* The code for finding Open Access versions of otherwise paywalled scientific articles has been further improved
* You will now find a familiar tabbed interface, ensuring quick and easy access to all features
* Settings, which previously were only available through the settings app or as part of the on-boarding tutorial, have now been added into the main interface
* You will now get some subtle feedback via haptic feedback, if supported by your device
