This release includes:

• modifications of the Mmg install tree and CMake build (a clean build and install will be needed). Be careful, the USE_SCOTCH, USE_ELAS and USE_VTK, CMake variables behaves differently than in previous Mmg versions
• the possibility to build Mmg using 64 bit integers to handle larger meshes
• the new -lssurf option to split mesh boundaries along an isovalue while preserving only 1 volume domain
• the new -isoref option to choose the reference of the inserted iso-surface in level-set discretization mode
• the possibility to remove parts of the implicit domain that are not connected to boundary conditions listed in input parameter file
• the possibility to provided non-bijective multi-material maps in level-set discretization mode (at your own risks)
• the preservation of input ridges in level-set discretization mode
• the new -xreg option to smooth position of boundary vertices
• improvement of the gradation process in Mmg3d (-hgrad option)
• support of shared library compilation on windows
• bug fixes.
