To be clear, I don't create new images every time I make additions and bug fixes so I recommend to use the update functionality from the web interface on regular intervals. There is also an update.sh script if you log on by SSH but that is not the recommended way to update. It is not allways updated and you may run into file permission problems.
This year I hope to bring in some new functionality:
User friendly support for CEC commands
More data upload/download functionality
... (what do you wish for?)
Happy new year!
