The morning after releasing version 1.3.0, I woke up with a fix for the nagging issue of drawing count numbers in the right places on contingency graphs. This release fixes that one thing and nothing else.
To use the WordPress version of NarraFirma, first download the zip file (narrafirma-wordpress-plugin-v1.3.1.zip) from the link you see on this page. Then upload the zip file into the plugins section of a running WordPress installation. Caution! Don't mix up the WordPress zip file (narrafirma-wordpress-plugin-v1.3.1.zip) with the source code file (narrafirma.zip).
