One of the best features of WordPress is the way it lets users check for, download, and install updates for plugins and themes from within the WordPress admin interface. Last year you may recall Jason announced the WordPress Theme Only Attachment and after more work we’re ready to roll out a way for authors to implement automatic updates for their themes in a standard way.
We now have a plugin for WordPress that will show you when a theme you’ve purchased from ThemeForest has an update available. You can then choose to automatically download and install the update. Even better than that though, the plugin will show you all the WordPress themes you’ve purchased on ThemeForest, and allow you to install them too!
We also have a PHP library for authors to include in their WordPress themes that will provide an easy way to implement this functionality within the themes themselves.
