+### old grant resources removal
+Following the [announcement](https://github.com/Snowflake-Labs/terraform-provider-snowflake/discussions/2736) we have removed the old grant resources. The two resources [snowflake_role_ownership_grant](https://registry.terraform.io/providers/Snowflake-Labs/snowflake/latest/docs/resources/role_ownership_grant) and [snowflake_user_ownership_grant](https://registry.terraform.io/providers/Snowflake-Labs/snowflake/latest/docs/resources/user_ownership_grant) were not listed in the announcement, but they were also marked as deprecated ones. We are removing them too to conclude the grants redesign saga.
