[Modeling-users] Release: 0.8 - under the GNU GPL

[Sebastien B. <sbi...@us...>]

        Hi,

  The Modeling Framework, v0.8, and the Notification framework, v0.4, were
released today. Both are now under the GNU General Public License.

  Most important changes in these releases:

  - Modeling package: 

    EditingContext's new feature: it can now examine updated and inserted
    objects to detect the newly created objects in relation, so that they are
    in turn inserted into the EditingContext. CustomObject (resp.)
    ClassDescription has a new method to support this feature:
    propagateInsertionWithEditingContext (resp. propagateInsertionForObject)

    EC.insertObject() was consequently changed to issue a warning instead of
    raising ValueError when it is called with an already registered object AND
    EditingContext.propagatesInsertionForRelatedObjects() is true

    This feature is related to the natural way the ZODB behaves, where the
    statement 'obj.foobar=obj2' makes obj2 persistent within the zodb when obj
    is already persistent.


  - ZModelizationTool: 

      - Feature added: it is now possible to create a relationship (and its
        inverse) in one single step --includes: automatic generation of the
        foreign key, if requested

      - Database schema generation: Added a button to show (as opposed to:
        execute) the SQL statements that would be executed by the other button
        'Do it!'

  All other changes are bug-fixes --see files CHANGES in their respective
  package.

  An other release in planned within a month ; it will mainly address
  RFE#617997 (https://sourceforge.net/tracker/?group_id=58935&atid=489338).
  It will make it possible to make changes in a subset of a set of objects and
  then commit all changes, or discard them, as a whole. In other words, it
  will be possible to think ``transactional'' at the OO-level.
  ETA: ~Feb.15,2003.
