Tableau 2025.3 Release: What's New in Pulse, Desktop, Public and more.

There are no big hitters in 2025.3, but it's packed with the small quality-of-life updates that quietly justify Tableau's premium price.

Part ofWhat's new in Tableau 2025.3
  • Tableau Cloud finally gets custom domains, which removes the third-party cookie headache in embedded scenarios and gives users a memorable branded URL.
  • External key management via AWS KMS lets you disable the encryption key and instantly render extracts unreadable to anyone who gains access to your environment.
  • Tableau Prep now supports in-database processing and can write outputs directly back to Databricks, mirroring the earlier Snowflake capability.
  • The release leans heavily on REST API and JWT/unified access tokens for touchless, programmatic site management, SAML configuration and disaster recovery.
  • Viz extensions keep expanding with a new Radial chart, plus workbook-level custom colour palette assignment that can restyle an entire workbook in one step.
