The Five team is happy to announce the release of two Five bugfix
releases, 1.2.5 and 1.3.6, a Five 1.4 final release and another Five
1.5c beta release today.
What is Five
Five is a Zope 2 product that allows you to integrate Zope 3
technologies into Zope 2, today. Among others, it allows you to use
Zope 3 interfaces, ZCML-based configuration, adapters, browser pages
(including skins, layers, and resources), automated add and edit forms
based on schemas, object events, as well as Zope 3-style i18n message
We've tried to keep the Five experience as close to Zope 3 as
possible, so this means that what you learn while using Five should
also be applicable to Zope 3, and viceversa.

About Five 1.4 and 1.5
Five 1.4 and 1.5 are feature releases. They are basically equivalent
except that Five 1.4 works with Zope 2.9/3.2 (only) and 1.5 works with
Zope 2.10/3.3 (only). Five 1.5 will be included in Zope 2.10.
Most important features are:
* Added viewlet and content provider support. A big thanks to Alec
Mitchell and his helpers at the Archipelago sprint for making this
* Add zope.formlib support. Please see ``doc/formlib.txt`` for more
information. A big thanks to Jan-Wijbrand Kolman for this.
* Port zope.testbrowser to Zope 2. You can now use
Products.Five.testbrowser.Browser in functional tests. Much thanks
to Brian Sutherland.
* Add python-packages-as-zope-products support which basically allows
for using any python package as a zope product without it having to
live in Products/. Much thanks to Rocky Burt for this.
Zope 2.10 and Five 1.5 are also a big milestone in the convergence of
Zope 2 and Zope 3, for it is no longer necessary to mark classes with
five:traversable and five:defaultViewable to enable Zope 3 view lookup
functionality. A big thanks goes to Lennart Regebro and Michael
Kerrin for making this possible!
Changes in Five 1.2.5, 1.3.6, 1.4 (vs. 1.4c), 1.5c (vs. 1.5b)
* Fixed an issue where <browser:page> based views that didn't have
template or attribute defined weren't getting BrowserView mixed in.
* Fixed an issue where new-style classes could not be used for
view components with <browser:page>.
* Five.testbrowser does not swallow cookies anymore, based on patch by
* Five.testbrowser capitalizes headers in the same way as the Zope2
HTTPResponse. i.e. content-length -> Content-Length.
