Somehow BetaNews found a copy of FeedDemon 1.6 Beta 2 on my site and linked to it.
Unfortunately, this wasn’t the final beta 2 build – it was just a private build I made for a few testers. As such, it’s definitely not stable, so if you’ve installed it, I strongly recommend that you revert to beta 1. The real beta 2 will be out early next week.
