Many more patches are coming thanks to a very dedicated group with links to Maddox games. We will see radar, more planes, triggers and much more in 5.0 and beyond. They(Daidalos team) are now responsible for making official patches with maddox only doing flightmodel and graphics tweaks and ofcourse the final testing and compiling.
AAA is short for All Aircraft Arcade , a modding website that bundles tons of mods into one Unified Installer (UI) and releases them as an easy to use pack.
UI 1.1 has all AI aircraft in IL2 as flyables, many totally new aircraft, maps, graphics tweaks and alot more. UI 1.2 will be a followup with stuff like new 109's, mig-15, F9F, more maps, moving dogfight servers, rearming/refuelling at airbases etc.
Though it seems the mods conflict with 4.09 final till they get updated. So for now I would stick to 4.09m and then try UI 1.2 once it's released and compatible with 4.09.
Happy flying
