Ebbinghaus 1.5 is now available. There are a lot of new features:

File Box Sharing
You are now able to share and publish your file boxes with just a few clicks.
With Ebbinghaus 1.5 you are able to activate and deactivate file cards.
You are also able to select multiple file cards and then click the study button. If doing so Ebbinghaus will only prompt the selected file cards (including the deactivated ones).
