Updating Superset
This file documents any backwards-incompatible changes in Superset and assists people when migrating to a new version.
4.0.0
-
27119: Updates various database columns to use the
MediumText
type, potentially requiring a table lock on MySQL dbs or taking some time to complete on large deployments. -
26450: Deprecates the
KV_STORE
feature flag and its related assets such as the API endpoint andkeyvalue
table. The main dependency of this feature is theSHARE_QUERIES_VIA_KV_STORE
feature flag which allows sharing SQL Lab queries without the necessity of saving the query. Our intention is to use the permalink feature to implement this use case before 5.0 and that's why we are deprecating the feature flag now.
Breaking Changes
- 27130: Fixes the DELETE
/database/{id}/ssh_tunnel/
endpoint to now correctly accept a database ID as a parameter, rather than an SSH tunnel ID. - 27117: Removes the following deprecated endpoints:
/superset/sqllab
,/superset/sqllab/history
,/sqllab/my_queries
use/sqllab
,/sqllab/history
,/savedqueryview/list/?_flt_0_user={get_user_id()}
instead. - 26347: Removes the deprecated
VERSIONED_EXPORT
feature flag. The previous value of the feature flag wasTrue
and now the feature is permanently enabled. - 26328: Removes the deprecated Filter Box code and it's associated dependencies
react-select
andarray-move
. It also removes theDeprecatedSelect
andAsyncSelect
components that were exclusively used by filter boxes. Existing filter boxes will be automatically migrated to native filters. - 26330: Removes the deprecated
DASHBOARD_FILTERS_EXPERIMENTAL
feature flag. The previous value of the feature flag wasFalse
and now the feature is permanently removed. - 26344: Removes the deprecated
ENABLE_EXPLORE_JSON_CSRF_PROTECTION
feature flag. The previous value of the feature flag wasFalse
and now the feature is permanently removed. - 26345: Removes the deprecated
ENABLE_TEMPLATE_REMOVE_FILTERS
feature flag. The previous value of the feature flag wasTrue
and now the feature is permanently enabled. - 26346: Removes the deprecated
REMOVE_SLICE_LEVEL_LABEL_COLORS
feature flag. The previous value of the feature flag wasFalse
and now the feature is permanently removed. - 26348: Removes the deprecated
CLIENT_CACHE
feature flag. The previous value of the feature flag wasFalse
and now the feature is permanently removed. - 26349: Removes the deprecated
DASHBOARD_CACHE
feature flag. The previous value of the feature flag wasFalse
and now the feature is permanently removed. - 26369: Removes the Filter Sets feature including the deprecated
DASHBOARD_NATIVE_FILTERS_SET
feature flag and all related API endpoints. The feature is permanently removed as it was not being actively maintained, it was not widely used, and it was full of bugs. We also considered that if we were to provide a similar feature, it would be better to re-implement it from scratch given the amount of technical debt that the current implementation has. The previous value of the feature flag wasFalse
and now the feature is permanently removed. - 26343: Removes the deprecated
ENABLE_EXPLORE_DRAG_AND_DROP
feature flag. The previous value of the feature flag wasTrue
and now the feature is permanently enabled. - 26331: Removes the deprecated
DISABLE_DATASET_SOURCE_EDIT
feature flag. The previous value of the feature flag wasFalse
and now the feature is permanently removed. - 26636: Sets the
DASHBOARD_VIRTUALIZATION
feature flag toTrue
by default. This feature was introduced by 21438 and will enable virtualization when rendering a dashboard's charts in an attempt to reduce the number of elements (DOM nodes) rendered at once. This is especially useful for large dashboards. - 26637: Sets the
DRILL_BY
feature flag toTrue
by default given that the feature has been tested for a while and reached a stable state. - 26462: Removes the Profile feature given that it's not actively maintained and not widely used.
- 26377: Removes the deprecated Redirect API that supported short URLs used before the permalink feature.
- 26329: Removes the deprecated
DASHBOARD_NATIVE_FILTERS
feature flag. The previous value of the feature flag wasTrue
and now the feature is permanently enabled. - 25510: Reenforces that any newly defined Python data format (other than epoch) must adhere to the ISO 8601 standard (enforced by way of validation at the API and database level) after a previous relaxation to include slashes in addition to dashes. From now on when specifying new columns, dataset owners will need to use a SQL expression instead to convert their string columns of the form %Y/%m/%d etc. to a
