Expected rollout start: Monday, May 15th, 2023
Expected final deployment and download available: Tuesday, May 30th, 2023

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.

  • Starting in Looker 23.8, sorting for custom bin fields on the New LookML Runtime sorts by tier number as expected.

  • Starting in Looker 23.8, the Looker IDE will now display an error when incompatible types are compared in Liquid statements.

  • Starting in Looker 23.8, the feature where a row's value could be mapped to different tiers for a custom bin field and the internal sort field generated for it works as expected.

  • Starting in Looker 23.8, the New Explore Visualizations Labs feature is now generally available. The Explore page, Looks, embedded Looks or Explores, and dashboard tile edit windows will display the same style of funnel chart, timeline, single value, and table visualizations as those that appear on dashboard tiles. Additionally, the drill overlay that appears when you drill into an Explore will match the style of the drill overlay that appears in dashboards, instead of the style that appears in Looks.

Access to set_smtp_settings API endpoint

Customers who do not have the oem_jar license feature enabled can now access the set_smtp_settings API endpoint.

Cookieless embed API endpoints

Cookieless embed API endpoints are now marked as stable.

Looker 23.6

Expected rollout start: Monday, April 17th, 2023
Expected final deployment and download available: Thursday, April 27th, 2023

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.

  • Starting in Looker 23.6, the Can Access Legacy Dashboards legacy flag has been removed because legacy dashboards are fully deprecated and removed in this release. Now all legacy dashboards are shown in the new dashboard viewer.

  • Starting in Looker 23.6, you can no longer upgrade dashboards from the Folders page because legacy dashboards have been deprecated.

  • Starting in Looker 23.6, the Liquid parameter tag and _parameter_value variables now return a date string rather than date SQL in non-SQL contexts (for example, the html and link LookML parameters) for date parameters.

  • Starting in Looker 23.6, customer-hosted Looker instances require Git 2.39.1 or later on the host image (see the Installing the Looker application documentation page for the full list of requirements for customer-hosted Looker instances). Git 2.39.1 supports Git worktrees instead of complete Git history clones. Looker uses Git worktrees to provide faster entry into Developer Mode, among other benefits.

Improved performance in add filter

The performance of the add filter to dashboard modal has been improved. A calculation that took ~4s in earlier Looker versions now takes ~4ms (1,000 times faster).

Incremental PDTs for Databricks

Looker supports Incremental PDTs for Databricks

Looker now supports Incremental PDTs for Databricks connections when using Databricks version 12.1 or later.

Customers can now set the position of popup dialogs in an embedded environment

Customers must make changes to their embedded applications to take advantage of this feature. Convenient methods have been added to the Embed SDK, and an updated Embed SDK has been published. The Embed SDK repository has also been updated to provide examples of using this feature with the Embed Javascript (windows postMessage) API.

Looker 23.4

Expected rollout start: Monday, March 13th, 2023
Expected final deployment and download available: Thursday, March 23rd, 2023

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.

  • Starting in Looker 23.4, the Denodo dialect is now deprecated. Customer-hosted instances are expected to update to Denodo 8.

  • Starting in Looker 23.4, YAML LookML projects will return a warning upon project validation. All instances of YAML LookML must be translated to New LookML.

  • Starting in Looker 23.4, the New Users Page and New Groups Page Labs features are now generally available, and admins no longer need to turn the feature flags on. These features add a host of performance improvements to the Users and Groups pages, which includes improved pagination on the Groups page.

Looker Studio Connector and Connected Sheets now available for all Looker-hosted instances

These features were previously available only for instances that were Looker-hosted on Google Cloud

We previously announced the availability for Google Cloud-hosted Looker instances of the Looker Studio connector in Looker 23.0 and Connected Sheets in Looker 22.20. We are excited to announce that both connectors are now available for all Looker-hosted instances, including Looker-hosted on AWS and Azure. Looker users can access and analyze Looker modeled data in Connected Sheets and Looker Studio through the connectors, opening up new enterprise use cases.

Before users can get started with these features, a Looker admin must enable them in the new BI Connectors Admin page.

To learn more, see the Looker documentation for the Looker Studio connector and for Connected Sheets.

New Performant Field Picker Labs feature

Search more quickly and efficiently in large Explore field pickers

The Performant Field Picker Labs feature offers more refined search options, which let users more quickly and efficiently search for fields in large Explore field pickers.

Looker 23.0

Expected final deployment and download available: Tuesday, January 31st, 2023

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.

  • The Legacy Render Card Height legacy feature is now removed.
  • The Use Legacy Internal Query API legacy feature configures Explores, Looks, and SQL Runner to use the legacy API for running queries when enabled. When disabled, Explores, Looks, and SQL Runner use the upgraded internal API for running queries. Upgrading the internal query API does not affect applications using the externally available Looker API. This legacy feature is enabled by default for Looker 23.0 and will be disabled by default starting in Looker 23.2.
  • When the pool_timeout to edit a database connection in an api request is less than the minimum allowed, a pool_timeout error is now thrown.

Expanded Dashboard Theming

New Labs option for embedded dashboard theming

This feature is now enabled by default, and it lets admin users display and hide dashboard header elements on embedded dashboards.

BI Engine Optimizations

This feature is now out of Labs and is generally available

The BI Engine Optimizations feature is enabled for all BigQuery customers who use the BI Engine. With BI Engine optimizations, Looker will generate experimental SQL patterns for certain types of LookML queries that use a BigQuery database connection. These SQL changes are designed specifically to execute faster on Google BigQuery's BI Engine. This feature affects the query runtime and has no effect on query results.

Looker Studio Connector is GA

This feature is now out of Labs and is generally available

The Looker Studio connector lets you access data from a Looker Explore within Looker Studio by adding the Explore as a data source in a Looker Studio report. Enable the Looker Studio BI connector on the BI Connectors page in the Platform section of the Admin menu.

You can also monitor information about the queries that are run by your Looker Studio data sources in the System Activity History Explore.

See the Connect to Looker article in the Looker Studio help center for more information about how to enable the Looker connector in Looker Studio.
