Updating Superset

This file documents any backwards-incompatible changes in Superset and assists people when migrating to a new version.

Next Version

  • 7848: If you are running redis with celery, celery bump to 4.3.0 requires redis-py upgrade to 3.2.0 or later.

  • 7667: a change to make all Unix timestamp (which by definition are in UTC) comparisons refer to a timestamp in UTC as opposed to local time.

  • 7653: a change which deprecates the table_columns.database_expression column. Expressions should be handled by the DB engine spec conversion, Python date format, or custom column expression/type.

  • The repo no longer contains translation binaries (.mo) files. If you want translations in your build, you now have to run the command babel-compile --target superset/translations as part of your builds

  • 5451: a change which adds missing non-nullable fields to the datasources table. Depending on the integrity of the data, manual intervention may be required.

  • 5452: a change which adds missing non-nullable fields and uniqueness constraints to the columnsand table_columns tables. Depending on the integrity of the data, manual intervention may be required.

  • fabmanager command line is deprecated since Flask-AppBuilder 2.0.0, use the new flask fab <command> integrated with Flask cli.

  • SUPERSET_UPDATE_PERMS environment variable was replaced by FAB_UPDATE_PERMS config boolean key. To disable automatic creation of permissions set FAB_UPDATE_PERMS = False on config.

  • 5453: a change which adds missing non-nullable fields and uniqueness constraints to the metrics and sql_metrics tables. Depending on the integrity of the data, manual intervention may be required.

  • 7616: this bug fix changes time_compare deltas to correctly evaluate to the number of days prior instead of number of days in the future. It will change the data for advanced analytics time_compare so 1 year from 5/1/2019 will be calculated as 365 days instead of 366 days.

Superset 0.32.0

  • npm run backend-sync is deprecated and no longer needed, will fail if called
  • 5445: a change which prevents encoding of empty string from form data in the database. This involves a non-schema changing migration which does potentially impact a large number of records. Scheduled downtime may be advised.

Superset 0.31.0

  • If you use Hive or Presto, we've moved some dependencies that were in the main package as optional now. To get these packages, run pip install superset[presto] and/or pip install superset[hive] as required.

  • Similarly, if you use Celery's flower, gsheetsdb, thrift or thrift-sasl, those dependencies have now been made optional in our package, meaning you may have to install them in your environment post 0.31.0

  • boto3 / botocore was removed from the dependency list. If you use s3 as a place to store your SQL Lab result set or Hive uploads, you may have to rely on an alternate requirements.txt file to install those dependencies.

  • From 0.31.0 onwards, we recommend not using the npm package yarn in favor of good old npm install. While yarn should still work just fine, you should probably align to guarantee builds similar to the ones we use in testing and across the community in general.

Superset 0.30.0

  • 0.30.0 includes a db_migration that removes allow_run_sync. This may require downtime because during the migration if the db is migrated first, superset will get 500 errors when the code can't find the field (until the deploy finishes).

Superset 0.29.0

  • India was removed from the "Country Map" visualization as the geojson file included in the package was very large

Superset 0.28.0

  • Support for Python 2 is deprecated, we only support >=3.6 from 0.28.0 onwards

  • Superset 0.28 deprecates the previous dashboard layout. While 0.27 offered a migration workflow to users and allowed them to validate and publish their migrated dashboards individually, 0.28 forces the migration of all dashboards through an automated db migration script. We do recommend that you take a backup prior to this migration.

  • Superset 0.28 deprecates the median cluster label aggregator for mapbox visualizations. This particular aggregation is not supported on mapbox visualizations going forward.

  • Superset 0.28 upgrades flask-login to >=0.3, which includes a backwards-incompatible change: g.user.is_authenticated, g.user.is_anonymous, and g.user.is_active are now properties instead of methods.

Superset 0.27.0

  • Superset 0.27 start to use nested layout for dashboard builder, which is not backward-compatible with earlier dashboard grid data. We provide migration script to automatically convert dashboard grid to nested layout data. To be safe, please take a database backup prior to this upgrade. It's the only way people could go back to a previous state.

Superset 0.26.0

  • Superset 0.26.0 deprecates the superset worker CLI, which is a simple wrapper around the celery worker command, forcing you into crafting your own native celery worker command. Your command should look something like celery worker --app=superset.sql_lab:celery_app --pool=gevent -Ofair

Superset 0.25.0

Superset 0.25.0 contains a backwards incompatible changes. If you run a production system you should schedule downtime for this upgrade.

The PRs bellow have more information around the breaking changes:

  • 4587 : a backward incompatible database migration that requires downtime. Once the db migration succeeds, the web server needs to be restarted with the new version. The previous version will fail
  • 4565 : we've changed the security model a bit where in the past you would have to define your authentication scheme by inheriting from Flask App Builder's from flask_appbuilder.security.sqla.manager import SecurityManager, you now have to derive Superset's own derivative superset.security.SupersetSecurityManager. This can provide you with more hooks to define your own logic and/or defer permissions to another system as needed. For all implementation, you simply have to import and derive SupersetSecurityManager in place of the SecurityManager
  • 4835 : our setup.py now only pins versions where required, giving you more latitude in using versions of libraries as needed. We do now provide a requirements.txt with pinned versions if you want to run the suggested versions that Superset builds and runs tests against. Simply pip install -r requirements.txt in your build pipeline, likely prior to pip install superset==0.25.0
