[Modeling-users] Release: 0.7a5

[Sebastien B. <Seb...@in...>]

        Hi,

  A new release is available at http://modeling.sf.net.

The major enhancements and changes are:

  - Added the ability to check the model against the most common errors made
    when designing a model. This feature is available through the
    ZModelizationTool.

  - Added support for MySQL, and the PostgreSQL db-adaptor can now use another
    python DB-API2.0-compliant module: psycopg --this one is now preferred to
    the module 'pgdb', when both are available (I noticed that I got better
    performance with the former than with the latter).

    An AbstractDBAPI2AdaptorLayer is also distributed to make it easier to
    write new adaptors for databases for which a python DB-API2.0-compliant
    module is available.

  - The DatabaseAdaptors, previously distributed separately, are now shipped
    with the core package. Its location changed as well: they are now
    available under the package 'Modeling.DatabaseAdaptors' (was: package
    'DatabaseAdaptors') --see also: specific instructions for upgrading,
    below.

  - Added support for Date objects

  - Added full support for python2.2

  - lots of bug fixes! --> See the packages' files 'CHANGES' for more details

Instructions: Upgrading from 0.7a3 to 0.7a5
------------

  * Delete $prefix/lib/python2.1/site-packages/DatabaseAdaptors

  * If you are using the ZModelizationTool to design your models:

    - save your models

    - delete and recreate your instance of the ZModelizationTool

    - reload your models from the previously saved xml files.

  * Install as usual: the core (0.7a5) and the NotificationFramework (0.3) are
    installed via the python-distutils, while the ZModelizationTool, available
    in the ZModeling package, is installed in the Zope/Products directory.
