31
32Version 4-0-1 is a bug fix release.
33New feature: attribute @code{ring_cf} for @code{ring}.
34
35@heading News for version 4-0-0
36
37Version 4-0-0 is a milestone relase of Singular.
38The new release series 4 aims for an entirely modularized architecture
39simplifying connectivity with other systems and paving the way
40for parallel computations.
41As  a first step in modularization, the new  release features an internal
42structural separation of coefficient rings and polynomial rings.
43This allows for a flexible integration of new coefficient rings.

45@sc{Singular} 4-0-0's list of new functionality and significant
46improvements further extends that of the 3-1-6/7 prerelease series.
