Updating Superset

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

Next

  • 22022: HTTP API endpoints /superset/approve and /superset/request_access have been deprecated and their HTTP methods were changed from GET to POST
  • 20606: When user clicks on chart title or "Edit chart" button in Dashboard page, Explore opens in the same tab. Clicking while holding cmd/ctrl opens Explore in a new tab. To bring back the old behaviour (always opening Explore in a new tab), flip feature flag DASHBOARD_EDIT_CHART_IN_NEW_TAB to True.
  • 20799: Presto and Trino engine will now display tracking URL for running queries in SQL Lab. If for some reason you don't want to show the tracking URL (for example, when your data warehouse hasn't enabled access for to Presto or Trino UI), update TRACKING_URL_TRANSFORMER in config.py to return None.
  • 21002: Support Python 3.10 and bump pandas 1.4 and pyarrow 6.
  • 21163: The time grain will be decoupled from the time filter column and the time grain control will move below the X-Axis control when GENERIC_CHART_AXES feature flags set to True. The time grain will be applied on the time column in the column-like controls(x axis, dimensions) instead of the time column in the time section.
  • 21284: The non-functional MAX_TABLE_NAMES config key has been removed.
  • 21794: Deprecates the undocumented PRESTO_SPLIT_VIEWS_FROM_TABLES feature flag. Now for Presto, like other engines, only physical tables are treated as tables.

Breaking Changes

  • 22328: For deployments that have enabled the "THUMBNAILS" feature flag, the function that calculates dashboard digests has been updated to consider additional properties to more accurately identify changes in the dashboard metadata. This change will invalidate all currently cached dashboard thumbnails.
  • 21765: For deployments that have enabled the "ALERT_REPORTS" feature flag, Gamma users will no longer have read and write access to Alerts & Reports by default. To give Gamma users the ability to schedule reports from the Dashboard and Explore view like before, create an additional role with "can read on ReportSchedule" and "can write on ReportSchedule" permissions. To further give Gamma users access to the "Alerts & Reports" menu and CRUD view, add "menu access on Manage" and "menu access on Alerts & Report" permissions to the role.

Potential Downtime

  • 21284: A change which drops the unused dbs.allow_multi_schema_metadata_fetch column via a (potentially locking) DDL operation.

Other

2.0.1

  • 21895: Markdown components had their security increased by adhering to the same sanitization process enforced by Github. This means that some HTML elements found in markdowns are not allowed anymore due to the security risks they impose. If you're deploying Superset in a trusted environment and wish to use some of the blocked elements, then you can use the HTML_SANITIZATION_SCHEMA_EXTENSIONS configuration to extend the default sanitization schema. There's also the option to disable HTML sanitization using the HTML_SANITIZATION configuration but we do not recommend this approach because of the security risks. Given the provided configurations, we don't view the improved sanitization as a breaking change but as a security patch.

Breaking Changes

Potential Downtime

Other

2.0.0

  • 19046: Enables the drag and drop interface in Explore control panel by default. Flips ENABLE_EXPLORE_DRAG_AND_DROP and ENABLE_DND_WITH_CLICK_UX feature flags to True.
  • 18936: Removes legacy SIP-15 interim logic/flags—specifically the SIP_15_ENABLED, SIP_15_GRACE_PERIOD_END, SIP_15_DEFAULT_TIME_RANGE_ENDPOINTS, and SIP_15_TOAST_MESSAGE flags. Time range endpoints are no longer configurable and strictly adhere to the [start, end) paradigm, i.e., inclusive of the start and exclusive of the end. Additionally this change removes the now obsolete time_range_endpoints from the form-data and resulting in the cache being busted.
  • 19570: makes sqloxide optional so the SIP-68 migration can be run on aarch64. If the migration is taking too long installing sqloxide manually should improve the performance.
  • 20170: Introduced a new endpoint for getting datasets samples.

