Removed the API changes to preserve SDL 1.2 stability

WhatsNew

@@ -3,18 +3,6 @@ This is a list of API changes in SDL's version history.
 
 Version 1.0:
 
-1.2.4:
-	Added a new header file: SDL_loadso.h
-	It contains the following functions:
-		SDL_LoadObject(), SDL_LoadFunction(), SDL_UnloadObject()
-	The UNIX esd and arts audio code use these to dynamically load
-	their respective audio libraries.
-
-	Added SDL_LockRect() and SDL_UnlockRect() to lock a portion of a
-	surface.  This may be more efficient than a full lock if you are
-	using a hardware surface and plan to make a few changes to small
-	areas in the surface.
-
 1.2.0:
 	Added SDL_VIDEOEXPOSE event to signal that the screen needs to
 	be redrawn.  This is currently only delivered to OpenGL windows
