OxygenOS
OxygenOS for OnePlus One has released.OnePlus

If the manual installation of OxygenOS, released earlier this month on OnePlus One, is too much for you - don't worry. OnePlus forum member, svensonic1 has released OxygenOS installer tool, which automatically installs OxygenOS on your OnePlus One, without any hassle. Just click one button and get the ADB installed and USB debugging on.

The tool, as the member notes, installs a custom recovery, unlock bootloader of the phone and installs OxygenOS automatically.

Note that if it gives an error on screen with regards to something from a sideload, just run the sideload.bat file. Check out the following changelog and installation guide. Keep in mind that installation will be at your own risk.
