No official word on an exact date but testing is now being done on the 2.05 release candidates. I am guestimating about 2-3 weeks maximum but probably alot sooner. Here is the 2.05 fix/new feature list so far - it is very extensive:
2.05 Changes
1.Reduce Wind effect by75% default (bdg.txt parameter Wind_Effects_Fraction= 0.25 if users want as is today set to 1.00 )
2.Delete Wind Gust (causes jumps/warps in AI’s performance)
3. Exclude Ju87 from Gearup Call
4.Fix Ju87 Takeoff in Novice from Tangmere
5.Prevent CTD, in TargetClosureGreaterThan
6.Prevented Campaign from being used with Novice AI
7.Reduced the Number of Fighter blowups to less than 10%
8.Prevented CTD in RemoveFromSector when sector is NULL
9.Added a Novice_Gunnery_Predictor feature (Bdg.txt control)
10.Prevented crashes on the runway at air fields (the age old ObjectAdds renaming workaround problem)
11. MultiSkin Switch in the BDG.txt added (4 positions see bdg.txt) (Osram)
12. MultiSkin preload added for 250M video card (Osram)
13. MultiSkin preload added for 128M video card (Osram)
14. Added code to smooth the scissor maneuvre
15. Added BDG.txt Rain (off/on) switch for inclement weather at user request
16. Fix/prevented CTD in AssignFuelTruck()
17. Added Transition to the end of Disengage Maneuvre
18. Added Death_Breaks_Padlock feature that Reto started
19. Prevented a CTD in DecisionMessage (non-repeatable)
20. Added Bdg.txt parameters for “Spin” control
Spin_AOA_Control = 17.500 (degrees default)
Spin_Rotational_Velocity_Control = 14.325 (degrees/Sec. default)
21.Fixed TrackIR ID 7001 (Thanks to Retro)
22.Fixed TIR-VE Re-Center Position in Spit (thanks to Retro)
23. Fixed AssignFuelTruck CTD back in Auto_Land
24.Fixed CTD in NodeData caused by a bad pointer
25. Fixed 128MB Video card VRAM issue (Osram)
26. Fixed CTD when selecting Historic Kenley mission for low Alt Do17 then selecting Cabbage5
27. Suppress the Unresolved UIDS error in BFIELDS. Can not be any worse than now
28. Added Bdg.txt AI_Always_Sees_Enemy so the AI A/C will be seen (default=OFF) which can be used to assist the “engage” issues.
29. Added Bdg.tx Wingmen_Always_Sees_Enemy so the wingmen will always see the enemy AI when a R-3-1 (bandits) is issued (default=OFF)
30. Implemented a “attack my target” which is a last resort “engage” using the R-3-5 (Help) so that your wingmen will attack a fight of enemy AI’s when you have first padlocked an enemy AI A/C.
31. Fixed the peel off maneuver so it will fly directly toward the enemy target after the peel off for a more timely engage.
32. Fixed Hurricane white nose with Multiskin
33. Moved Hurricane pilot forward
34. Added "version 2.05" to the opening UI screen
35. Adjusted LOD for HANGR2
36. Improved ground explosions with more dynamic shockwaves and fireballs
37. Improved bullet ground hit effects
38. Optimized burning trail effects for better framerates
39. Fixed all the disengage bugs so the wingmen AI A/C and enemy AI A/C stay engaged and fight until the “go Home” criteria is met (no Ammo, low fuel, or major damage that prevents a good fight). Note: skill and morale will not be used to determine whether to engage but are used to determine how well the AI fight.
40. Fixed a personal threat smoothing issue where an AI has a hit or near miss on a target by adding a transition (old method had no transition so jumps could occur depending the state of the maneuver when the personal threat shot was taken).
41. Fix a CTD GetWeaponLauncher caused by a null pointer.
42. Added the “blrtp” (behave like Rowand Type Plane) feature as a step along the path to being able to add new A/C without having to change C++ code.
43. Fixed repeat CTD and the funny loading screen issue.
As part of the update there will be options to install MAJOR MAJOR improvements in the FMs of the Spitfire, ME109 and Hurricane, or to keep the original ones. User evaluations thus far have significantly favored the new FMs.