Breaking Changes

  • 19981: Per SIP-81 the /explore/form_data api now requires a datasource_type in addition to a datasource_id for POST and PUT requests
  • 19770: Per SIP-11 and SIP-68, the native NoSQL Druid connector is deprecated and has been removed. Druid is still supported through SQLAlchemy via pydruid. The config keys DRUID_IS_ACTIVE and DRUID_METADATA_LINKS_ENABLED have also been removed.
  • 19274: The PUBLIC_ROLE_LIKE_GAMMA config key has been removed, set PUBLIC_ROLE_LIKE = "Gamma" to have the same functionality.
  • 19273: The SUPERSET_CELERY_WORKERS and SUPERSET_WORKERS config keys has been removed. Configure Celery directly using CELERY_CONFIG on Superset.
  • 19231: The ENABLE_REACT_CRUD_VIEWS feature flag has been removed (premantly enabled). Any deployments which had set this flag to false will need to verify that the React views support their use case.
  • 19230: The ROW_LEVEL_SECURITY feature flag has been removed (permantly enabled). Any deployments which had set this flag to false will need to verify that the presence of the Row Level Security feature does not interfere with their use case.
  • 19168: Celery upgrade to 5.X resulted in breaking changes to its command line invocation. Please follow these instructions for adjustments. Also consider migrating you Celery config per here.
  • 19142: The VERSIONED_EXPORT config key is now True by default.
  • 19113: The ENABLE_JAVASCRIPT_CONTROLS config key has moved from an app config to a feature flag. Any deployments who overrode this setting will now need to override the feature flag from here onward.
  • 19107: The SQLLAB_BACKEND_PERSISTENCE feature flag is now True by default, which enables persisting SQL Lab tabs in the backend instead of the browser's localStorage.
  • 19083: Updates the mutator function in the config file to take a SQL argument and a list of kwargs. Any SQL_QUERY_MUTATOR config function overrides will need to be updated to match the new set of params. It is advised regardless of the dictionary args that you list in your function arguments, to keep **kwargs as the last argument to allow for any new kwargs to be passed in.
  • 19049: The APP_ICON_WIDTH config key has been removed. Superset should now be able to handle different logo sizes without having to explicitly set an APP_ICON_WIDTH. This might affect the size of existing custom logos as the UI will now resize them according to the specified space of maximum 148px and not according to the value of APP_ICON_WIDTH.
  • 19017: Removes Python 3.7 support.
  • 18970: The DISABLE_LEGACY_DATASOURCE_EDITOR feature flag is now True by default which disables the legacy datasource editor from being shown in the client.

1.5.2

Other

  • 19570: makes sqloxide optional so the SIP-68 migration can be run on aarch64. If the migration is taking too long installing sqloxide manually should improve the performance.

1.5.0

Breaking Changes

  • 18976: When running the app in debug mode, the app will default to use SimpleCache for FILTER_STATE_CACHE_CONFIG and EXPLORE_FORM_DATA_CACHE_CONFIG. When running in non-debug mode, a cache backend will need to be defined, otherwise the application will fail to start. For installations using Redis or other caching backends, it is recommended to use the same backend for both cache configs.
  • 17881: Previously simple adhoc filter values on string columns were stripped of enclosing single and double quotes. To fully support literal quotes in filters, both single and double quotes will no longer be removed from filter values.
  • 17556: Bumps mysqlclient from v1 to v2.
  • 17539: All Superset CLI commands, e.g. init, load_examples, etc. require setting the FLASK_APP environment variable (which is set by default when .flaskenv is loaded).
  • 15254: The QUERY_COST_FORMATTERS_BY_ENGINE, SQL_VALIDATORS_BY_ENGINE and SCHEDULED_QUERIES feature flags are now defined as config keys given that feature flags are reserved for boolean only values.

Potential Downtime

  • 16756: a change which renames the dbs.allow_csv_upload column to dbs.allow_file_upload via a (potentially locking) DDL operation.
  • 17539: all Superset CLI commands (init, load_examples and etc) require setting the FLASK_APP environment variable (which is set by default when .flaskenv is loaded)
  • 17360: changes the column type from VARCHAR(32) to TEXT in table table_columns, potentially requiring a table lock on MySQL dbs or taking some time to complete on large deployments.
  • 17543: introduces new models from SIP-68. The database migration migrates the old models (SqlaTable, TableColumn, SqlMetric) to the new models (Column, Table, Dataset), and the PR introduces logic to keep the old models in sync with the new ones until they are fully removed. The migration might take considerable time depending on the number of datasets.

