    24 @heading User defined types
    25 New types can be defined, see @nref{User defined types}.
     24The version 4-0-0 is the first in the new
     25release series version 4-0.
    27 @heading Handling objects from @code{python}
    28 (Experimental) The new data type @code{pyobject} allows to access some
    29 @code{python} funtionality within @sc{Singular}, see @nref{pyobject}.
    31 Currently, it is only available for those who build Singular from the sources:
    32 Please activate it by typing @code{./configure --with-python}
    33 See @code{./configure --help} for details.

    508 Starting with version 2-0-4, we use NTL (of Victor Shoup) for factoring
    509 univariate polynomials. The multivariate factorization code in libfac/factory
    510 now also works over algebraic field extension.
