Release Notes for Superset 1.4

Superset 1.4 focuses heavily on continuing to polish the core Superset experience. This release has a very long list of fixes from across the community.

User Facing Features

  • Charts and dashboards in Superset can now be certified! In addition, the Edit Dataset modal more accurately reflects state of Certification (especially for Calculated Columns). (#17335, #16454)

Tab Column

  • Parquet files can now be uploaded into an existing connected database that has Data Upload enabled. Eventually, the contributor hopes that this foundation can be used to accommodate feather and orc files. (#14449)

  • Tabs can now be added to Column elements in dashboards. (#16593)

Tab Column

  • The experience of using alerts and reports have improved in a few minor ways. (#16335,#16281)

Developer Experience

Breaking Changes and Full Changelog

Breaking Changes

  • 16660: The columns Jinja parameter has been renamed table_columns to make the columns query object parameter available in the Jinja context.
  • 16711: The url_param Jinja function will now by default escape the result. For instance, the value O'Brien will now be changed to O''Brien. To disable this behavior, call url_param with escape_result set to False: url_param("my_key", "my default", escape_result=False).
