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

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).