DATE
,DATETIME
, etc. type. - 26372: Removes the deprecated
GENERIC_CHART_AXES
feature flag. The previous value of the feature flag wasTrue
and now the feature is permanently enabled.
Potential Downtime
- 26416: Adds two database indexes to the
report_execution_log
table and one database index to thereport_recipient
to improve performance. Scheduled downtime may be required for large deployments.
3.1.0
- 24657: Bumps the cryptography package to augment the OpenSSL security vulnerability.
Other
- 24982: By default, physical datasets on Oracle-like dialects like Snowflake will now use denormalized column names. However, existing datasets won't be affected. To change this behavior, the "Advanced" section on the dataset modal has a "Normalize column names" flag which can be changed to change this behavior.
3.0.3
- 26034: Fixes a problem where numeric x-axes were being treated as categorical values. As a consequence of that, the way labels are displayed might change given that ECharts has a different treatment for numerical and categorical values. To revert to the old behavior, users need to manually convert numerical columns to text so that they are treated as categories. Check https://github.com/apache/superset/issues/26159 for more details.
3.0.0
- 25053: Extends the
ab_user.email
column from 64 to 320 characters which has an associated unique key constraint. This will be problematic for MySQL metadata databases which use the InnoDB storage engine with theinnodb_large_prefix
parameter disabled as the key prefix limit is 767 bytes. Enabling said parameter and ensuring that the table uses either theDYNAMIC
orCOMPRESSED
row format should remedy the problem. See here for more details. - 24911: Changes the column type from
TEXT
toMediumText
in tablelogs
, potentially requiring a table lock on MySQL dbs or taking some time to complete on large deployments. - 24939: Augments the foreign key constraints for the
embedded_dashboards
table to include an explicit CASCADE ON DELETE to ensure the relevant records are deleted when a dashboard is deleted. Scheduled downtime may be advised. - 24938: Augments the foreign key constraints for the
dashboard_slices
table to include an explicit CASCADE ON DELETE to ensure the relevant records are deleted when a dashboard or slice is deleted. Scheduled downtime may be advised. - [24628]https://github.com/apache/superset/pull/24628): Augments the foreign key constraints for the
dashboard_owner
,report_schedule_owner
, andslice_owner
tables to include an explicit CASCADE ON DELETE to ensure the relevant ownership records are deleted when a dataset is deleted. Scheduled downtime may be advised. - 24488: Augments the foreign key constraints for the
sql_metrics
,sqlatable_user
, andtable_columns
tables which reference thetables
table to include an explicit CASCADE ON DELETE to ensure the relevant records are deleted when a dataset is deleted. Scheduled downtime may be advised. - 24232: Enables ENABLE_TEMPLATE_REMOVE_FILTERS, DRILL_TO_DETAIL, DASHBOARD_CROSS_FILTERS by default, marks VERSIONED_EXPORT and ENABLE_TEMPLATE_REMOVE_FILTERS as deprecated.
- 23652: Enables GENERIC_CHART_AXES feature flag by default.
- 23226: Migrated endpoint
/estimate_query_cost/<int:database_id>
to/api/v1/sqllab/estimate/
. Corresponding permissions are can estimate query cost on SQLLab. Make sure you add/replace the necessary permissions on any custom roles you may have. - 23890: Removes Python 3.8 support.
- 24404: FLASK_ENV is getting
deprecated, we recommend using SUPERSET_ENV and reviewing your
config for ENVIRONMENT_TAG_CONFIG, which enables adding a tag in the navbar to
make it more clear which environment your are in.
SUPERSET_ENV=production
andSUPERSET_ENV=development
are the two supported switches based on the default config. - 19242: Adhoc subqueries are now disabled by default for security reasons. To enable them, set the feature flag
ALLOW_ADHOC_SUBQUERY
toTrue
.
Breaking Changes
- [24686]https://github.com/apache/superset/pull/24686): All dataset's custom explore_url are handled as relative URLs on the frontend, behaviour controlled by PREVENT_UNSAFE_DEFAULT_URLS_ON_DATASET.
- 24262: Enabled
TALISMAN_ENABLED
flag by default and provided stricter default Content Security Policy - 24415: Removed the obsolete Druid NoSQL REGEX operator.

