Version 2 is a major overhaul of lib3mf. The most important changes compared to versions 1.* are:

autogenerated language bindings for C++, C, Python, Pascal, C#, Golang and NodeJS have been added
(the defunct COM interface has thus been removed)
the handling of properties has been reworked
multiproperties and compositematerials are now supported (finally!)
metadatagroups are now supported
object-level properties are now supported
the documentation of lib3mf is now treated as source-code. It is automatically built and hosted on
https://lib3mf.readthedocs.org/ (WIP)
the Windows binary lib3mf.dll is now digitally signed
deprecated/non-implemented functionality has been removed
performance has been drastically increased when dealing with high numbers of (small) resources and build items
properties of mesh-objects can be cleared
fixed beamlattice representation mesh
encode XML escape characters in the text of nodes
consistently use MAX_MESH_*COUNT and similar
UTF-16 (wchar)-version of all API-calls with strings have been removed: only option is now UTF-8
numerous minor issues have been fixed or improved
