Thanks. Was just curious was all. 
All in all Hitech is "maintaining" the game. The little fixes and coad upgrades to keep it running clean and safe from hacks is an on going thing. As for "new" things, not for a while except for skins and maps. According to "Lusche" the last plane added was the Tu-2 in January 2014. Maps take a lot of time to build, 3-6 months of work then there is testing, approvals, compiling and uploading to the game. Skins are a bit quicker once you have the basic skin built. Most of the layers they build in on the first plane model can be used on all other models of that plane so they can pop them out pretty quick.
If/when the slow download speeds are corrected, that would be the latest change to the game...

I think that is network issues, some are not under HTC control. Routes, bottle necks, and over sold servers are out of Hitechs control.
