 ### Added
 
+- Added support for `EdgeIndex.unbind` ([#9298](https://github.com/pyg-team/pytorch_geometric/pull/9298))
 - Integrate `torch_geometric.Index` into `torch_geometric.EdgeIndex` ([#9296](https://github.com/pyg-team/pytorch_geometric/pull/9296))
 - Support `EdgeIndex.sparse_narrow` for non-sorted edge indices ([#9291](https://github.com/pyg-team/pytorch_geometric/pull/9291))
