On behalf of the Zope 3 development team I'm proud to announce the final
Zope 3.3.0 release. There were no changes since the 3.3.0 release candidate.

Zope 3 is the next major Zope release and has been written from scratch
based on the latest software design patterns and the experiences of Zope 2.

Cleanup of the Zope 3 packages has continued to ensure a flexible and
scalable platform. We continued the work on making the transition from
Zope 2 to Zope 3 by making Zope 2.10 use even more of the Zope 3
packages. But the transition is far from complete yet. **You can't run
Zope 2 applications in Zope 3.**



Installation instructions for both Windows and Un*x/Linux are now
available in the top level README.txt file of the distribution. The
binary installer is recommended for Windows.

Zope 3.3 requires Python 2.4.1 to run, Python 2.4.3 is recommended. It
does **NOT** work with Python 2.5 yet. You must also have zlib installed
on your system.

Most Important Changes Since Zope 3.2

   - Provided a new component registry API that allows multiple
     component registries to be combined more flexibly than before.
     See 'zope.component.interfaces.IComponentRegistry' for more

   - Greatly simplified local-component registration.
     See 'zope.component.interfaces.IComponentRegistry' for more

   - Moved many packages out of zope.app to make them easier to use
     outside of Zope.

   - Change the session credentials plugin to make it configurable
     in which fields it looks for the credentials.

   - Added a new API for collating text.  You can now adapt
     a locale to 'zope.i18n.interfaces.ILocales.ICollator'.  You can
     then use that to sort strings, such as menu entries, in a
     locale-specific fashion.

   - A new 'zope.annotation.factory' helper function that makes
     it easier to create annotations. Also added a README in
     'zope.annotation' which explains how to use it.

   - Added a more complete set of widgets for fields that use
     iterable sources.  These widgets now mirror the set provided
     by vocabulary-based fields.

   - Added a cleaner and more robust API to testbrowser for setting
     file-upload data.

   - Deprecated several ZCML directives:

     * factory

     * vocabulary

     * content (as an alias to the class directive)

     * modulealias

     * renderer:renderer

   - The 'browser:layer' directive and the 'ILayer' interface
     has been deprecated.  Registering layers has become obsolete,
     layers should be created as interfaces extending

   - The 'browser:skin' directive has been deprecated.  Skins
     should be created as interfaces extending 'IBrowserRequest'
     and can be registered using a simple 'utility' directive.

   - The 'ISkin' interface has been renamed to 'IBrowserSkinType'.

For a complete list of changes see the 'CHANGES.txt' file.
