Only add/remove field is supported. Field rename and field attributes change are not supported.

There is no plan to support.

BTW, this following command cannot create modified column either: ./mvnw compile liquibase:diff

I consider if this feature should also be a basic feature for maintaining database. Field rename and field attributes change might be a high frequent behavior at development stage. I am not sure, but thanks so much.
