Changes since version 3.0:

3.0   --> 3.0.1 (Ivano Primi <ivprimi(at)libero(dot)it>) : 

*   The code of the function Cabs() has been modified
    in order to speed up the execution when working with
    real numbers (the change concerned only the code
    for multiple precision arithmetic).

3.0.1 --> 3.0.2 (Ivano Primi <ivprimi(at)libero(dot)it>) : 

*   The code of the function Cabs() has been improved
    for both double and long-double precision.

*   Fixed a compilation error which occurred when one
    chose to activate the double, the long-double or the high
    precision instead of the multiple precision arithmetic.
    This compilation error was introduced just before releasing
    the version 3.0 of Numdiff .

3.0.2 --> 4.0.0 (Ivano Primi <ivprimi(at)libero(dot)it>) : 

*   New output format. 
    At the same time the code printing the output has been cleaned.

*   Added the -V option for the "verbose" mode.

*   Better handling of the last line of a file.

*   i18n, l10n and documentation have been consequently
    updated.

Changes since version 4.0.0:

4.0.0 --> 4.2.0 (Ivano Primi <ivprimi(at)libero(dot)it>) : 

*   Changed the way the options -V and -b interact when they are both set.

*   Added new tests.

*   Now, when the options -v and -h are both set, Numdiff displays before
    the information about version, Copyright and NO-Warranty and then
    the help message.

*   The Copyright has been updated.

*   Added the tools `ndfilter' and `ndselect'.

*   i18n and italian l10n updated.  

*   The documentation has been consequently updated.

4.2.0 --> 5.0.0 beta1 (Ivano Primi <ivprimi(at)libero(dot)it>) : 

*   Removed the support for double, long double 
    and high precision arithmetic. Now only multiple
    precision arithmetic is available (but it is not a limitation :) ).

*   Removed the option -L, since the tool ndselect made it obsolete.

*   Implemented a synchronization procedure to detect insertions/deletions
    of lines. To accomplish this, source code from GNU diff (diffutils 2.8.1)
    has been used (with the necessary modifications).
    Added the options -f, -z, -Z, -R, -m, -H, -T.

*   Removed the option -F, -X is now used in place of it.	

*   Added new entries to the help which explain how to use the new options.

*   The output format has been slightly changed.

*   Makefile and configuration scripts have been changed, since
    the code has become much more complex than it was.

*   Added more tests to check that the new features are correctly working.
	
*   Change of the license: from GPL version 2 or later to GPL version 3 or later.
    The copyright statement of my files has been consequently updated.
    Also the message shown by 'numdiff -v'.

5.0.0 beta1 --> 5.0.0 beta4 (Ivano Primi <ivprimi(at)libero(dot)it>) : 

*   Added additional information to the report printed by
    the option -S.

*   Now the program can accept the options with argument

    -z INT, -Z INT, -X INT

    as short equivalent forms of 

    -z 1:INT -z 2:INT, 
    -Z 1:INT -Z 2:INT  and
    -X 1:INT -X 2:INT  respectively.

*   The option  -R  has been removed since not useful.
	
*   The option  -s  has now an extended syntax allowing to specify
different sets of field delimiters for the two files to compare.

*   Adoption of the version 1.3 of the GNU Free Documentation License
for the TeXinfo documentation.
	
*   Now the test programs are not anymore distributed together with
    the source code of Numdiff.    
	
WARNING: The TeXinfo documentation has been updated but 
	 the Natural Language Support is still broken.
