Alright, I'm gonna try to compile all the features and bugs of this new thingy here. Just so we can have a simple list of what's good and what's bad about replacing your old .dll-thing, you know.
Pros:
Improved widescreen support (fixed some graphical glitches, I guess)
Might allow people to connect to the server better (lower ping and stuff)
Cruise animations for Crusaders/Templars and Valkyries/Wraiths (folding wings)
Automatically timestamps screenshots
Shows actual number of regens on ships with more than 999 regens
Scanner data updates much faster
Selecting a different window while running FL in windowed mode no longer freezes the FL window
Turret zoom, Turret steering, and turret barrel-rolling is possible
Capital ships might not shake anymore when taking hull damage
Cons:
Text and HUD reported as being too big when using widescreen options
Negative cargo space glitch (Mounted weapons on some ships take up cargo space or something)
Game may or may not crash when using /renameme
Cannot enter "catch-up" speed when in formation
Connection or ping or whatever may actually get worse
-logappend, -nohud, and -noflighttext appear to be broken
Transferring credits via the trade menu might crash the game
Let me know if I missed anything. Personally, I don't think I'll be using this new file right now. As much as the new features sound awesome, I don't think I can live without my -logappend.
Hopefully things will get sorted out for 4.86, though.
