If you're using a Snapdragon-powered Windows 10 PC, then you're probably looking forward to Microsoft's Chromium-powered Edge browser. Unfortunately, it's not available in an ARM64 flavor just yet, so if you install it, you'll still get the emulated x86 version.
As seems to commonly be the case, a build leaked today, so those living on the edge (pun intended) can try it out. The signatures on the installation file do say that it's from Microsoft, although any leaked build is installed at your own risk. Apparently, there's no updater included either.
Just about every version of Microsoft's Chromium-powered Edge browser was leaked before it was publicly available. That includes the original Dev and Canary builds for Windows 10, Edge Beta, and the versions for macOS. This just adds to the collection.
The leaked version that's available for ARM64 PCs today is version 18.104.22.168, and it's from the Canary branch. The version number is on par with the current Edge Canary builds for x86 and AMD64, although presumably, you won't get future updates.
