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.
