slic3r 1.2.9 and generating AMF files

With the new slicer update a bunch of new things have been added like the 3d viewer. i’m wondering have they gotten rid of the option of creating multi-material AMF files or did they just move it?

I’m seeing the same thing. I’ve looked online and can’t figure out where it’s moved to, or confirmation that it has been removed.

For now I’m opening an older version and using it to create the .amf files and then opening those in 1.2.9 to slice.
