Looker 25.4 Release Notes

[sam8]

Looker 25.4 is launching this month! 

📆 Release dates: 

• Expected Looker (original) deployment start: Monday, March 17, 2025

• Expected Looker (original) final deployment and download available: Thursday, March 27, 2025

• Expected Looker (Google Cloud core) deployment start: Monday, March 17, 2025

• Expected Looker (Google Cloud core) final deployment: Monday, March 31, 2025

⚡️ Breaking changes: 

• The gemini_in_looker permission, available only in the Looker Gemini role, is now being enforced at the Looker instance level. This permission is required for any Looker user who will be using Gemini assistance to perform the following tasks:

  • Write LookML

  • Create custom Looker visualizations

  • Query data with Conversational Analytics

• Use of Conversational Analytics in Looker no longer requires Studio in Looker to be enabled for the Looker instance. Gemini in Looker enablement is still required. Admins must disable and then re-enable Gemini in Looker to access Conversational Analytics. 

⭐️ Notable features: 

• By default, Looker connects to your database using the latest version of the JDBC driver for your database dialect. If your selected database dialect has more than one JDBC driver version that is supported by Looker, you can now select an earlier version of the JDBC driver for your dialect. See the Connecting Looker to your database documentation page for more information.

• The Open SQL Interface feature now supports Explores that use the conditionally_filters parameter. Previously disabled Explores are now enabled.

• The Chart Config Editor now supports dynamic annotations. Use the annotationsSource and annotationsTarget parameters to use data from a field as an annotation on a visualization.

• Looker now supports key-pair authentication for Snowflake connections. Note: This feature will be available later in the release cycle (early April 2025).

Check the release notes for more details. Happy Lookering!

Hi! When would the key-pair authentication be available in Looker original? It is the end of April, but it doesn't seem to be available.

Hi visya, the key-pair authentication feature has been delayed. We are hoping to launch it next week.
