Re: [hibernate-dev] SchemaManagementTool changes for 5.1 (was Re: 5.1 tentative release date)

When you say dropping, what would be the alternative for CLI users? It seems like a strong change to do in a minor revision. What are the required changes you need to do here? My hope would have been that the API of these tools would not have to change. 2016-02-02 22:10 GMT+01:00 Steve Ebersole <steve(a)hibernate.org&gt;: > Part of the work here is going to require significant changes to > org.hibernate.tool.hbm2ddl.SchemaExport, > org.hibernate.tool.hbm2ddl.SchemaUpdate and > org.hibernate.tool.hbm2ddl.SchemaValidator.
