Missing Import/Export file support

[Rockape]

Hi;
Using wings-x64-2.0.1.2016-07-01---16-50.mlab and I notice that the file format support for 3d Studio .3ds is missing from the File > Import/Export functions..?.

I have created a lot of models which are saved out in this file format in previous versions of Wings/Mlab (I prefer Mlab for the Boolean support); that I occasionally need to edit or modify has this support been omitted for a reason?

Thanks.
