Omz:software has released a major update to its popular NewsRack RSS reader for the iPhone and iPad adding iOS 4 support and several additional features and improvements. NewsRack 2.5 now supports background task completion and fast app switching on multitasking-capable iOS 4 devices and provides high-resolution graphics for the iPhone 4 Retina Display. A new slideshow mode is also now available for iPad users. Additional improvements include much faster synchronization with Google Reader, the ability to mark articles as unread, synchronization of Google Reader shared items, Instapaper Mobilizer support and the ability to download older news items from Google Reader. The update also provides a number of user interface improvements on both the iPhone and iPad platforms, although themes are no longer available for iPhone and iPod touch users. NewsRack 2.5 is currently not compatible with the iPhone 3G with iOS 4; the developer indicates an update for this will be “follow shortly.” The iPhone 3GS and iPhone 4 are fully supported, as are any devices running iOS 3.x. NewsRack is available from the App Store for $5 and is a free update for current users.
