I had been doing work on the Silt server recently, and I just got back to some of my roadmap issues for the 4.0 release. This morning I polished off the handling for proxy redirects. That's a situation you get when you stay at a hotel, and buy 24 hours of service. When that expires, all http requests get redirected (permanently) to the "please buy it agan" page. Very nasty, especially when every feed you have gets redirected :/
So, I now take note of redirects, and if there are too many to the same url, the feeds get restored, Bf is taken offline, and the user is warned. Much nicer than hoping you have a backup handy. I also enhanced the Enclosure handling support - each feed now has a "should download enclosures" property. By default, it's set to true, but you can override that. So if you grab the latest Bf update and the latest EnclosureHandler plugin, you can set feeds to be ignored in the nightly download cycle.
So I'm down to two items in my roadmap - tabs in the html display, and a "define your own feed wizard" option. I think I'll tackle that one next.
