---|
57 | Version 4-0-1 is a bug fix release. |
---|
58 | |
---|
59 | New feature: attribute @code{ring_cf} for @code{ring}. |
---|
60 | |

61 | @heading News for version 4-0-0 |
---|
62 | |
---|
63 | Version 4-0-0 is a milestone relase of Singular. |
---|
64 | The new release series 4 aims for an entirely modularized architecture |
---|
65 | simplifying connectivity with other systems and paving the way |
---|
66 | for parallel computations. |
---|
67 | As a first step in modularization, the new release features an internal |
---|
68 | structural separation of coefficient rings and polynomial rings. |
---|
69 | This allows for a flexible integration of new coefficient rings. |
---|
