Stop WordPress sending anything but essential data during the update check.
By default, WordPress sends the following data during the version update check:
<ul>
<li>Current WordPress version</li>
<li>Language</li>
<li>PHP version</li>
<li>MySQL version</li>
<li>If multisite in enabled</li>
<li>Number of websites the WordPress install is running (this will be 1 unless it is a multisite)</li>
<li>Number of users</li>
<li>The WordPress database version during initial installation</li>
</ul>
The WordPress dashboard does not currently provide a way to opt-out of this data collection, but WordPress 4.9 introduced the ability to change whether this data is sent.
This plugin ensures only essential data – current WordPress version and language – are sent during the update check.
There are no options to configure with this plugin.
