	 * Filters whether to notify the site administrator of a new core update.
	 * By default, administrators are notified when the update offer received
	 * from WordPress.org sets a particular flag. This allows some discretion
	 * in if and when to notify.
	 * This filter is only evaluated once per release. If the same email address
	 * was already notified of the same new version, WordPress won't repeatedly
	 * email the administrator.
	 * This filter is also used on about.php to check if a plugin has disabled
	 * these notifications.
	 * @since 3.7.0
	 * @param bool   $notify Whether the site administrator is notified.
	 * @param object $item   The update offer.
