Firmware 0.70 is now out and wikipage has been updated accordingly.
There are a couple important things to note after the upgrade:
* Some remote control keys have been reassigned, so e.g. input selection is handled differently than in previous firmwares. Remote control picture on the wikipage shows new functionality. Also, modified keymaps need to be reprogrammed after the update since several new keys are added.
* Saved settings from previous firmwares are no more valid so they must be created from scratch
