X-Plane 10.40 Beta 10 is posted. This fixes a few big airplane compatibility problems: fuel flow and light size match X-Plane 10.36. (I will post in some detail on this on Monday.) The high-low idle switch isn’t fixed yet – that’s one of the few aircraft compatibility bugs still floating around. See the full release notes for details.
I have seen some bug reports that auto-update is broken on Windows 10; I’m investigating those now. If you try to auto-update and something goes wrong, please do file a bug.
Ideally we will have a release candidate in one week; in practice I am out of the office for a few days this week and it looks like we have Windows-10 specific bugs, so we are more likely to have a release candidate in two weeks.
