Yes, it's in testing right now to make sure it doesn't introduce other bugs and works as intended. If you want to test things yourself, you do have access to the test branch. Just hit settings and in FGU click the ADVANCED tab and choose 'Test' from the build channel drop down menu. In FGC click the 'Test' radio button in the mode group at the bottom. Then in both cases allow the program to complete the update, and you'll be in the test environment. When you want to return to the live environment just do the same but choose live instead and let the program update.
