[Zope-dev] Heads-up: Zope 2.8, Zope 3 and Five

[Brian Lloyd]

Hi all -

At the Paris sprint, a plan was hatched to integrate Five into 
Zope 2.8, which Jim, Andreas and others responsible for release 
management have endorsed.

This will hopefully actually help spur 2.8 to the finish line as 
well as begin to provide an upgrade path into the future for Zope 2 
developers.

What this will essentially mean for is that:

  - Five will ship in the core distribution with Zope 2.8

  - A subset of the Zope X3.0 packages will ship in the
    core distribution

...so it will be possible to use a number of Zope 3 technologies and 
patterns in existing Zope 2 applications.

The Five integration layer provides support for Zope 3 interfaces, 
Zope Configuration Markup Language (ZCML), adapters, views, 
utilities, schema-driven content, and Zope 3 add and edit forms.

Note that the Five layer does *not* attempt provide a ZMI user 
interface for Zope 3 components.

Zope 2.8+ will include the essential Zope 3 packages, so it will 
not be necessary to install Zope 3 separately.

If you are interested, there is now a 'five-integration' branch 
in Z2 SVN where this work is going on.
