I am pleased to announce our first official WordPress plugin release: SDAC Related Content. This plugin was something I created as I had a need to have a related posts plugin for some VIP clients. The plugin had to not modify any DB tables and it had to use caching.
Version 1 of the plugin was a development version that I used for a few clients. Version 2 added an admin panel under Settings in the WordPress admin. This admin panel allows all kinds of customization.
