What replaced asio::tcp::resolver?

I'm currently trying to build a project without any deprecated methods and hit a problem with the resolver. My old code used to look like this:

const asio::ip::tcp::resolver::query query(params.host, std::to_string(params.port));
      m_resolver.async_resolve(query, [&](const std::error_code &ec_, asio::ip::tcp::resolver::iterator iter) {
        if (ec_) {
          ec = ec_;
          return;
        }
        while (iter != asio::ip::tcp::resolver::iterator()) {
          m_socket.reset(new asio::generic::stream_protocol::socket(m_service));
          m_socket->async_connect((*iter++).endpoint(), [&](const std::error_code &err_code) {
            if (err_code) {
              ec = err_code;
              return;
            }
            connected = true;
          });
        };
      });

But now Asio says asio::tcp::resolver::query is deprecated. How is hostname resolution done now?
