[b5bb857] | 228 | Version 4-0-0 is a milestone relase of Singular. |
---|
[4821a3] | 229 | The new release series 4 aims for an entirely modularized architecture |

[b5bb857] | 230 | simplifying connectivity with other systems and paving the way |
---|
| 231 | for parallel computations. |
---|
[1966e4] | 232 | As a first step in modularization, the new release features an internal |
---|
| 233 | structural separation of coefficient rings and polynomial rings. |
---|
| 234 | This allows for a flexible integration of new coefficient rings. |
