44
[b5bb857]45Version 4-0-0 is a milestone relase of Singular.
[4821a3]46The new release series 4 aims for an entirely modularized architecture
[b5bb857]47simplifying connectivity with other systems and paving the way
48for parallel computations.
[1966e4]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.
[7af0cb5]52
[1966e4]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.
