I updated the 2.8 parcels on the site - if you are running 2.8, it should detect the new parcels as being available and allow you to download them. You'll have to restart BottomFeeder - that's the way the update is implemented in 2.8. That could change in the next release, but I'm not quite sure yet. So what's new?
The Feedster and Google searches were having problems on error conditions due to a namespace lookup problem. That's addressed, and one other tweak as well - if you search from the item pane, the search uses the title of the item. Searches from the HTML pane will use the selected text in the item pane.
