List of changes

Important

This change list has been compiled using reasonable efforts. We are not always able to determine the full customer impact of a behavior change beforehand. The change list may not include all changes in a release, for example, last minute or emergency changes. In addition, behavior changes that are determined to have minimal to no user impact may not be pre-announced.

If you have any questions about the changes in this bundle, please contact Snowflake Support.

For differences between the in-advance and final versions of these notes, see Behavior Change Bundle change log.

For information and definitions of impact scores, see Impact score.
