Latest release's main focus was a more accurate and robust multiplayer engine. Formation flight is now, hopefully, much more accurate and aircraft interpolation smoother. A couple of bugs were also fixed in the chat UI. Please note that chat messages are now appearing at the top of the screen and scrolling down (reversed).
Thanks to the accuracy of the new multiplayer, I have noticed and taken down a major historical bug that was probably lurking in GEFS from the very beginning. Physics timing was not entirely frame-rate independent: a slower frame-rate would result in a slightly slower aircraft!
This is all fixed and everybody should be able to fly in sync with the same performance.
Have a nice flight!
