Zope 3.1.0 candidate 1 released!
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.
It is in our opinion that Zope 3.1 is more than ready for production use,
which is why we decided to drop the X for experimental from the name. We
will also continue to work on making the transition between Zope 2 and Zope 3
as smooth as possible. As a first step, Zope 2.8 includes Zope 3 features in
the form of Five.
Please test this release carefully and send us any feedback! In particular, we have tried very hard to keep backward-compatibility with the previous X3 3.0 release, so please let us know if the new release breaks your code.

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 3.1 requires Python 2.3.5 or 2.4.1 to run. You must also have zlib installed on your system.
Important Changes Since 3.1.0b1
All of the outstanding issues in the to-do list were completed, which included many bugfixes and the removal of all outstanding XXX comments. There was also a lot of work done in fixing many places that were not translatable.
Most Important Changes Since 3.0
- New Pluggable Authentication Utility (PAU), which is similar in
philosophy to the Zope 2 PAS. The following features are available in
the in the basic PAU facility:
+ Credentials Plugins: Basic HTTP Auth, Session
+ Authenticator Plugins: Principal Folder, Group Folder
For a detailed description of the pluggable authentication utility, see
zope/app/authentication/README.txt. - Major simplifications to the component architecture:
+ Removal of the concept of a service. All outstanding services were converted to utilities: Error Reporting, FSSync, Authentication.
+ Site Managers are global and local now; adapters and utilties are directly registered with the site manager. Now global and local component registration and lookup behaves very similar.
+ Local registrations can now only have two states: active and inactive. This simplified the code so much, that
zope.app.utility,zope.app.registrationandzope.app.sitewere all merged intozope.app.component.+ Implemented menus as utilities. The API also supports sub-menus now.
+ Implemented views as adapters. Skins and layers are now simply interfaces that the request provides.
- Added an integer-id facility for assigning integer identifiers to objects.
- Added basic catalog and index frameworks.
- Added "sources", which are like vocabularies except that they support very large collections of values that must be searched, rather than browsed.
- Created a new granting UI that allows advanced searching of principal sources.
- Implemented a generic user preferences systsem that was designed to be
easily used in TALES expressions and via Python code. Preferences can be
edited via
http://localhost:8080/++preferences++/. A demo of the preferences can be found at:http://svn.zope.org/Zope3/trunk/src/zope/app/demo/skinpref/ - ZCML now supports conditional directives using the
zcml:conditionattribute. The condition is of the form "verb argument". Two verbs,have featureandinstalled moduleare currently implemented. Features can be declared via themeta:providesdirective. - Improved API doctool: Code Browser now shows interfaces, text files and ZCML files; the new Book Module compiles all available doctext files into an organized book; the new Type Module lets you browser all interface types and discover interfaces that provide types; views are shown in the interface details screen; views and adapters are categorized into specific, extended and generic; user preferences allow you to customize certain views; 3rd party modules can now be added to the Code Browser.
- Improved I18n-based number and datetime formatting by integrating
pytzfor timezone support, implementing all missing format characters, and reinterpreting the ICU documentation to correctly parse patterns. - Added
++debug++traversal adapter that allows you to turn on debugging flags inrequest.debug. Currently the following flags are defined: source, tal, errors. - Improved logout support.
- Added the HTTP request recorder, which lets you inspect raw HTTP requests and responses. It can be used to create functional doctests without requiring third-party tools such as TCPWatch.
- Developed a generic
browser:formdirective. It is pretty much the same as thebrowser:editformdirective, except that the data is not stored on some context or adapted context but sent as a dictionary to special method (by default).
