(26 Oct 2014) Fixed an issue with tweets not always being picked up from Twitter due to too many requests for the authentication token, fixed cleanup process not running, added translation to some missed areas, fixed a warning when filtering out old usernames, fixed the conversion of relevant Tweet content that wasn't being correctly turned in to links, updated the AJAX handler to use the recommended method (using admin-ajax.php), updated the Twitter Follow Button to use the new code but also used the IFRAME method to ensure it works with "Prevent Caching", added a Clear Cache button in the Settings, added the ability to filter usernames and hashtags using AND or OR searches, added code to load tweets when caching is turned on but the cache is empty, updated the Tweet object (which holds all tweets) to add some functionality and more clearly define the content and functions, and added logging functionality to log error messages to PHP error log
