Unread 2.4.2 is available in the App Store. This adds a compatibility fix for NewsBlur.
NewsBlur got a big infrastructure update last week, and NewsBlur is now more strict about the format of API requests. This triggered an incompatibility with Unread marking articles as read, unread, starred, and unstarred. I fixed that in the version 2.4.1 update. An additional compatibility issue that I had missed was that signing in to a NewsBlur account from Unread had stopped working. This update fixes that.
