Ideal Flight Professional for Prepar3D v4 (10.027eb) has survived the initial surge of take-up with no reports of problems so far. It's a new release and I'm sure something will pop up and need adjustment. Currently I'm moving through the app retesting and evaluating other ideas and requests. Any problems surfacing will be handled with a release 10.027ec in a timely manner.
Feature matching releases of Ideal Flight 10 (FSX/FSX:SE) and Ideal Flight 10 Professional (P3D v2/3) are coming shortly, although these can be obtained now from the Preview discussion in the New Builds section.
I know it will disappoint some but unfortunately extending IF10 Pro P3D v2/3 to handle P3D v4 surfaced far too many problems, and the risks to the stability of the code were too great - a new app was demanded to concentrate on the Prepar3D v4 platform going forward - a vast amount of work was required for this implementation. It's a new paid-for app, support works the same way as it does for IF10 including updates as required and the same price to all.
Prepar3D v4 brings 64bit code and Unicode character sets. At this time Ideal Flight Professional for Prepar3D v4 will not install to a Windows UserName with Unicode character sets outside the standard 8 bit set. However all Unicode functions are in place and working in Ideal Flight Professional. A UserName Unicode version of IF is working in the development stage and may become available if demand requires. At the moment the app is deliberately being kept to the more simple codebase while new to simplify support for the time being.
Thanks to everyone supporting Ideal Flight!
