Removals and Changes

This section lists the most important changes in Version 2.7. Other minor changes are listed in the relevant sections.

• The category of elliptic curves CurveEll and their points CurveEllPt has been changed to CrvEll and CrvEllPt.
• The procedure SetSeed and function GetSeed have changed: see the section `Random Object Generation' below.
• The parameters for the function ClassGroup for algebraic number fields and their orders have changed.
• The procedure Verify for algebraic number fields and their orders has been removed, since it is no longer necessary.
• The obsolete function GroebnerWalk has been removed and the parameters for Groebner have changed (see below).
• The function NullSpace has been renamed to Nullspace, which is more standard. NullSpace is supported for backwards compatibility in this version. The function RowNullspace has also been renamed to NullspaceOfTranspose.
• The basic algebra creation functions MakeBasicAlgebra and pGroupToBasicAlgebra have been renamed to BasicAlgebra.
