## Code

```php
$wpide_strip_core_version = function ( $src ) {
    if ( ! is_string( $src ) || false === strpos( $src, 'ver=' ) ) {
        return $src;
    }

    $query = (string) wp_parse_url( $src, PHP_URL_QUERY );
    parse_str( $query, $args );

    if ( isset( $args['ver'] ) && get_bloginfo( 'version' ) === $args['ver'] ) {
        $src = remove_query_arg( 'ver', $src );
    }

    return $src;
};

add_filter( 'style_loader_src', $wpide_strip_core_version, 9999 );
add_filter( 'script_loader_src', $wpide_strip_core_version, 9999 );
```

## Notes

After a WordPress update, browsers may keep cached core files a little longer.
