I release a new version of my Drupal  FeedAPI Taxonomy Compare Module.  I found a bug in how the new term was being related to the node.  I was using taxonomy_node_save function from taxonomy.module.  One of the first lines of code in that function is “taxonomy_node_delete_revision($node);” which removes all terms from the node.  Well I was including the current terms in what I was sending this function.  Only the new term.  So the end result was that all of the terms were removed except for the term that was found.  This didn’t effect nodes that didn’t have existing terms.

I also added the ability to match on Synonyms.  So if the tag matched a synonym of a category, then the node is attached to the category term.  This is useful because now you can have more control over what categories you have.  You no longer have to find a place for each term you want to match on.  There is a new setting in admin/settings/feedapi_taxonomy_compare to turn on this functionality.

Download the latest version and let me know.
