FlameRobin 26.6.0 Release Notes

We are excited to announce the release of FlameRobin 26.6.0, which brings major enhancements to FlameRobin's HTML rendering, modernizes UI components with SVG graphics and material icons, improves cross-platform build/runtime compatibility, and resolves critical bugs.

Key Highlights

🌐 Modern HTML Rendering via wxWebView

• Modern Renderer: Replaced the legacy wxHtmlWindow with the feature-rich wxWebView component to display printable HTML content and table info pages. This enables modern CSS layouts, responsive tables, and richer interactive UI elements.
• Graceful Fallback: Implemented automatic fallback to wxHtmlWindow on systems or sandboxed environments (such as specific Flatpak or Snap packages) where the wxWebView backend is unavailable.
• Developer Tools (Inspector): Unconditionally enabled developer tools (Inspector) for the HTML panel in all build configurations, allowing administrators and developers to inspect styling and DOM elements.

🎨 HTML Template Modernization & Google Material Icons

• Vector Graphics: Replaced legacy raster PNG icons (ok.png, redx.png, view.png) in HTML templates with clean, scalable vector SVGs for crisp presentation on HiDPI and 4K displays.
• Material Icons Integration: Integrated the Google Fonts Material Icons system. The template rendering engine dynamically converts SVG image tags to Google Material Icons (<span> tags with .material-icons class).
• Responsive Layouts: Injected a modern, responsive CSS stylesheet dynamically into the rendered pages to ensure text, tables, and icons adjust gracefully to varying window and screen sizes.

🛡️ Local Resource Access & Security Compliance

• Same-Origin Policy Compliance: Resolved Chromium/WebView2 same-origin policy violations (which block access to local file:// resources from different origins) by dynamically writing temporary rendered pages directly inside the HTML templates directory.
• Path Resolution Fix: Fixed a bug causing double prefixing (file:///file:///) of local image assets during URI resolution on Windows.
• Base URL Handling: Fixed local image loading in wxWebView by correctly converting file paths to URIs and setting the appropriate base URL.

🛠️ Build System, GCC, & Platform Compatibility

• Windows MSVC Static Build Fixes: Resolved a static linking error (LNK1104: cannot open file 'WebView2LoaderStatic.lib') on MSVC by extracting and adding the library directories of the resolved WebView2Loader static library to CMake's link search directories (link_directories).
• Linux GUI & Wayland Tweaks: Built GUI dependencies dynamically on Linux to prevent webview runtime crashes. Restricted Wayland-specific GTK3 dependencies strictly to Linux, FreeBSD, and OpenBSD platforms.
• GCC 13+ Compatibility: Added missing <cstdint> header inclusion in fb-cpp to resolve compilation errors under newer GCC toolchains on Linux (e.g., Flatpak GNOME 46 SDK).
• wxWidgets 3.2 Compatibility: Wrapped newer ShowDevTools() API calls in preprocessor version guards to preserve backward compatibility with wxWidgets 3.2.
• Sync/fb-cpp Updates: Restored StatusWrapper forward declarations, getPlan/getLegacyPlan nullptr wrapping, and safeString metadata crash protection in sync-fbcpp.sh and its patch.
