Прекращение поддержки Microsoft Edge и Webview2 для Windows 7 и Windows 8/8.1 (Обновлено)

В связи с прекращением поддержки Windows 7 Extended Security Update (ESU) и Windows 8/8.1 10 января 2023 года, а также прекращением поддержки Google Chrome для Windows 7 и Windows 8/8.1, браузер Microsoft Edge версии 109 и Webview2 Runtime версии 109 будут последними соответствующими версиями, поддерживающими эти операционные системы. Кроме того, WebView2 SDK версии 1.0.1519.0 и выше больше не будет поддерживать Windows 7 и Windows 8/8.1.

Как Microsoft Edge версии 109, так и Webview2 Runtime версии 109 запланированы к крелизу на неделе 12 января 2023 года (чтобы узнать больше, смотрите расписание релизов). Хотя Microsoft Edge и Webview 2 Runtime версий 109 и ранее будут продолжать работать в этих операционных системах, эти версии не получат новых функций, будущих обновлений безопасности или исправлений ошибок.

Версия 109 Microsoft Edge также станет последней поддерживаемой версией для Windows Server 2008 R2.

Поддержка в Windows Server 2012 и Windows Server 2012 R2

Microsoft Edge версии 109 будет последней поддерживаемой версией в Windows Server 2012 и Windows Server 2012 R2 (версия 110 и более поздние версии будут недоступны). Версия 109 будет получать критические исправления безопасности и исправления известных ошибок эксплойтов до 10 октября 2023 года. WebView2 Runtime версии 109 будет поддерживаться таким же образом.

Исправленные и вечнозеленые версии WebView2 Runtimes

Эта временная шкала окончания поддержки применяется как к вечнозеленой, так и к исправленной версиям WebView2 Runtime.

Ранее установленные Evergreen WebView2 Runtimes будут обновляться до версии 109 в обычном режиме, но после этого обновление не продолжится. После окончания поддержки, при последующих попытках установить Evergreen WebView2 Runtime на Windows 7 и Windows 8/8.1, будет установлена версия 109.

Исправленные версии WebView2 Runtime выше 109 не запустятся в Windows 7 и Windows 8/8.1 и не должны использоваться в этих операционных системах.

Получение новых версий Microsoft Edge и Webview2 Runtime

Чтобы получить новые версии Microsoft Edge или Webview2 Runtime с обновленной функциональностью и безопасностью, выполните обновление до Windows 10 или более поздней версии.

Microsoft также призывает разработчиков прекратить поддерживать Windows 7 и Windows 8/8.1. Microsoft признает, что некоторым разработчикам это может быть нелегко сделать, однако прекращение поддержки этих операционных систем поможет обезопасить конечных пользователей от потенциальных угроз безопасности и рисков, поскольку поддержка обеих операционных систем прекращается 10 января 2023 года.

Microsoft Edge WebView2 is Now Generally Available

Microsoft announced today that its the first version of its Chromium-based Edge WebView2 developer technology is now generally available.

“We are excited to announce that Microsoft Edge WebView2 for Win32 C/C++ is generally available and ready for use in production applications,” the Microsoft Edge team announced. “With today’s announcement, we are officially releasing a forward-compatible WebView2 SDK along with production-ready WebView2 Runtime. These can be used in any Win32 C/C++ application, and are supported across existing Windows versions.”

What’s not available yet, however, is WebView2 for .NET—meaning Windows Forms and Windows Presentation Foundation (WPF)—and WinUI 3. Both are currently in preview; WebView2 for .NET is expected by the end of 2020 and WebView2 for WinUI 3 will ship whenever WinUI 3 is released in 2021.

For those unfamiliar, WebView2 is the new version Microsoft’s embedded web control. Now built on the Chromium version of Microsoft Edge, WebView2 lets Windows app developers access to the latest web technology in existing and new desktop apps. (And, soon, .NET and WinUI 3 apps.) Today, developers can deploy WebView2 using a so-called evergreen distribution model in which it is always kept up-to-date automatically by Microsoft. But by the end of 2020, Microsoft will make a fixed distribution version of WebView2 available for those with strict compatibility requirements.

Going forward, new releases of WebView2 will be released alongside new versions of Microsoft Edge every six weeks.
