+ The native VdmTools file format now has an option to write to a HDF5 file.
+ The CGNSVLib module now allows specification of ADF or HDF5 file type to be used for file export.
VKI releases DevTools 4.3.2 with the following highlights.
+ The Stream and Trace modules are now more tolerant and provide improved user handling of inverted or otherwise degenerate elements.
+ The History module now supports arbitrary section point numbering.
