Even if magmi official release is a bit old now, code is under heavy work.
0.7.18 is about to be released and will come with some eagerly awaited enhancements & bugfixes.
I migrated the code to the "updated" sourceforge svn
I also prepared documentation links to be "moved" more easily to the newer sourceforge wiki when they will discontinue hosted mediawiki.
Remote Agent : a way to have magmi executing one one host & targeting a remote magento host , it's an advanced feature that will be detailed in the wiki.
The first version will still need to have DB connectivity between the two hosts but if it has some success , i may extend it to work even with no db connectivity between magmi & remote host.
Mass option remapper utilty: This utility enables to remap option values to another using csv to describe remapping
Category position of item : now you can define the position of item in imported categories or category_ids column.
Multiple category root assignment in the same line is now supported for multistore setups in category importer plugin.
store column is now "autodefaulted" if not present (in some update configs , it may have caused some troubles forcing to set it by value replacer)
