I installed version 1.1.3 yesterday evening, directly from version 1.1.1.
I had flown VFR sooner in the day from Toulouse LFCL (France) to Léognan Saucats LFCS, near Bordeaux, following the Garonne River. Although my configuration is reasonnably powerful, (I7 7700K at 4.2 Ghz, 32 Go RAM, Ge Force GTX 1070) the flight is sometimes stuttering, certainly due to the fact that I push all graphics to nearly the max.
Today a trial flight with the new version, from LFCS to LFCO, a small airfield on the edge of the Pyrénées.
First good surprise, the former aircraft registration remained valid, without any need to re-create a new airframe, as in the last versions. The flight time monitoring was also kept from the previous version.
Second good surprise (I am flying XP version 11.26) the flight was noticeably smoother than the one of the previous day, and scanning the panoramic view with my TrackIR did not entail any stuttering, when the scenery was quite similar to the one of the previous day.
In short, a very positive experience. Congratulations!
