Following the release of version 109, Microsoft moved to Edge version 110, which officially required Windows 10 or higher.

The defining characteristic of Edge 109 is its role as the "bridge" between legacy and modern computing. It is the last official release compatible with: Windows 8.1 Windows Server 2008 R2, 2012, and 2012 R2 Once the underlying operating system is updated, Edge

The Chromium project patches dozens of critical flaws every month. Because Edge 109 no longer receives security updates, any vulnerabilities discovered in the Chromium base after late 2023 remain wide open on an Edge 109 browser.

A severe stability issue affected Microsoft's Application Guard feature, designed to isolate untrusted sites in a container. After upgrading to Edge 109 (specifically build 109.0.1519.55 ), users experienced immediate and consistent crashes when attempting to use Application Guard, with one user reporting 52 consecutive failures.
