Greg Knaddison (greggles) over at masteringdrupal.com did a screencast talking about some of the big changes in Views 2. If you haven't looked at Views 2 yet, it's worth a look to see what's changed.

I don't have a lot of time for Views 1 right now, but there are a couple of bugs in Views 1.6 that really need to be fixed. I've been hoping for a year now that someone would volunteer to write these patches, but no one has.

Ironically, both of the patches I need relate to taxonomy, and both of these problems exist because Views is trying to use Drupal's API but the API is simply not adequate to Views' needs.
