## Summary of Changes Add `erase_even_duplicates` parameter to `PMP::repair_polygon_soup()`. If set to `true` and an even number of polygons are duplicates, all duplicates are removed instead of keeping one. This option is useful when transforming a manifold mesh may pinch parts of the mesh and create duplicate faces. Removing duplicates in pairs guarantees that non-manifold edges have an even number of incident faces, which helps restore a consistent mesh structure without creating holes. ## Release Management * Affected package(s): PMP_Mesh_repair * Issue(s) solved (if any): * Feature/Small Feature (if any): [Add_erase_policy_parameter_to_PMP::repair_polygon_soup](https://cgalwiki.geometryfactory.com/CGAL/Members/wiki/Features/Small_Features/Add_erase_policy_parameter_to_PMP::repair_polygon_soup) pre-approved --[Mael Rouxel-Labbé](https://cgalwiki.geometryfactory.com/CGAL/Members/wiki/User:Mael_Rouxel-Labb%C3%A9) 16:36, 2 April 2026 (CEST) * Link to compiled documentation (obligatory for small feature) [*wrong link name to be changed*](httpssss://wrong_URL_to_be_changed/Manual/Pkg) * License and copyright ownership: GF
