+* `sea_orm::ColumnType` was replaced by `sea_query::ColumnType` https://github.com/SeaQL/sea-orm/pull/1395
+    * Method `ColumnType::def` was moved to `ColumnTypeTrait`
+    * `ColumnType::Binary` becomes a tuple variant which takes in additional option `sea_query::BlobSize`
+    * `ColumnType::Custom` takes a `sea_query::DynIden` instead of `String` and thus a new method `custom` is added (note the lowercase)
