   configuration settings are ``read_timeout`` and ``write_timeout``.
 - Use a different connection pool for read vs. write operations.
   The corresponding settings to configure the maximum pool sizes
   are ``read_pool_size_max`` and ``write_pool_size_max``.

 BREAKING CHANGES
 ----------------
-
 - This release removes the default value for the ``-config.file`` command line
   option, which was ``config.yml``. When the option is omitted, the service
   will use the built-in settings, connecting to CrateDB on ``localhost:5432``.
