X-Plane 10.40 Beta 9 is out. If you couldn’t run beta 8 (e.g. it wouldn’t start up or crashed), please update to beta 9. We’ve been thrashing about trying to deal with the problem where X-Plane asks for a user’s product key over and over every time they run. Beta 9 should fix this; if you still see your product key being blanked out frequently in beta 9, please file a bug!

Two known issues:

The transponder commands have been dead for a few betas due to an accidental rename; this will be fixed in beta 10, which should be out in a day or two.

We’re looking at screwed up fuel flow rates in airliners. If you have found an add-on other than the FlightFactor 757 or JAR Designs A330 where fuel flow has changed since 10.36, please file a bug.

Our goal right now is stabilization; what remains for 1040 is to fix the open bugs, not add new features. (So if your question is “will you add X to 10.40”, the answer is almost certainly no.) We want to get to a point where digital download customers can run a non-beta as soon as possible.

I still have at least 30 bugs filed against me; if you filed a bug and it’s not fixed, you do not need to re-file it if it’s not mentioned in the release notes.
