0.66.0 - March 2026

This release introduced a major change related to WAREHOUSE parameters generation and resource_constraint.

Changes

• It is no longer possible to use parameter resource_constraint to specify warehouse generation using values STANDARD_GEN_1 and STANDARD_GEN_2. Parameter generation should be used instead.

Reason

This change is requires in order to support the upcoming change in bundle 2026_02: https://docs.snowflake.com/en/release-notes/bcr-bundles/2026_02/bcr-2225

How to adapt config?

Edit warehouses.yaml config file.

1. Find and replace values resource_constraint: STANDARD_GEN_1 with generation: 1.

2. Find and replace values resource_constraint: STANDARD_GEN_2 with generation: 2.

SnowDDL default warehouse generation is still 1. Warehouses without explicitly set generation remain on "generation 1" and are not affected by this change.
