| 6 | +Features |
| 7 | +-------- |
| 8 | + |
| 9 | +- adds functionality to compute symmetries of entire symmetry detection graph rather than just the restriction to variable nodes |
| 10 | + |
| 11 | +Interface changes |
| 12 | +----------------- |
| 13 | + |
| 14 | +### Deleted and changed API methods |
| 15 | + |
| 16 | +- SCIPcreateSymgraph() receives an additional argument to specify an epsilon value that is used for epsilon-comparisons |
| 17 | + |
| 18 | +### New API functions |
| 19 | + |
| 20 | +- added SYMcomputeSymmetryGeneratorsNode() to compute generators of the automorphism group of an entire (node set) of a symmetry detection graph |
| 21 | + |
| 22 | +### Data structures |
| 23 | + |
| 24 | +- struct SYM_Graph receives an additional field to specify an epsilon value that is used for epsilon-comparisons |
| 25 | +- new enum SYM_GROUPTYPE to encode which symmetry group of a symmetry detection graph is computed |
