Oct 1, 2026: Snowflake Data Clean Rooms updates

Clean Rooms API Version: 18.6

The following updates are now available in Snowflake Data Clean Rooms:

  • Faster setup and iteration for same-organization collaborations: When every collaborator in a collaboration belongs to the same organization, Snowflake skips the automated security scan. The collaboration and its updates become available sooner, which makes a same-org collaboration a much faster environment for developing and testing code specs before you share your work outside your organization. To override this behavior, set the new optional distribution: external field in that collaboration’s specification. Cross-organization collaborations always have to pass the security scan before they can be used. For more information, see iterating quickly in a same-organization collaboration.
  • Clean room creation disabled in the legacy web application: As part of the ongoing deprecation of the legacy Data Clean Rooms web application, you can no longer create new clean rooms through the legacy web interface. Existing legacy clean rooms aren’t affected, and the clean room list page now shows a banner with the remaining retirement dates. For the full timeline and migration guidance, see End of life for legacy Provider and Consumer Data Clean Rooms.
  • General performance improvements and bug fixes.
  • Updates to private preview features.
