@PrefoX as far as I can see:

The importer in v3.1 has not changed at all, the "keep vertex order" option is still there in a tab under "Geometry" foldout.
The exporter in v3.1 effectively always keeps the vertex order -- as if the option was always on. However, it does not keep the face order -- do you need that?

@PrefoX as far as I can see: - The importer in v3.1 has not changed at all, the "keep vertex order" option is still there in a tab under "Geometry" foldout. - The exporter in v3.1 effectively _always_ keeps the vertex order -- as if the option was always on. However, it does not keep the _face_ order -- do you need that?

well everybody is missing the "keep vertex ordner" and the dev told me its always on but not there anymore. its fine if its always on but who would have known that its always on now. the option is still missing but a changelog would have been nice.

Yeah it definitely should have been mentioned in the release notes (and/or updated documentation), but it was not :/

If that option is always "on" and removing it from UI was intentional, we should indeed mention it in manual

That's what I'm trying to figure out (whether the option removal was intentional or not), stay tuned...

"Keep vertex order" is just always on in the new importer/exporter.

The exporter in v3.1 effectively always keeps the vertex order -- as if the option was always on. However, it does not keep the face order -- do you need that?

for Wavefront .obj (Built-In) Blender 3.6.5:
I would need an option for "Keep Face Order".
I made a Script that Exports and ReImports all Objects one after another but I need to save 2 Layers of Color Attributes instead of just one.
Looping through color_attributes.data and save all colors to List and apply them after ReImport does damage my Vertex Colors!
