The NIST IFC File Analyzer now supports IFC4.3\_RC4 in addition to IFC2X3, IFC4, and IFC4.2. Support for other versions of IFC can be added. Google “IFC File Analyzer” to find the website.

@robertlipman we also have a link in the [Software Implementations - buildingSMART Technical](https://technical.buildingsmart.org/resources/software-implementations/). I’ll update the capability listing accordingly.

You should also check out [IFC4.3.0.1 Documentation (buildingsmart.org)](http://ifc43-docs.standards.buildingsmart.org/) for the latest version of the 4.3 spec of the Production Standard
