I've released a preliminary version of the new phpNode, it uses a completely different format from the old one. Currently many of the features are present, but they will be added as soon as we have time. Expect 1.0 alpha in a couple weeks.
We have decided that the current version of phpNode is not what we would like in the application, and so we will be starting over with the project. We will add many of the things we want in it, and change many things about it. The old versions will still be available to download, as they work [somewhat].
The new version adds many admin features (editing of users/groups), and fixes many bugs.
The phpNode 0.0.4 release is now available. This release fixes many bugs, and adds the register user functionality. Still to come are administration features and a better install script.
The first publicly available version of phpNode, codenamed Archer, has been released. This version is partially functional, with create node and edit node functionality present.