Deprecations

  • 18960: Persisting URL params in chart metadata is no longer supported. To set a default value for URL params in Jinja code, use the optional second argument: url_param("my-param", "my-default-value").

Other

  • 17589: It is now possible to limit access to users' recent activity data by setting the ENABLE_BROAD_ACTIVITY_ACCESS config flag to false, or customizing the raise_for_user_activity_access method in the security manager.
  • 17536: introduced a key-value endpoint to store dashboard filter state. This endpoint is backed by Flask-Caching and the default configuration assumes that the values will be stored in the file system. If you are already using another cache backend like Redis or Memcached, you'll probably want to change this setting in superset_config.py. The key is FILTER_STATE_CACHE_CONFIG and the available settings can be found in Flask-Caching docs.
  • 17882: introduced a key-value endpoint to store Explore form data. This endpoint is backed by Flask-Caching and the default configuration assumes that the values will be stored in the file system. If you are already using another cache backend like Redis or Memcached, you'll probably want to change this setting in superset_config.py. The key is EXPLORE_FORM_DATA_CACHE_CONFIG and the available settings can be found in Flask-Caching docs.

1.4.1

Breaking Changes

  • 17984: Default Flask SECRET_KEY has changed for security reasons. You should always override with your own secret. Set PREVIOUS_SECRET_KEY (ex: PREVIOUS_SECRET_KEY = "\2\1thisismyscretkey\1\2\e\y\y\h") with your previous key and use superset re-encrypt-secrets to rotate you current secrets

Potential Downtime

Deprecations

Other

1.4.0

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).

Potential Downtime

Deprecations

Other

  • 16809: When building the superset frontend assets manually, you should now use Node 16 (previously Node 14 was required/recommended). Node 14 will most likely still work for at least some time, but is no longer actively tested for on CI.

1.3.0

Breaking Changes

  • 15909: a change which drops a uniqueness criterion (which may or may not have existed) to the tables table. This constraint was obsolete as it is handled by the ORM due to differences in how MySQL, PostgreSQL, etc. handle uniqueness for NULL values.

Potential Downtime

  • 14234: Adds the limiting_factor column to the query table. Give the migration includes a DDL operation on a heavily trafficked table, potential service downtime may be required.

-16454: Adds the extra column to the table_columns table. Users using MySQL will either need to schedule downtime or use the percona toolkit (or similar) to perform the migration.

1.2.0

Deprecations

  • 13440: Dashboard/Charts reports and old Alerts is deprecated. The following config keys are deprecated:
    • ENABLE_ALERTS
    • SCHEDULED_EMAIL_DEBUG_MODE
    • EMAIL_REPORTS_CRON_RESOLUTION
    • EMAIL_ASYNC_TIME_LIMIT_SEC
    • EMAIL_REPORT_BCC_ADDRESS
    • EMAIL_REPORTS_USER

Other

  • 13772: Row level security (RLS) is now enabled by default. To activate the feature, please run superset init to expose the RLS menus to Admin users.
  • 13980: Data health checks no longer use the metadata database as an interim cache. Though non-breaking, deployments which implement complex logic should likely memoize the callback function. Refer to documentation in the confg.py file for more detail.
  • 14255: The default CSV_TO_HIVE_UPLOAD_DIRECTORY_FUNC callable logic has been updated to leverage the specified database and schema to ensure the upload S3 key prefix is unique. Previously tables generated via upload from CSV with the same name but differ schema and/or cluster would use the same S3 key prefix. Note this change does not impact previously imported tables.

1.1.0

Breaking Changes

  • This is the first release since we adopted semantic versioning (SIP-57). There are no breaking changes in 1.1.0 since this is a minor release.

Potential Downtime

  • 13111 has a database migration that replaces directed_force charts with newer graph_chart charts based on Apache ECharts.
  • 13216 adds a UUID column to models that are missing it. The original migration script that added the column would incorrectly complete when the column couldn't be added, resulting in a broken schema. The script is optimized for MySQL and Postgres, so depending on the database and the number of objects this migration might take considerable time.
  • 12960 populates the granularity parameter in existing charts. Depending on the number of charts without a granularity or granularity_sqla param this might take considerable time.
  • 13052 updates the label in existing pie charts, setting label_type from pie_label_type. Depending on the number of pie charts this might take considerable time.
  • 12680 creates a new table, dashboard_roles, for role based dashboard level access.
  • 12552 updates charts that have the time range defined using "until" and "since". Depending on the number of charts this might take considerable time.

