How about the more straight forward:

	In previous versions of OSLib os_f was incorrectly defined
	as an 8 bit quantity. This has now been fixed and os_f is
	a 32 bit quantity conforming to the RISC OS API.
	
	Before installing an using this version, check you code only 
	passes os_f to file functions, and you make no invalid casts between
        os_f and byte wide variables, and dont rely on the previous size in
	persistant structures. Performing these changes now is essential
	to ensure your code contines to work with new versions of RISC OS.
	
	All code must be fully recompiled and relinked in this version
	as is the correct practice when installing ALL new libraries.
