Breaking changes
Windows registry extensions
On Windows, DotNetBrowser no longer installs extensions registered in the Windows registry. This prevents an embedded browser from loading extension code that the application did not request.
Applications that need an extension should install it through their own application-controlled extension setup instead of relying on Chrome extension registry entries.
Chromium 154.0.8037.58
We upgraded Chromium to a newer version, which introduces 166 security fixes.
- CVE-2026-91726: Out of bounds read in WebGL
- CVE-2026-91721: Use after free in Internals
- CVE-2026-91749: Use after free in Workers
- CVE-2026-93374: Use after free in Dawn
- CVE-2026-91724: Use after free in Input
See the Chromium release announcements for more details.
Quality enhancements
- Fixed memory growth in the .NET process when an application made repeated DOM or other calls from a long-running event handler.
- Fixed a memory leak that kept disposed page contexts, DOM contexts, and JS contexts in memory after navigation.
- Fixed a Chromium process crash that could occur after a web page started a
Presentation API request and the application answered
StartPresentationHandler. - Compressed response bodies written by
UrlRequestJobinInterceptRequestResponseare now decoded according to theContent-Encodingheader. This lets intercepted HTML, scripts, and styles load as decoded content instead of raw compressed bytes. - Fixed
Browser.DevTools.Show()on macOS so the DevTools window is visible again. - Disabled network requests from Chromium’s on-device AI component to Google’s update service.
- Improved native input handling for complex IMEs on Windows and Linux.
