I just rolled the release for View 2 alpha 4. One important thing is that this should help people get back in sync with CCK; yched had been staying on the very bleeding edge of the handlers I'd created, and as a result people with the newest CCK but still using Views 2 alpha3 had problems. Sorry about that, folks.

The big new feature in this release is relationships. Here is the easiest way to understand relationships:

Go create a node type. Call it 'track'.
Create two more node types. Call them 'album' and 'artist'.

Create a node reference on 'track' that points to 'album'. Create a node reference on 'album' that points to 'artist. (You need CCK for this).

Now create some tracks, artists and albums.

Create a view. Change the style to table. Go to relationships. Add both the nodereferences you just created. Then go to fields. Add Node: Title and Node: Body three times. On the second Node: Title and body, set the relationship to 'album'. And on the third, set it to 'Artist'.

Preview.

Here's the release, and all its notes: http://drupal.org/node/239997
