Alexander Limi provides an update about development on Plone 3.0. (here’s a screenshot). My ebook site will be backed by plone 3.0. I’ll probably be jumping the gun a bit, deploying on a release candidate or beta 2 version. (Or maybe, I’ll just test all my 2.5 work against 3.0 and magically change over in May when everything is ready).
It’s always a debateable question about how closely you should match your deployment schedule with the latest release of a piece of software. If I were in the corporate world, I’d play it safer, but now that I’m on my own, I don’t mind the risks involved.
