+meshing of OCC models; improved handling of high resolution displays; new
+structured CGNS exporter; new transfinite Beta law; added support for embedded
+curves in HXT; added automatic conversion from partitioned MSH2 files to new
+partitioned entities; element groups can now be imported from UNV files; fixed
