  - Temporarily disabled some tests to overcome some regressions in
    duckdb.

                 Changes in version 0.4.0 (2021-03-09)                  

  - Added a show_query() method for DataBackendDplyr (#4).
  - A reconnector is automatically added in as_data_backend() for
    objects of type tbl_SQLiteConnection and tbl_duckdb_connection.

                 Changes in version 0.3.0 (2020-12-16)                  

  - New backend DataBackendDuckDB.
  - dplyr is now optional (moved from imports to suggests).

                 Changes in version 0.2.0 (2020-09-28)                  

  - Set a primary key for SQLite databases generated from data frames.
  - Set a reconnector for SQLite databases generated from data frames.
  - Resolved a warning signaled by dplyr-1.0.0.

                 Changes in version 0.1.5 (2020-02-19)                  

  - as_data_backend() method to construct a DataBackendDplyr now
    specialized to operate on objects of type "tbl_lazy" (was "tbl"
    before). This way, local "tbl" objects such as tibbles are converted
    to a DataBackendDataTable by mlr3::as_data_backend.data.frame().

                 Changes in version 0.1.4 (2020-02-05)                  

  - Connections can now be automatically re-connected via a
    user-provided function.
  - DataBackendDplyr now has a finalizer which automatically disconnects
    the database connection during garbage collection.

                 Changes in version 0.1.3 (2019-10-29)                  

  - During construction of DataBackendDplyr, you can now select columns
    to be converted from string to factor. This simplifies the work with
    SQL databases which do not naturally support factors (or where the
    level information is lost in the transaction).

                 Changes in version 0.1.2 (2019-08-26)                  

  - Fixed $distinct() to not return missing values per default.
  - Added na_rm argument to $distinct().
  - Renamed as_sqlite() to as_sqlite_backend()

                 Changes in version 0.1.1 (2019-08-01)
