XML-RPC Update Check

You can query core, plugin, and themes individually, or check all at once.

It defines four new methods:

• xmlrpcCoreUpdateCheck – checks core, returns true/false
• xmlrpcPluginUpdateCheck – checks plugins, returns true/false
• xmlrpcThemeUpdateCheck – checks themes, returns true/false
• xmlrpcUpdatesCheck – checks all of the above, returns an array of trues/falses.

The plugin was created primarily for WPUpCheck (http://trog.qgl.org/wpupcheck/), a simple
Windows application that remotely polls a WordPress site to see if updates are available.
