If you ever pressed on the "About" menu of our components you will notice some useful information regarding the latest version available, some Release notes and so on.
These info are not coded in the component, these are refreshed from our website.
I want to clarify one point here: The component does nothing more. It's just a XML that is reading from our website to keep you informed about the component. It's not a "home call", nor does the component send any info out. It is just a version checker.
You can check the XML's on our website. the structure is pretty simple
I think this feature is useful for users, especially for security announcements.
for more info take a look at the version_info.php file. Maybe it's an inspiration for other developers.
