DotNetBrowser 4.2.2

Opening links in external apps

OpenExternalAppParameters now exposes Url property — the URL that is about to be handed to the external application. Previously the callback only provided the localized dialog texts, so there was no way to tell which link triggered it or to apply your own allow/deny rules before calling OpenExternalAppResponse.Open().

browser.Dialogs.OpenExternalAppHandler =
    new Handler<OpenExternalAppParameters, OpenExternalAppResponse>(p =>
    {
        if (IsTrusted(p.Url))
        {
            return OpenExternalAppResponse.Open();
        }

        return OpenExternalAppResponse.Cancel();
    });

We also removed Chromium’s built-in limitation on how often external applications may be launched. Chromium blocks every external-protocol request after the first one until the user performs a new gesture, which meant script-initiated requests were silently dropped and your callback was never invoked for them. DotNetBrowser now routes every request to OpenExternalAppHandler, so a web page can open an external application as many times as needed, and the decision to allow or block it is entirely yours.

As part of the same change, mailto: links are no longer special-cased. Chromium used to launch the default mail client directly, bypassing the callback; mailto: now reaches OpenExternalAppHandler like any other external scheme.

macOS 12 is no longer supported

Starting with this release, macOS 13 (Ventura) is the minimum supported macOS version. This change follows the Chromium 151 upgrade, which dropped support for macOS 12 (Monterey).

Chromium 151.0.7922.72

We upgraded Chromium to a newer version, which introduces 393 security fixes. Among them:
