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 catalogs.

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 possible.
• 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 1.2.4/1.3.5 and 1.4c (compared to 1.4b)

• Made sure that events are fired as expected in add and edit forms.
• Made sure LocalizerLanguages class normalized language codes to xx-yy, instead of xx_YY or xx-YY.
• Fixed a problem with the new traversal look-up order and the root object (OFS.Application.Application).