,/save_dash/int:dashboard_id/
,/add_slices/int:dashboard_id/
. - 24198 The FAB views
User Registrations
andUser's Statistics
have been changed to Admin only. To re-enable them for non-admin users, please add the following perms to your custom role:menu access on User's Statistics
andmenu access on User Registrations
. - 24354: Removed deprecated APIs
/superset/testconn
,/superset/validate_sql_json/
,/superset/schemas_access_for_file_upload

- 24359: Removed deprecated APIs
/superset/estimate_query_cost/..
,/superset/results/..
,/superset/sql_json/..
,/superset/csv/..
- 24345 Converts
ENABLE_BROAD_ACTIVITY_ACCESS
andMENU_HIDE_USER_INFO
into feature flags and changes the value ofENABLE_BROAD_ACTIVITY_ACCESS
toFalse
as it's more secure. - 24342: Removed deprecated API
/superset/tables/<int:db_id>/<schema>/...
- 24335: Removed deprecated API
/superset/filter/<datasource_type>/<int:datasource_id>/<column>/
- 24333: Removed deprecated API

- 24266 Remove the
ENABLE_ACCESS_REQUEST
config parameter and the associated request/approval workflows. - 24330 Removes

fromExtensionsRegistry
. - 23933 Removes the deprecated Multiple Line Charts.
- 23741 Migrates the TreeMap chart and removes the legacy Treemap code.
- 23712 Migrates the Pivot Table v1 chart to v2 and removes v1 code.
- 24029 Removes the
user
andusername
arguments for theQUERY_LOGGER
andSQL_QUERY_MUTATOR
methods respectively. If the username for the current user is required, thesuperset.utils.core.get_username
method should be used. - 24128 The
RLS_BASE_RELATED_FIELD_FILTERS
config parameter has been removed. Now the Tables dropdown will feature the same tables that the user is able to see elsewhere in the application using the standardDatasourceFilter
, and the Roles dropdown will be filtered using the filter defined inEXTRA_RELATED_QUERY_FILTERS["role"]
. - 23785 Deprecated the following feature flags:
CLIENT_CACHE
,DASHBOARD_CACHE
,DASHBOARD_FILTERS_EXPERIMENTAL
,DASHBOARD_NATIVE_FILTERS
,DASHBOARD_NATIVE_FILTERS_SET
,DISABLE_DATASET_SOURCE_EDIT
,ENABLE_EXPLORE_JSON_CSRF_PROTECTION
,REMOVE_SLICE_LEVEL_LABEL_COLORS
. It also removedDASHBOARD_EDIT_CHART_IN_NEW_TAB
as the feature is supported without the need for a feature flag. - 22801: The Thumbnails feature has been changed to execute as the currently logged in user by default, falling back to the selenium user for anonymous users. To continue always using the selenium user, please add the following to your
superset_config.py
:THUMBNAILS_EXECUTE_AS = ["selenium"]
- 22799: Alerts & Reports has been changed to execute as the owner of the alert/report by default, giving priority to the last modifier and then the creator if either is contained within the list of owners, otherwise the first owner will be used. To continue using the selenium user, please add the following to your
superset_config.py
:ALERT_REPORTS_EXECUTE_AS = ["selenium"]
- 23651: Removes UX_BETA feature flag.
- 23663: Removes deprecated feature flags

2.1.1
- 24185:
/api/v1/database/test_connection
andapi/v1/database/validate_parameters

to/api/v1/chart/<int:id>/data/
. Corresponding permissions arecan slice json on Superset
tocan read on Chart
. Make sure you add/replace the necessary permissions on any custom roles you may have. - 22624: Migrated endpoint
/superset/stop_query/
to/api/v1/query/stop
. Corresponding permissions arecan stop query on Superset
tocan read on Query
. Make sure you add/replace the necessary permissions on any custom roles you may have. - 22579: Migrated endpoint

