Are some of these old bugs fixed in 2.5?

About to ditch 2.2 and install 2.5...

In 2.2 and 2.1 - I have noticed a few glitches:

1.) Occasional (Intermittent) Floating autogen when flying over a large metropolitan area

2.) Carrier wake (Javier Carriers) flickers

3.) Some third party aircraft (i.e. Aerosoft) have exterior lighting issues - i.e. taxi light not illuminating ground, cannot see wingtip lights from inside cockpit, etc.

Other than those mentioned above, it's been a good experience with 2.1 & 2.2!!!

Have these bugs been fixed up in 2.5???

Thanks!