Deprecations

  • 12552 removes the use of unclear time offsets, eg, "30 days". An error message is displayed if the user doesn't specify "ago" or "later", instructing the user of the correct format.
  • 12627 deprecates the legacy alerts module.

Other

  • shillelagh is now the recommended module to connect Superset to Google Spreadsheets since it's more robust and has extensive test coverage. You should uninstall the gsheetsdb module and install the shillelagh module in its place. Shillelagh is a drop-in replacement, so no modifications are needed to be done on existing queries, datasets, or charts.

1.0.0

Breaking Changes

  • 11509: Dataset metadata updates check user ownership, only owners or an Admin are allowed.

  • Security simplification (SIP-19), the following permission domains were simplified:

    • 12072: Query with can_read, can_write
    • 12036: Database with can_read, can_write.
    • 12012: Dashboard with can_read, can_write.
    • 12061: Log with can_read, can_write.
    • 12000: Dataset with can_read, can_write.
    • 12014: Annotation with can_read, can_write.
    • 11981: Chart with can_read, can_write.
    • 11853: ReportSchedule with can_read, can_write.
    • 11856: CssTemplate with can_read, can_write.
    • 11764: SavedQuery with can_read, can_write. Old permissions will be automatically migrated to these new permissions and applied to all existing security Roles.

  • 11499: Breaking change: STORE_CACHE_KEYS_IN_METADATA_DB config flag added (default=False) to write CacheKey records to the metadata DB. CacheKey recording was enabled by default previously.

  • 11704 Breaking change: Jinja templating for SQL queries has been updated, removing default modules such as datetime and random and enforcing static template values. To restore or extend functionality, use JINJA_CONTEXT_ADDONS and CUSTOM_TEMPLATE_PROCESSORS in superset_config.py.

  • 11509: Config value TABLE_NAMES_CACHE_CONFIG has been renamed to DATA_CACHE_CONFIG, which will now also hold query results cache from connected datasources (previously held in CACHE_CONFIG), in addition to the table names. If you will set DATA_CACHE_CONFIG to a new cache backend different than your previous CACHE_CONFIG, plan for additional cache warmup to avoid degrading charting performance for the end users.

  • 11575 The Row Level Security (RLS) config flag has been moved to a feature flag. To migrate, add ROW_LEVEL_SECURITY: True to the FEATURE_FLAGS dict in superset_config.py.

  • 11259: config flag ENABLE_REACT_CRUD_VIEWS has been set to True by default, set to False if you prefer to the vintage look and feel. However, we may discontinue support on the vintage list view in the future.

  • 11244: The REDUCE_DASHBOARD_BOOTSTRAP_PAYLOAD feature flag has been removed after being set to True for multiple months.

  • 11172: Turning off language selectors by default as i18n is incomplete in most languages and requires more work. You can easily turn on the languages you want to expose in your environment in superset_config.py

  • 11172: Breaking change: SQL templating is turned off by default. To turn it on set ENABLE_TEMPLATE_PROCESSING to True on FEATURE_FLAGS

Potential Downtime

  • 11920: Undoes the DB migration from 11714 to prevent adding new columns to the logs table. Deploying a sha between these two PRs may result in locking your DB.

  • 11714: Logs significantly more analytics events (roughly double?), and when using DBEventLogger (default) could result in stressing the metadata database more.

  • 11098: includes a database migration that adds a uuid column to most models, and updates Dashboard.position_json to include chart UUIDs. Depending on number of objects, the migration may take up to 5 minutes, requiring planning for downtime.

Deprecations

  • 11155: The FAB_UPDATE_PERMS config parameter is no longer required as the Superset application correctly informs FAB under which context permissions should be updated.

0.38.0

  • 10887: Breaking change: The custom cache backend changed in order to support the Flask-Caching factory method approach and thus must be registered as a custom type. See here for specifics.

