Remove WordPress version exposure

<?php
/**
 * Remove WordPress Version Exposure
 *
 * WordPress broadcasts its version number in the HTML meta tag, RSS feeds,
 * and script/style query strings. Attackers use this to identify sites
 * running outdated versions with known vulnerabilities. This removes the
 * version from all public-facing outputs. Not a security fix by itself,
 * but reduces information leakage.
 *
 * Usage: Add to functions.php.
 *
 * @category security
 * @language php
