+# Release Notes - Version 0.0.4
+
+## Overview
+Version 0.0.4 brings significant performance improvements, better memory efficiency, enhanced testing infrastructure, and important bug fixes to the Proxy-Wasm Java Host implementation.
+
+## 🚀 New Features
+
+### Optimizations
+- **Lazy Request Body Loading**: Refactored request body handling so that it's not loaded into memory unless the WASM Pluign needs it
+- **Lazy Response Body Loading**: Refactored response body handling so that it's not loaded into memory unless the WASM Pluign needs it.
+- **Lazy Plugin Startup**: WASM modules now don't get started, until the a request needs to use the module.  
+
+### Enhanced Testing Infrastructure
+- **TomEE Integration Tests**: Added a comprehensive TomEE integration test module to ensure compatibility with TomEE application server
+- **Improved Build Configuration**: Enhanced build setup and configuration management
+
+### Runtime Upgrades
+- **Chicory Runtime v1.4.0**: Upgraded to the latest Chicory WASM runtime for improved performance and stability
+
+## 💥 Breaking Changes
+
+- **Plugin Builder Relocation**: **BREAKING CHANGE** - Moved the builder from the `Plugin` class to the `PluginFactory` class. This change improves the API design but requires code updates:
+  
+  **Before:**
+  ```java
+  () -> Plugin.builder(module)
+      .withName("waf")
+      .build();
+  ```
+  
+  **After:**
+  ```java
+  PluginFactory.builder(module)
+      .withName("waf")
+      .build();
+  ```
+
+
+## 🔧 Improvements
+
+### Documentation
+- **Usage Documentation**: Added comprehensive usage documentation to the README with examples and configuration guidance
+- **CDI Configuration Examples**: Enhanced documentation for CDI-based plugin configuration
+
+### Build System
+- **Dependency Updates**: Updated multiple key dependencies for security and stability:
+  - JUnit 5.12.0 → 5.13.0
+  - Checkstyle 10.23.1 → 10.25.0
