A Second Beta for Plone 2.5

Another beta release of 2.5 is ready for testing

Many fixes and improvements have gone into Plone 2.5 since the last beta and it's time once again to get your development/testing instances ready and see if your products and sites upgrade properly, kick the tires and report any problems in the issue tracker!

Plone 2.5 is a release with a significant focus on improved infrastructure. This is the first release of Plone that utilizes Zope 3 technologies, and is an important step in transitioning Plone to use these components throughout the system.

Download Plone 2.5 beta here!(Windows and Mac OS X installers — including Universal or Intel binaries — should be ready sometime next week)

Notable features in this Plone 2.5 beta are:

New caching infrastructure
The CacheFu project now ships with Plone, and when installed can result in 10x to 40x faster page loads, depending on setup — while being entirely transparent to the end-user.
Pluggable Authentication Service
The new authentication structure in Plone 2.5 makes it very easy to integrate any kind of authentication with Plone. Plugins for LDAP and GMail (!) already exist, and more are easily added.
Support for XML exports of site configurations
It is now easy to replicate a particular site configuration across multiple instances, making it easy to create setup policies for sites.
Placeful Workflow
It is now possible to have workflow policies determined by location in the portal, not just by item type. This means that different parts of the portal can have different security settings, and entirely different workflow paths for the same types of objects.
Support for the latest technologies
Zope 2.9 and Python 2.4 are now supported by default.

Note: This release of Plone 2.5 requires Zope 2.9.3 and Python 2.4. When the next release of Zope 2.8.x is out, it will work with that too.

Upgrade Path

Is there a recommended sequence for upgrading a site to this? I'd be happy to test, but there's probably a "best path" to success for this. What I'm looking for is something like:

1. Backup your databases
2. Create new zope-instance, extract and copy new Products to products dir
3, Copy orig databases to var
4. start zope
5. Run portal_mirgration, update portal_catalog.

etc., etc.

I've tried the upgrade a bunch of times, but just get lots of errors...so perhaps I'm not proceding in the right sequence.

That is about right

You shouldn't need to update the catalog though. Please post the errors you get, with tracebacks in the issue tracker at https://dev.plone.org/plone (use your plone.org login).
