We are thrilled to announce the release of ExeOutput for PHP 2025, a major update that introduces powerful new capabilities, significant performance enhancements, and a host of improvements designed to streamline your development workflow.

🚀 Introducing Microsoft Edge WebView2 Support
The flagship feature of version 2025 is the integration of the Microsoft Edge WebView2 rendering engine. You can now choose between the embedded CEF engine and the modern, Windows-native WebView2 runtime, unlocking several key advantages:
- Drastically Reduced EXE File Size: Applications built with WebView2 are only about 20 MB, a massive reduction from the 150 MB required for the CEF engine. This is possible because WebView2 leverages the Microsoft Edge runtime already present on modern Windows systems.
- Seamless System Integration: The WebView2 runtime is included by default in Windows 10 and 11, ensuring a smooth experience for most users. For older systems, a simple, free installer is available.
- Total Flexibility: Switching between WebView2 and CEF is as easy as a single click in the Application Settings, with no code changes required.
⚡️ Performance and Engine Upgrades
This release is packed with core improvements to make your applications faster and more capable:
- Upgraded Chromium Engine (CEF): The embedded Chromium engine has been updated to version 139.0.38 for the latest web compatibility and security.
- New Zstandard Compression: We’ve replaced Brotli with the Zstandard (ZSTD) compression engine for significantly faster multi-threaded file compression during compilation.
- Updated PHP Runtimes: Get initial support for PHP 8.5 (beta 3) and the latest stable versions of PHP 8.4, 8.3, 8.2, and 8.1.
- Restored PHP 5.6 Support: For legacy projects, support for PHP 5 has been restored and PHP 5.6 is available via the Web Update tool.
✨ Key Enhancements and Fixes
- Save HTTP Credentials: Users can now save their login details for sites protected by HTTP Basic Authentication.
- Multi-Instance Execution Fixed: Resolved a critical issue that prevented two different ExeOutput-compiled CEF applications from running simultaneously.
- Popup Stability: Fixed a crash that occurred when opening a popup from another popup and enabled F11 full-screen support for all popups.
- Enhanced Security: The CTRL+U shortcut for viewing source code is now disabled, and dragging external files into popups is prevented.
- Reworked Documentation: The entire documentation has been overhauled and is now available as a comprehensive PDF guide, perfect for offline use, printing, or querying with AI tools.
- And More: This release also includes fixes for URL encoding, the
heexternal://protocol, UPX compression, and numerous other UI and stability improvements.
