Need urgent help with Armature in Blender 2.39

I made a animation for a character for my game on blender 2.39 (17/11 version) but it doesn’t work in P mode (engine).
There’s any version of Blender that support the new armature in the engine?

P.S.: I need the answer urgent, because I’m gonna show my game on a game convention.

The new armature system has not yet been intergrated into the game engine. They do however work in older versions but with the old system of armatures (no new armature features).

remake all the thing??? wow man!!!
