A new version (1.7) of the WordPress plugin for displaying Pure Profiles is now available to download at https://bitbucket.org/gmaxwell/pure-wordpress-plugin/downloads
The WordPress pseudo-cron has been removed, meaning that it now updates the cache using a traditional cron job only. This helps prevent any confusion about when the update will take place. In addition, an authentication key (editable on your Settings page) must be sent with the call. This ensures that the API is not being called maliciously.
There are also some other improvements, such as the use of preferred names, and publications linking to DOIs.