  • 10674: Breaking change: PUBLIC_ROLE_LIKE_GAMMA was removed is favour of the new PUBLIC_ROLE_LIKE so it can be set to whatever role you want.

  • 10590: Breaking change: this PR will convert iframe chart into dashboard markdown component, and remove all iframe, separator, and markup slices (and support) from Superset. If you have important data in those slices, please backup manually.

  • 10562: EMAIL_REPORTS_WEBDRIVER is deprecated use WEBDRIVER_TYPE instead.

  • 10567: Default WEBDRIVER_OPTION_ARGS are Chrome-specific. If you're using FF, should be --headless only

  • 10241: change on Alpha role, users started to have access to "Annotation Layers", "Css Templates" and "Import Dashboards".

  • 10324: Facebook Prophet has been introduced as an optional dependency to add support for timeseries forecasting in the chart data API. To enable this feature, install Superset with the optional dependency prophet or directly pip install fbprophet.

  • 10320: References to blacklist/whitelist language have been replaced with more appropriate alternatives. All configs referencing containing WHITE/BLACK have been replaced with ALLOW/DENY. Affected config variables that need to be updated: TIME_GRAIN_BLACKLIST, VIZ_TYPE_BLACKLIST, DRUID_DATA_SOURCE_BLACKLIST.

0.37.1

  • 10794: Breaking change: uuid python package is not supported on Jinja2 anymore, only uuid functions are exposed eg: uuid1, uuid3, uuid4, uuid5.

0.37.0

  • 9964: Breaking change on Flask-AppBuilder 3. If you're using OAuth, find out what needs to be changed here.

  • 10233: a change which deprecates the ENABLE_FLASK_COMPRESS config option in favor of the Flask-Compress COMPRESS_REGISTER config option which serves the same purpose.

  • 10222: a change which changes how payloads are cached. Previous cached objects cannot be decoded and thus will be reloaded from source.

  • 10130: a change which deprecates the dbs.perm column in favor of SQLAlchemy hybrid attributes.

  • 10034: a change which deprecates the public security manager assert_datasource_permission, assert_query_context_permission, assert_viz_permission, and rejected_tables methods with the raise_for_access method which also handles assertion logic for SQL tables.

  • 10031: a change which renames the following public security manager methods: can_access_datasource to can_access_table, all_datasource_access to can_access_all_datasources, all_database_access to can_access_all_databases, database_access to can_access_database, schema_access to can_access_schema, and datasource_access to can_access_datasource. Regrettably it is not viable to provide aliases for the deprecated methods as this would result in a name clash. Finally the can_access_table (previously can_access_database) method signature has changed, i.e., the optional schema argument no longer exists.

  • 10030: a change which renames the public security manager schemas_accessible_by_user method to get_schemas_accessible_by_user.

  • 9786: with the upgrade of werkzeug from version 0.16.0 to 1.0.1, the werkzeug.contrib.cache module has been moved to a standalone package cachelib. For example, to import the RedisCache class, please use the following import: from cachelib.redis import RedisCache.

  • 9794: introduces create view as functionality in the sqllab. This change will require the query table migration and potential service downtime as that table has quite some traffic.

  • 9572: a change which by default means that the Jinja current_user_id, current_username, and url_param context calls no longer need to be wrapped via cache_key_wrapper in order to be included in the cache key. The cache_key_wrapper function should only be required for Jinja add-ons.

0.36.0

  • 8867: a change which adds the tmp_schema_name column to the query table which requires locking the table. Given the query table is heavily used performance may be degraded during the migration. Scheduled downtime may be advised.

  • 9238: the config option TIME_GRAIN_FUNCTIONS has been renamed to TIME_GRAIN_EXPRESSIONS to better reflect the content of the dictionary.

  • 9218: SQLite connections have been disabled by default for analytics databases. You can optionally enable SQLite by setting PREVENT_UNSAFE_DB_CONNECTIONS to False. It is not recommended to change this setting, as arbitrary SQLite connections can lead to security vulnerabilities.

  • 9133: Security list of permissions and list views has been disable by default. You can optionally enable them back again by setting the following config keys: FAB_ADD_SECURITY_PERMISSION_VIEW, FAB_ADD_SECURITY_VIEW_MENU_VIEW, FAB_ADD_SECURITY_PERMISSION_VIEWS_VIEW to True.

