    1.28
	The option '--verify-on-error' has been renamed to '--check-on-error'.

	The option synonym '--exit-on-error' has been removed and is no longer
	 recognized.
	In fill and rescue modes, ddrescue now makes a final fsync call on outfile
	 to prevent an early exit if the kernel caches all the writes.
	Option '-t, --show-status' of ddrescuelog now shows the mapfile names at
	 verbosity level 0 if more than one mapfile is specified.
	The variable MAKEINFO has been added to configure and Makefile.in.
    1.27
	A deadlock in command mode when stdout is fully buffered has been fixed by
	 flushing stdout after executing each command. (Reported by Jeffrey Bosboom).
	The new option '-W, --compare-before-write' has been added. It omits
	 superfluous writes in rescue mode.
	 (Suggested by Kajetan Harald Hinner and Petr Slansky).
	Diagnostics caused by invalid arguments to command line options now show the
	 argument and the name of the option.
	The option synonym '--direct' has been removed and is no longer recognized.
	'long long' is now used instead of 'long' for time variables.
	A missing '#include <cstdlib>' has been added.
