Luban 3.8.0 missing feature import and export for project files

Where can I find the the new feature “Feature: Add import and export for project files (# 374)” in Luban 3.8.0?

If you go to the 3D printing, laser engraving, and CNC carving sections in the Snapmaker Luban, you will find open File, Save and Save As options under File. Now you can import and export you project files by using the open and save features.
