Emalice, This does not pertain to X-Plane 10 only. The plug-in is utilized in both versions, and while the engine model is not as glaringly bad in 9, there are still plug-in issues. Rather than ever give updates we also could have opted to stay mum on the entire update process and you would have never known a FREE one was coming, however, we believe it is both good and fun to keep people informed. If it's caused you to become upset instead then we apologize. There was no lie that came about when Tom stated he was working on the manual and had thought he was done. However, as he was putting the manual itself through "the paces," there were evident issues becoming apparent in the plug-in for both 9 AND 10. Releasing a product separately is just not going to happen.
