Marco Arment has released an update to Instapaper, his popular offline reading app for iOS. Instapaper 4.2 adds several new user interface improvements including a new redesigned Fast Pagination mode that improves accuracy and performance when turning pages and adds new page turning animations and gestures similar to iBooks.
A new draggable dot bar can also now be used in place of the scroll bar in pagination mode. A new two-finger swipe gesture has been added for closing an article view, an option is also now available to automatically switch to full screen reading view after a few seconds.
The new version also allows users to manually select the Twilight Sepia colour theme; previously it only appeared during twilight hours when automatic day/night mode was enabled. Instapaper 4.2 now requires iOS 5.0 or later and is available from the App Store for $5.
