API/runtime requirement increased: Node.js >= 20.0.0 is required for native recursive fs.watch.
+- Package/documentation name and examples updated to @push.rocks/smartchok and export the Smartwatch class.

 ## 2025-11-30 - 3.0.0 - BREAKING CHANGE(smartwatch)
 Introduce Smartwatch: cross-runtime native file watching for Node.js, Deno and Bun; rename smartchok to smartwatch and bump major version to 2.0.0

 The module now uses native file watching APIs instead of chokidar, providing cross-runtime support for Node.js, Deno, and Bun.
 
+### Exported Class
+
+The package exports the `Smartwatch` class (not `Smartchok`):
+```typescript
+import { Smartwatch } from '@push.rocks/smartchok';
+```

-A smart wrapper for chokidar 5.x with glob pattern support, RxJS observable integration, and enhanced file watching features.
+A cross-runtime file watcher with glob pattern support for **Node.js**, **Deno**, and **Bun**. Built with native file watching APIs for maximum performance and zero heavyweight dependencies.

 ## Features
 
-🔍 **Glob Pattern Support** - Watch files using glob patterns like `**/*.ts` or `src/**/*.js`
+🌐 **Cross-Runtime** - Works on Node.js 20+, Deno, and Bun
+🔍 **Glob Pattern Support** - Watch files using familiar patterns like `**/*.ts`
 📡 **RxJS Observables** - Subscribe to file system events using reactive streams
 🔄 **Dynamic Watching** - Add or remove watch patterns at runtime
-⚡ **Chokidar 5.x** - Built on the latest chokidar with improved performance
+⚡ **Native Performance** - Uses `fs.watch()` and `Deno.watchFs()` directly
 🎯 **TypeScript First** - Full TypeScript support with comprehensive type definitions
+📦 **Minimal Dependencies** - No heavyweight watcher libraries required
 
 ## Usage

-import { Smartwatch } from '@push.rocks/smartwatch';

 ## How It Works
 
-Since chokidar 4.x+ no longer supports glob patterns natively, smartwatch handles glob pattern matching internally using [picomatch](https://github.com/micromatch/picomatch). This means you get the familiar glob syntax while benefiting from chokidar's efficient file watching capabilities.
+smartchok uses native file watching APIs for each runtime:
 
-When you provide glob patterns:
-1. **Base path extraction** - smartwatch extracts the static base path from each pattern
-2. **Efficient watching** - chokidar watches the base directories
+| Runtime | API Used |
+|---------|----------|
+| **Node.js 20+** | `fs.watch({ recursive: true })` |
+| **Deno** | `Deno.watchFs()` |
+| **Bun** | Node.js compatibility layer |
+
+Since native APIs don't support glob patterns, smartchok handles pattern matching internally using [picomatch](https://github.com/micromatch/picomatch):
+
+1. **Base path extraction** - Extracts the static base path from each glob pattern
+2. **Efficient watching** - Native watchers monitor the base directories
 3. **Pattern filtering** - Events are filtered through picomatch matchers before being emitted
 
+### Write Stabilization
+
+smartchok includes built-in write stabilization (similar to chokidar's `awaitWriteFinish`). When a file is being written, events are held until the file size stabilizes, preventing multiple events for a single write operation.
+
+## Requirements
+
+- **Node.js 20+** - Required for native recursive watching
+- **Deno** - Any version with `Deno.watchFs()` support
+- **Bun** - Uses Node.js compatibility
