 ### deprecation
 ### new features
 ### improvements
+- `torch.view_as_real` and `torch.view_as_complex` now support sparse tensors ([#164964](https://github.com/pytorch/pytorch/pull/164964))
+- Sparse tensor invariants check warning is now raised only once when the check is disabled, instead of on every operation ([#171695](https://github.com/pytorch/pytorch/pull/171695))
 ### bug fixes
+- Fixed `torch.sparse.spdiags` crashing with zero-dimension shapes ([#174052](https://github.com/pytorch/pytorch/pull/174052))
 ### performance
 ### docs
+- Fixed incorrect gradient support documentation for `torch.sparse.mm` and `torch.sparse.addmm` ([#174039](https://github.com/pytorch/pytorch/pull/174039))
