 #### *(behavior change)* Validation to column type added
 While solving issue [#2733](https://github.com/Snowflake-Labs/terraform-provider-snowflake/issues/2733) we have introduced diff suppression for `column.type`. To make it work correctly we have also added a validation to it. It should not cause any problems, but it's worth noting in case of any data types used that the provider is not aware of.
 
+### snowflake_procedure resource changes
+#### *(behavior change)* Validation to arguments type added
+Diff suppression for `arguments.type` is needed for the same reason as above for `snowflake_table` resource.

 ## v0.88.0 ➞ v0.89.0
 #### *(behavior change)* ForceNew removed
 The `ForceNew` field was removed in favor of in-place Update for `name` parameter in:
