Hot Start TBM-900 for X-Plane 11, Update Tracking

Since the initial release of the Hot Start TBM-900 back in October 2018, the team have proven themselves to be one of the most supportive and responsive development groups within the industry.  Accordingly, Hot Start has now released yet another product update bringing the software up to Version 1.1.9. In an effort to track ongoing version status, we will continue to periodically update this post as well as consolidate changelog information.

Please see below for a complete historical changelog current as of April 26, 2019.
