Fix depgraph's package selection logic to choose the highest version |
| 2 |
involved in a slot conflict, for correct operation of conflict_downgrade |
| 3 |
logic in the dep_zapdeps function which was introduced in commit |
| 4 |
a9064d08ef4c92a5d0d1bfb3dc8a01b7850812b0. This will prevent incorrect |
| 5 |
re-ordering of || deps in dep_zapdeps, as reported in bug 554070. |
