Potentially breaking changes

Check out these potentially breaking changes; depending on which features or configurations you have implemented, all, some, or none of these changes may apply to your instance.
  • All Looker custom visualizations now use a sandboxed iframe to promote security. Unsandboxed custom visualizations will no longer be supported in the product.
  • The Looker extension framework can be used to create iframes if use_iframes entitlement is added to the extension. Extensions that have the use_embeds entitlement are automatically granted the use_iframes entitlement.
  • The render_tasks API endpoint will no longer support the combination of result_format and dashboard_style and will return a 422 error, unprocessable entity.
  • When the Segment Group action is used, Looker’s payload will no longer include a segment_anonymous_id and will only send the segment_group_id when the segment_group_id LookML tag is present.
  • Looker no longer supports the IBM DB2 Warehouse on Cloud dialect. Instead, for DB2 databases, you can use IBM DB2 on AS400 or IBM DB2 for Linux, UNIX, and Windows (LUW).
  • A syntax warning will now be rendered if the keyword bigquery_datetime_as_timestamp is included in a model.

End of life: Unsandboxed custom visualizations

All Looker custom visualizations now use a sandboxed iframe to promote security.
  • Unsandboxed custom visualizations will no longer be supported in the product.
  • All existing unsandboxed custom visualizations will need to migrate using the Migrate Existing Visualizations option.

New Users Page (Beta) Labs feature

A redesigned user list page is user-friendly and more performant.
  • Supports pagination and has an improved and easier-to-use interface.
  • Provides better performance for customers with large numbers of users, groups, and roles.

Metadata Sidebar is GA

  • Gives modelers insight into how objects (fields, views, and models) are used throughout projects.
  • The sidebar is set to Quick Help by default; users can toggle between Quick Help and metadata at any time.

Potentially breaking changes

Check out these potentially breaking changes; depending on which features or configurations you have implemented, all, some, or none of these changes may apply to your instance.
  • Referencing a measure — such as COUNT, SUM, or AVG — from another view that does not have a primary key declared in a one_to_many join now renders this LookML model error: Field '(?)' depends on '(?)' which cannot be calculated because of a one_to_many or many_to_many join. Consider adding a primary key to '(?)'
  • The List component is now enriched with additional features. Additionally, there are two new components for lists: OrderedList and UnorderedList.
  • The LookML IDE renders the following new warning if the dashboard file declaration is invalid: Invalid dashboard declaration. Dashboard must be declared as: <dashboard_name>.
  • The --scheduler-threads=<i> startup flag can no longer be used to determine alert runs or to disable alerts. For these tasks, use the --alerts-scheduler-threads=<i> flag.
  • The create_query API endpoint now only accepts filter values of type: string.
  • The bigquery_datetime_as_timestamp legacy feature has been removed. Any field with datatype: datetime declared on a model using a BigQuery standard SQL connection will now be treated as a BigQuery datetime type field.
  • Looker Dialect Vertica 6 has been deprecated. Vertica remains a fully supported Looker dialect.
  • Due to several Slack API endpoint deprecations, users must upgrade to Lookerbot version 0.0.16 or later for Lookerbot to function properly.

Looker mobile app is now GA

The Looker mobile app for Android is now available for download on the Google Play Store, and the Looker mobile app for iOS is coming soon.
  • The Looker mobile app includes the new and improved dashboard experience and gives users the ability to report bugs and feedback in-app.
  • The mobile app Labs flag, Mobile App Integration, will be deprecated as of Looker 21.4.
  • All instances on Looker 21.4 or later will have Looker mobile app access enabled by default.

Incremental PDTs

Introducing a new beta Labs feature, Incremental Persistent Derived Tables.
  • Incremental PDTs enable Looker to append fresh data to a PDT instead of rebuilding the entire table.
  • The PDT Activity Dashboard page has been added to the System Activity model and is now accessible from the Persistent Derived Tables page.
  • Supported PDT types include native (LookML), SQL-based, and aggregate tables.
  • Supported dialects include BigQuery standard SQL, MySQL, Postgres, Redshift, Snowflake, Vertica, and Azure Synapse…with more dialects coming soon!

Render Long Tables Labs feature

An experimental Labs feature that changes the rendering behavior of tables on PDFs downloaded from dashboards.

New custom visualization and application on the Looker Marketplace

The Force-Directed Graph visualization and LookML Diagram application let you see the relationships among entities in your data.
  • Force-Directed Graph is a custom visualization. The nodes within the graph are mathematically clustered together based on their relationships with other nodes. The weight of each link (line between nodes) is based on the magnitude of the relationship.
  • With the LookML Diagram application, Looker users with permissions to view or develop LookML can select a model and an Explore to visualize their code in an interactive diagram.

  • The Explore field picker will default to the All Fields tab instead of the In Use tab when an existing query is open.

  • The Revert to Legacy Dashboards legacy feature is disabled by default in 21.0.

  • Developers can now search the Looker Components documentation. The search index also parses page content and page titles.
  • Properties for certain components are available in prop tables. Prop tables are auto-generated from the components interface and are always up to date with the latest release.
