To all those who still use FsAcars (not many, if any): please use it at your own risk (as you always did) or do not use it at all (as you probably already do) until I can confirm that at least it doesn't work worse than before and that there's no new bugs added.
Or, if you would like to help with testing, please use it and report your experiences, but don't be deceived if the same bugs or different bugs spoil your flights.
As far as I could see, most pilots replaced FsAcars with XAcars by now or completely left the VA (which would be sad if it was only for the buggy FsAcars). So it shouldn't be too much of a problem.
