Well, I imported the Hibernate2 sourcetree last night. Its in
its own module which means that for the next couple of months
we need to be *very* careful about handling patches. Bugfixes
and minor improvements must be applied against *both* trees.
(New features need only go into the Hibernate2 module.) As
promised, the following changes were made:
* packages are now net.sf.hibernate.*
* project structure is changed; all java is now in src dir
* code and tests relating to toplevel collections and  subcollections 
was removed

I have created a new hibernate-mapping-2.0.dtd, since we no
longer need the <collection>, <subcollection>, <generated-key>
elements and since collections may no longer appear beneath
the root element.
In the new DTD, I have also renamed the 'readonly' attribute to 
'inverse', since its name was causing all kinds of confusion for new 
(and not-so-new) users.

Please vote on the following proposals:

* Rename the 'role' attribute to 'name' in all collection
 elements in the new DTD, for consistency with <many-to-one>,  <id> 
and <property> elements. The role attribute no longer
 has any extra semantics beyond being a simple property
 name.

I am +1

+1

* Change the default for unsaved-value to "null" in the new  DTD. The 
current default is surprising to new users.

I am +1

+1

* Change the default for default-cascade to "save-update"
 in the new DTD.
I am undecided ... interested to hear the views of others.

+0

* Remove the exception that occurs if you save an object
 that is already associated with the session. This
 makes save() consistent with saveOrUpdate().
I am probably a +1 on this

+1

* Remove the exception that occurs if you delete an object
 that is already deleted in that session.
I am undecided. The current behaviour forces people to
think about who "owns" an object, who is responsible for
deleting it. However, it *can* be a pain in the ass.
In particular it means that:
session.delete("from o in class java.lang.Object");
