40Version 4-0-1 is a bug fix release.
41New feature: attribute @code{ring_cf} for @code{ring}.
42
43@heading News for version 4-0-0
44
45Version 4-0-0 is a milestone relase of Singular.
46The new release series 4 aims for an entirely modularized architecture
47simplifying connectivity with other systems and paving the way
48for parallel computations.
49As  a first step in modularization, the new  release features an internal
50structural separation of coefficient rings and polynomial rings.
51This allows for a flexible integration of new coefficient rings.

53@sc{Singular} 4-0-0's list of new functionality and significant
54improvements further extends that of the 3-1-6/7 prerelease series.
