From SWS:

"Our first P3Dv5 compatible product, the PBR Phantom, is out! Featuring brand-new cockpit textures, the definitive Cold War fighter is ready to take to the virtual skies again!
The v5 upgrade of the Phantom is free for customers who have bought the v4 version of the PBR Phantom.
With that opportunity, we will be running a 25% off our catalogue until Sunday, July 12 at 21:00GMT on our e-shop"
