[ANNOUNCEMENT] [announcement] updated singular-*-3.1.0-1

Version 3.1.0-1 of "Singular" has been uploaded.


SINGULAR is a Computer Algebra System for polynomial computations with
special emphasis on the needs of commutative algebra, algebraic
geometry, and singularity theory.

(You will also find this and more detailed information at

    * new coefficients: Z, Z/m, Z/(2^n) (see Rings and orderings)
    * new handling of the default argument in libraries
      (see Parameter list)
    * ESingular updated for emacs 22
    * licences for all parts of SINGULAR clarified (see Preface)

New SINGULAR functions

    * new command: kernel (see kernel)
    * new command: sqrfree (see sqrfree)
    * command changed: the first argument to monitor should be an
      ASCII link. (see monitor)
    * command extended: eliminate: variables to eliminate may also
      be given as intvec. (see eliminate)

Internal Changes

    * handling of large input for std improved
    * interred implemented in a different way
    * kbase honors the attribute "isHomog"
    * jacob accepts modules and matrices
    * gcd over algebraic extensions of the rationals implemented
      in a different way
    * new build target: libsingular.a (for gfan etc.)
    * code variants now depend on CPU type, not OS
    * better test for built-in limits (see Limitations)
    * operator new(size_t,const std::nothrow_t&) now also

New SINGULAR libraries

    * surfex: new version 0.90
    * new library: redcgs.lib
    * new library: tropical.lib
    * new library: polymake.lib
    * new library: sing4ti2.lib
    * new library: decodegb.lib
    * new library: dmodapp.lib
    * new library: bfun.lib global
    * new library: freegb.lib
    * new library: jacobson.lib
    * contributed library: cimonom.lib
    * contributed library: phindex.lib

Changed SINGULAR libraries

    * normal.lib ( normal_lib): changed structure of the result,
      new algorithms have been implemented which improve performance
    * elim.lib ( elim_lib): elim, nselect, select, select1:
      changed syntax
    * homolog.lib: kernel renamed to hom_kernel.
    * matrix.lib ( matrix_lib): new commands for computing
      symmetric/exterior powers/bases
    * surf.lib: new command surfer: interface to program surfer
    * teachstd.lib ( teachstd_lib): spoly works now in non-commutative
      algebras and standard can thus be used there. However, since
      product criterion is a priori not applicable in the
      non-commutative case, one may want to disable it first
    * many changes of names in libraries (to have a more consistent
      naming scheme)
