  {
      bilingual_str warnings_concise;
      std::vector<bilingual_str> warnings_verbose;

      LOCK(g_warnings_mutex);

      // Pre-release build warning
      if (!CLIENT_VERSION_IS_RELEASE) {
  -        warnings_concise = _("This is a pre-release test build - use at your own risk - do not use for mining or merchant applications");;
