## Upcomming 0.9.7.post1

#### New features
The next release will add cost functions between linear operators following [A Spectral-Grassmann Wasserstein metric for operator representations of dynamical systems](https://arxiv.org/pdf/2509.24920).



## 0.9.7.dev0

This new release adds support for sparse cost matrices and a new lazy EMD solver that computes distances on-the-fly from coordinates, reducing memory usage from O(n×m) to O(n+m). Both implementations are backend-agnostic and preserve gradient computation for automatic differentiation.