  • 9173: Changes the encoding of the query source from an int to an enum.

  • 9120: Changes the default behavior of ad-hoc sharing of queries in SQLLab to one that links to the saved query rather than one that copies the query data into the KVStore model and links to the record there. This is a security-related change that makes SQLLab query sharing respect the existing role-based access controls. Should you wish to retain the existing behavior, set two feature flags: "KV_STORE": True will re-enable the /kv/ and /kv/store/ endpoints, and "SHARE_QUERIES_VIA_KV_STORE": True will tell the front-end to utilize them for query sharing.

  • 9109: Expire filter_immune_slices and filter_immune_filter_fields to favor dashboard scoped filter metadata filter_scopes.

  • 9046: Replaces can_only_access_owned_queries by all_query_access favoring a white list approach. Since a new permission is introduced use superset init to create and associate it by default to the Admin role. Note that, by default, all non Admin users will not be able to access queries they do not own.

  • 8901: The datasource's update timestamp has been added to the query object's cache key to ensure updates to datasources are always reflected in associated query results. As a consequence all previously cached results will be invalidated when updating to the next version.

  • 8699: A row_level_security_filters table has been added, which is many-to-many with tables and ab_roles. The applicable filters are added to the sqla query, and the RLS ids are added to the query cache keys. If RLS is enabled in config.py (ENABLE_ROW_LEVEL_SECURITY = True; by default, it is disabled), they can be accessed through the Security menu, or when editing a table.

  • 8732: Swagger user interface is now enabled by default. A new permission show on SwaggerView is created by superset init and given to the Admin Role. To disable the UI, set FAB_API_SWAGGER_UI = False on config.

  • 8721: When using the cache warmup Celery task you should now specify the SUPERSET_WEBSERVER_PROTOCOL variable in your configuration (probably either "http" or "https"). This defaults to "http".

  • 8512: DRUID_IS_ACTIVE now defaults to False. To enable Druid-API-based functionality, override the DRUID_IS_ACTIVE configuration variable by setting it to True for your deployment.

  • 8450: The time range picker now uses UTC for the tooltips and default placeholder timestamps (sans timezone).

  • 8418: FLASK_APP / Worker App have changed. FLASK_APP should be updated to superset.app:create_app() and Celery Workers should be started with --app=superset.tasks.celery_app:app

  • 9017: SIP_15_ENABLED now defaults to True which ensures that for all new SQL charts the time filter will behave like [start, end). Existing deployments should either disable this feature to keep the status quo or inform their users of this change prior to enabling the flag. The SIP_15_GRACE_PERIOD_END option provides a mechanism for specifying how long chart owners have to migrate their charts (the default is indefinite).

0.35.0

  • 8370: Deprecates the HTTP_HEADERS variable in favor of DEFAULT_HTTP_HEADERS and OVERRIDE_HTTP_HEADERS. To retain the same behavior you should use OVERRIDE_HTTP_HEADERS instead of HTTP_HEADERS. HTTP_HEADERS will still work but may be removed in a future update.

  • We're deprecating the concept of "restricted metric", this feature was not fully working anyhow.

  • 8117: If you are using ENABLE_PROXY_FIX = True, review the newly-introduced variable, PROXY_FIX_CONFIG, which changes the proxy behavior in accordance with Werkzeug

  • 8069: introduces MessagePack and PyArrow for async query results backend serialization. To disable set RESULTS_BACKEND_USE_MSGPACK = False in your configuration.

  • 8371: makes tables.table_name, dbs.database_name, datasources.cluster_name, and clusters.cluster_name non-nullable. Depending on the integrity of the data, manual intervention may be required.

0.34.0

  • 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 (which may be case insensitive depending on your database configuration) 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 (which may be case insensitive depending on your database configuration) 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

  • 5933/6078: changes which add schema and table metadata cache timeout logic at the database level. If left undefined caching of metadata is disabled.

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 below have more information around the breaking changes:

  • 9825: Support for Excel sheet upload added. To enable support, install Superset with the optional dependency excel

  • 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
