Webview2 109.0.1518.140 ((top)) Jun 2026

To understand the importance of version 109.0.1518.140, one must first understand the WebView2 distribution model. Unlike traditional browser controls (such as the legacy Trident-based MSHTML or CEF), WebView2 utilizes a "Evergreen" distribution model where the runtime is updated automatically by Windows Update. This decouples the application code from the underlying rendering engine.
