When you Google ‘Edge Stable’ today, you’ll get the official download link for the stable version of the Chromium-based Microsoft Edge.
I downloaded it and saw it had the same Chromium version-number als the beta-channel, which most likely means it will be released soon.
Here’s a screenshot for when it gets pulled (hopefully it won’t):
After a year of testing Microsoft finally seems to finalize testing, while they are preparing for launch.
The official downloadlink can be found here:

Fun fact, it uninstalls the Edge version that comes with Windows, which likely means that next versions of Windows will get this version of Edge by default.
The Chrome import functionality works like a charm, so I would absolutely give it a shot.
