According to this new post from Derick Rethans, the eZ Components group has release the latest edition of their component set - version 2007.2.

Today we released the next version of eZ Components. In this release, there are two new components.

These two new components are:

• Tree - enables you to create, manipulate and query tree structures (with multiple compatible backends for gathering the data from)
• Webdav - allows for the quick and easy setup of a WebDAV-enabled server.

You can find out more about these components and many more included in the component library at the project's website (as well as this latest download).
