This new release contains several new features and bug fixes. Among the new features we have a new submodule ot.batch that contains batch parallel solvers for several OT problems including Sinkhorn, Gromov-Wasserstein and Fused Gromov-Wasserstein. This new submodule can be used to solve many independent OT problems in parallel on CPU or GPU with shared source and target support sizes. We also implemented a new Nystrom kernel approximation for the Sinkhorn solver that can be used to speed up the computation of the Sinkhorn divergence on large datasets. We also added new 1D solvers for Linear circular OT and new solvers for free support OT barycenters with generic cost functions and for barycenters between Gaussian Mixture Models (GMMs). We also implemented two solvers for partial Fused Gromov-Wasserstein problems based on conditional gradient and projected gradient descents.

Finally we have updated the documentation to reflect the new generic API and reorganized the examples gallery.
