The "download" link on the plugin page says it's a link to 2.0.4; however, installing that file leaves me with an indication on plugin management page that 2.0has been installed, and a link back to the plugin page, with this familiar language:
There is a new version of Organize Series Plugin available. Download version 2.0.4 here.
Also - the zip file itself is named 2.0.4 -
Nonetheless, looking forward to trying it out.
