-Currently, only Sybase ASE, MSSQL with CS/BIN collation and Firebird without

-option are in case-sensitive mode.
+In this mode, CamelCase L</column_accessors> are normalized based on case

If you don't have any CamelCase table or column names, you can upgrade without

For example:

- has_many => { cascade_delete => 1 },
