-## 0.9.0
-*April 2023*
-
-This new release contains so many new features and bug fixes since 0.8.2 that we
-decided to make it a new minor release at 0.9.0.
-
-The release contains many new features. First we did a major
-update of all Gromov-Wasserstein solvers that brings up to 30% gain in
-computation time (see PR #431) and allows the GW solvers to work on non symmetric
-matrices. It also brings novel solvers for the very
-efficient [semi-relaxed GW problem
-](https://pythonot.github.io/master/auto_examples/gromov/plot_semirelaxed_fgw.html#sphx-glr-auto-examples-gromov-plot-semirelaxed-fgw-py)
-that can be used to find the best re-weighting for one of the distributions. We
-also now have fast and differentiable solvers for [Wasserstein on the circle](https://pythonot.github.io/master/auto_examples/plot_compute_wasserstein_circle.html#sphx-glr-auto-examples-plot-compute-wasserstein-circle-py) and
-[sliced Wasserstein on the
-sphere](https://pythonot.github.io/master/auto_examples/backends/plot_ssw_unif_torch.html#sphx-glr-auto-examples-backends-plot-ssw-unif-torch-py).
-We are also very happy to provide new OT barycenter solvers such as the [Free
-support Sinkhorn
-barycenter](https://pythonot.github.io/master/auto_examples/barycenters/plot_free_support_sinkhorn_barycenter.html#sphx-glr-auto-examples-barycenters-plot-free-support-sinkhorn-barycenter-py)
-and the [Generalized Wasserstein
-barycenter](https://pythonot.github.io/master/auto_examples/barycenters/plot_generalized_free_support_barycenter.html#sphx-glr-auto-examples-barycenters-plot-generalized-free-support-barycenter-py).
-A new differentiable solver for OT across spaces that provides OT plans
-between samples and features simultaneously and
-called [Co-Optimal
-Transport](https://pythonot.github.io/master/auto_examples/others/plot_COOT.html)
-has also been implemented. Finally we began working on OT between Gaussian distributions and
-now provide differentiable estimation for the Bures-Wasserstein [divergence](https://pythonot.github.io/master/gen_modules/ot.gaussian.html#ot.gaussian.bures_wasserstein_distance) and
-[mappings](https://pythonot.github.io/master/auto_examples/domain-adaptation/plot_otda_linear_mapping.html#sphx-glr-auto-examples-domain-adaptation-plot-otda-linear-mapping-py).
-
-Another important first step  toward POT 1.0 is the
-implementation of a unified API for OT solvers with introduction of [`ot.solve`](https://pythonot.github.io/master/all.html#ot.solve)
-function that can solve (depending on parameters) exact, regularized and
-unbalanced OT and return a new
-[`OTResult`](https://pythonot.github.io/master/gen_modules/ot.utils.html#ot.utils.OTResult)
-object. The idea behind this new API is to facilitate exploring different solvers
-with just a change of parameter and get a more unified API for them. We will keep
-the old solvers API for power users but it will be the preferred way to solve
-problems starting from release 1.0.0.
-We provide below some examples of use for the new function and how to
-recover different aspects of the solution (OT plan, full loss, linear part of the
-loss, dual variables) :
-```python
-#Solve  exact ot
-sol = ot.solve(M)
-
-# get the results
-G = sol.plan # OT plan
-ot_loss = sol.value # OT value (full loss for regularized and unbalanced)
-ot_loss_linear = sol.value_linear # OT value for linear term np.sum(sol.plan*M)
-alpha, beta = sol.potentials # dual potentials
-
-# direct plan and loss computation
-G = ot.solve(M).plan
-ot_loss = ot.solve(M).value
-
-# OT exact with marginals a/b
-sol2 = ot.solve(M, a, b)
-
-# regularized and unbalanced OT
-sol_rkl = ot.solve(M, a, b, reg=1) # KL regularization
-sol_rl2 = ot.solve(M, a, b, reg=1, reg_type='L2')
-sol_ul2 = ot.solve(M, a, b, unbalanced=10, unbalanced_type='L2')
-sol_rkl_ukl = ot.solve(M, a, b, reg=10, unbalanced=10) # KL + KL
-
-```
-The function is fully compatible with backends and will be implemented for
-different types of distribution support (empirical distributions, grids) and OT
-problems (Gromov-Wasserstein) in the new releases. This new API is not yet
-presented in the kickstart part of the documentation as there is a small change
-that it might change
-when implementing new solvers but we encourage users to play with it.
-
-Finally, in addition to those many new  this release fixes 20 issues (some long
-standing) and we want to thank all the contributors who made this release so
-big. More details below.
