Warning: This plugin has not been tested with your current version of WordPress.

It looks as though this plugin has been abandoned until https://github.com/humanmade/WordPress-Importer is complete.

Don’t you love free software: leave users behind out in the cold and start playing with a new toy ??

The issue here is more than a quarter of the Net is running on this free software!

…yeah, it does seem a bit strange that this plugin has been abandoned (if it has).

I’m not even sure if they accept pull requests to fix the current php errors from depreciated functions etc.