. Corresponding permissions arecan tables on Superset
tocan read on Database
. Make sure you add/replace the necessary permissions on any custom roles you may have. - 22611: Migrated endpoint
/superset/queries/
toapi/v1/query/updated_since
. Corresponding permissions arecan queries on Superset
tocan read on Query
. Make sure you add/replace the necessary permissions on any custom roles you may have. - 23186: Superset will refuse to start if a default
SECRET_KEY
is detected on a non Flask debug setting. - 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
toTrue
. - 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
inconfig.py
to returnNone
. - 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 toTrue
. 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. - 22798: To make the welcome page more relevant in production environments, the last tab on the welcome page has been changed from to feature all charts/dashboards the user has access to (previously only examples were shown). To keep current behavior unchanged, add the following to your
superset_config.py
:WELCOME_PAGE_LAST_TAB = "examples"
- 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
- 23118: Previously the "database access on " permission granted access to all datasets on the underlying database, but they didn't show up on the list views. Now all dashboards, charts and datasets that are accessible via this permission will also show up on their respective list views.
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
andENABLE_DND_WITH_CLICK_UX
feature flags toTrue
. - 18936: Removes legacy SIP-15 interim logic/flags—specifically the
SIP_15_ENABLED
,SIP_15_GRACE_PERIOD_END
,SIP_15_DEFAULT_TIME_RANGE_ENDPOINTS
, andSIP_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 obsoletetime_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 adatasource_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
andDRUID_METADATA_LINKS_ENABLED
have also been removed. - 19274: The
PUBLIC_ROLE_LIKE_GAMMA
config key has been removed, setPUBLIC_ROLE_LIKE = "Gamma"
to have the same functionality. - 19273: The
SUPERSET_CELERY_WORKERS
andSUPERSET_WORKERS
config keys has been removed. Configure Celery directly usingCELERY_CONFIG
on Superset. - 19231: The
ENABLE_REACT_CRUD_VIEWS
feature flag has been removed (permanently 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 (permanently 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 nowTrue
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 nowTrue
by default, which enables persisting SQL Lab tabs in the backend instead of the browser'slocalStorage
. - 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 anAPP_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 ofAPP_ICON_WIDTH
. - 19017: Removes Python 3.7 support.
- 18970: The
DISABLE_LEGACY_DATASOURCE_EDITOR
feature flag is nowTrue
by default which disables the legacy datasource editor from being shown in the client.
1.5.3
Other
- 22022: HTTP API endpoints
/superset/approve
and/superset/request_access
have been deprecated and their HTTP methods were changed from GET to POST - 21895: Markdown components had their security increased by adhering to the same sanitization process enforced by GitHub.

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
forFILTER_STATE_CACHE_CONFIG
andEXPLORE_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 theFLASK_APP
environment variable (which is set by default when.flaskenv
is loaded). - 15254: The
QUERY_COST_FORMATTERS_BY_ENGINE
,SQL_VALIDATORS_BY_ENGINE
andSCHEDULED_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 todbs.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)
toTEXT
in tabletable_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 theraise_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 isFILTER_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 isEXPLORE_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 usesuperset re-encrypt-secrets
to rotate you current secrets
Potential Downtime
Deprecations
Other
1.4.0
Breaking Changes
- 16660: The
columns
Jinja parameter has been renamedtable_columns
to make thecolumns
query object parameter available in the Jinja context. - 16711: The
url_param
Jinja function will now by default escape the result. For instance, the valueO'Brien
will now be changed toO''Brien
. To disable this behavior, callurl_param
withescape_result
set toFalse

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 thequery
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 config.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 newergraph_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
orgranularity_sqla param
this might take considerable time. - 13052 updates the label in existing pie charts, setting
label_type
frompie_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 theshillelagh
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.

