Code from the latest commits is at http://drupalcode.org/project/uc_feeds.git/tree/c93a9980fb6f06090cdda871...

It includes these patches:

Before patch #1031700: Stock Levels, your importer mapping settings had lines like the following:

[x-42]	UC: Dimension Units		 Retirer (delete)

When you replace your module with this version, some mappings will disappear, like

[x-42]						 Retirer (delete)

You must manually update those mappings. Add another mapping with "[x-42]" (or whatever fits your case) and you will find "UC: Dimension Units" (or whatever fits your case) in the targets list. After you added this mapping, you should find it at the end. You can remove the original mapping (with the empty target and "[x-42]" (in my example) source) and repeat for every mapping missing its target.
