Behavior Change Log¶

To help you manage your operations and minimize disruption to your Snowflake service, we document behavior changes that may impact your usage, including:

Upcoming pending changes that can be enabled (for testing), unless otherwise noted.
Recently implemented changes that were previously pending/disabled.

For behavior changes that are not associated with a specific behavior change bundle, see Unbundled Behavior Changes.

If you have questions about any of these behavior changes, please feel free to contact Snowflake Support.

Upcoming Pending Changes¶

The following table lists behavior changes that are pending. If the change is in a monthly behavior change bundle, the bundle is currently disabled, but can be enabled (for testing purposes).

To enable a bundle that is currently disabled by default, use the SYSTEM$ENABLE_BEHAVIOR_CHANGE_BUNDLE system function. This is typically done in your non-production accounts (for development and testing purposes).

Important

All information in this table, including planned versions and dates, is subject to change; the information is provided only as a guideline for any updates you need to make to accommodate the changes.

If a link is not provided to the individual pending behavior changes, the release in which the bundle was introduced has not started or is is still in progress.
