Changes in 1.0.0-beta

It's time to move to 1.0.0! We were running out of numbers, so it was about time to move on and start with the magic number 1.0.0 (ok, still beta).

To celebrate, we have added more settings that can be set/overrulled for individual devices. decimals, use_median and restore_state can now be set at device level. We have removed the rounding option, as it wasn't adding much. The same can be achieved by using a large number of decimals.
