Currently our plan is to move to 1.5x around the time the DigiX ships - 1.5x was designed for alternative boards like the DIgispark and will allow it to work with alot less hacks. We feel it is better to focus our efforts on that then keeping up with 1.0x versions that rarely have any significant changes.
Is there anything is 1.05 (over 1.04) that you find is needed? If so, let me know and we'll consider a 1.05 version in between.
