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.

Great plugin, very well written. Thanks for sharing.

Advanced Automatic Updates adds extra options to WordPress’ built-in Automatic Updates feature. On top of security updates, it also supports installing major releases, plugins, themes, or even regular SVN checkouts!
If you’re working on a WordPress Multisite install, it will properly restrict the options page to your Network Admin.
While this will be useful for the vast majority of sites, please exercise caution, particularly if you have any custom themes or plugins running on your site.

Advanced Automatic Updates
