 ## [2.0.5] - 2022-MM-DD
 ### Added
+- Added `predict()` support to the `LightningNodeData` module ([#4884](https://github.com/pyg-team/pytorch_geometric/pull/4884))
 - Added `time_attr` argument to `LinkNeighborLoader` ([#4877](https://github.com/pyg-team/pytorch_geometric/pull/4877))
 - Added a `filter_per_worker` argument to data loaders to allow filtering of data within sub-processes ([#4873](https://github.com/pyg-team/pytorch_geometric/pull/4873))
 - Added a `NeighborLoader` benchmark script ([#4815](https://github.com/pyg-team/pytorch_geometric/pull/4815))
