Poalo,
There are around 144 issues/requests dealt with. I will need to spend some time typing them all out for users info when I can find the time.
Main one is that the database is updated from the tab within database explorer and can be done as often as you like but no more than daily. Check out the satellite layer or the street map layer and lots of bug fixes. Aircraft are set to autoupdate in myflights if you pick up a new one to the database, same with routes.
If you update your own database and dont want your data overwritten you can set the update feature to leave.
Check out the forum for previous versions and whats new in each.
