Subject Re: Is PB stable in HEAD?
Date Wed, 23 Mar 2005 18:08:51 GMT
hi tom, andrew,

there are also some additional features in 1.1:

- non-pk relationships
- better support for expression in attributes
- discriminator-descriptor to replace ojbConcreteClass
- mixing of mappings 1-table/1-class and 1-table/many classes
