Unbundled behavior changes¶

Unbundled behavior changes are not associated or released with a behavior change bundle.

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

Recently implemented changes that were previously pending/disabled, were not part of a behavior change bundle, and cannot be disabled.
Upcoming pending changes that will not be part of a behavior change bundle and cannot be enabled in advance.
Canceled behavior changes that have been removed from BCR bundles and will not be implemented.

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

Recently implemented changes¶

This table lists behavior changes that were implemented independently of a behavior change bundle. These changes include certain types of changes to Snowflake clients (connectors, drivers, etc.), platforms, and libraries. Such changes cannot be disabled.
