 ## 0.9.3
 
+#### New features
++ `ot.gromov._gw.solve_gromov_linesearch` now has an argument to specifify if the matrices are symmetric in which case the computation can be done faster.
+
 #### Closed issues
 - Fixed an issue with cost correction for mismatched labels in `ot.da.BaseTransport` fit methods. This fix addresses the original issue introduced PR #587 (PR #593)
 - Fix gpu compatibility of sr(F)GW solvers when `G0 is not None`(PR #596)