- 12072:
-
11499: Breaking change:
STORE_CACHE_KEYS_IN_METADATA_DB
config flag added (default=False
) to writeCacheKey
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
andrandom
and enforcing static template values. To restore or extend functionality, useJINJA_CONTEXT_ADDONS
andCUSTOM_TEMPLATE_PROCESSORS
insuperset_config.py
. -
11509: Config value
TABLE_NAMES_CACHE_CONFIG
has been renamed toDATA_CACHE_CONFIG
, which will now also hold query results cache from connected datasources (previously held inCACHE_CONFIG
), in addition to the table names. If you will setDATA_CACHE_CONFIG
to a new cache backend different than your previousCACHE_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 theFEATURE_FLAGS
dict insuperset_config.py
. -
11259: config flag ENABLE_REACT_CRUD_VIEWS has been set to
True
by default, set toFalse
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 onFEATURE_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 updatesDashboard.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
, andmarkup
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 directlypip install fbprophet
. -
10320: References to blacklist/whitelist language have been replaced with more appropriate alternatives. All configs referencing containing
WHITE
/BLACK
have been replaced withALLOW
/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-CompressCOMPRESS_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
, andrejected_tables
methods with theraise_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
tocan_access_table
,all_datasource_access
tocan_access_all_datasources
,all_database_access
tocan_access_all_databases
,database_access
tocan_access_database
,schema_access
tocan_access_schema
, anddatasource_access
tocan_access_datasource
. Regrettably it is not viable to provide aliases for the deprecated methods as this would result in a name clash. Finally thecan_access_table
(previouslycan_access_database
) method signature has changed, i.e., the optionalschema
argument no longer exists. -
10030: a change which renames the public security manager
schemas_accessible_by_user
method toget_schemas_accessible_by_user
. -
9786: with the upgrade of
werkzeug
from version0.16.0
to1.0.1
, thewerkzeug.contrib.cache
module has been moved to a standalone package cachelib. For example, to import theRedisCache
class, please use the following import:from cachelib.redis import RedisCache
. -
9794: introduces
create view as
functionality in the sqllab. This change will require thequery
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
, andurl_param
context calls no longer need to be wrapped viacache_key_wrapper
in order to be included in the cache key. Thecache_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 thequery
table which requires locking the table. Given thequery
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 toTIME_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
toFalse
. 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
toTrue
. -
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
andfilter_immune_filter_fields
to favor dashboard scoped filter metadatafilter_scopes
. -
9046: Replaces
can_only_access_owned_queries
byall_query_access
favoring a white list approach. Since a new permission is introduced usesuperset init
to create and associate it by default to theAdmin
role. Note that, by default, all nonAdmin
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 withtables
andab_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 theSecurity
menu, or when editing a table. -
8732: Swagger user interface is now enabled by default. A new permission
show on SwaggerView
is created bysuperset init
and given to theAdmin
Role. To disable the UI, setFAB_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 theDRUID_IS_ACTIVE
configuration variable by setting it toTrue
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. TheSIP_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 ofDEFAULT_HTTP_HEADERS
andOVERRIDE_HTTP_HEADERS
. To retain the same behavior you should useOVERRIDE_HTTP_HEADERS
instead ofHTTP_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
, andclusters.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 commandbabel-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
columns
andtable_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 newflask fab <command>
integrated with Flask cli. -
SUPERSET_UPDATE_PERMS
environment variable was replaced byFAB_UPDATE_PERMS
config boolean key. To disable automatic creation of permissions setFAB_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
orPresto
, we've moved some dependencies that were in the main package as optional now. To get these packages, runpip install superset[presto]
and/orpip install superset[hive]
as required. -
Similarly, if you use Celery's
flower
,gsheetsdb
,thrift
orthrift-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 oldnpm 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
, andg.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 thecelery worker
command, forcing you into crafting your own nativecelery worker
command. Your command should look something likecelery 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 derivativesuperset.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 deriveSupersetSecurityManager
in place of theSecurityManager
-
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 arequirements.txt
with pinned versions if you want to run the suggested versions thatSuperset
builds and runs tests against. Simplypip install -r requirements.txt
in your build pipeline, likely prior topip install superset==0.25.0
