Help Test Plone 3.3

Plone 3.3 is coming. Please help make it perfect!

Plone 3 release manager Wichert Akkerman has tagged the first beta release of Plone 3.3. It's time to test! Wichert's anticipating a short beta cycle, so don't wait.

If you've already got a Plone 3.2 installation, you may test 3.3b1 by just changing your buildout configuration's version extend specification from:

extends =


extends =

and running buildout. This is a beta, so make sure this is a test instance.

Unified and OS X installers are also available at on the 3.3 release page.

As with previous Plone 3+ releases, this release is expected to have a high degree of compatibility with other 3.x releases. No add-ons should break.

Improvements in Plone 3.3 include:

Link type should automatically redirect when accessed directly
Links should be capable of doing automatic redirection.
Resource Registries Improvements
Allow Resource Registries to use conditional comments for CSS to bring the IEFixes.css into the registry and allow external references to resources for all registries.
Standardizing our use of INavigationRoot
Plone has the INavigationRoot marker interface which supports rooting your tabs, navigation, breadcrumbs, sitemaps and searches to a specific container inside of a portal which itself is a INavigationRoot. Some areas of this need to be cleaned up and standardized to follow a consistent convention.
Minor i18n upgrades
Include PloneLanguageTool 3.0 and PTS 1.5.
Disable inline editing by default
The current inline editing behaviour as introduced in Plone 3 was a mistake: it is a cool technology to show off, but in practice accidental clicks very frequently lead to unwanted edit-screens.
Adapterise the Extensible Indexable Object Wrapper
Make it easier to register ExtensibleIndexableObjectWrapper attributes with adapters
Improve locking configurability
This PLIP proposes to a) make it harder to accidentally leave content items in a locked state, and b) make it easier to adjust the lock timeout or disable locking entirely.
Clean up auto-sort, auto-order code
Clean up, i.e. remove all code related to auto-sorting / auto-ordering folder contents as this feature was implemented for Plone 2.1, but never got enabled. Basically this proposes to revert
Replace workflow history viewlet with content history viewlet
Plone stores both workflow history and versioning history for objects. Only workflow history is shown in a viewlet in current Plone versions. I propose to show all history data.
View for rendering events as an iCalendar file
Make it possible to subscribe to Plone events in the standard iCalendar format.
Automate ZCML Loading for Plone Plug-ins
Enable automatic plugins for Plone with z3c.autoinclude
