2.0 should have a much better algorithm for calculating K yes, this is completely cosmetic though it makes no difference to the images (see below). > I'm wondering what happens to photos developed with the current version. > Many times i make little adjustments to the color temperature and don't use > a preset.

Temperature values are just a helper, they're not used directly. Whatever red/green/blue multipliers have been set for the image will still be used and the temperate value is calculated from these on display. Having a temperature slider is just a convenient way to label the slider in a way that's reasonably consistent between cameras. In this case the consistency was not there but the slider worked just as well and the WB that it set is perfectly valid and will be used going forward. To further reinforce the point we don't break history stacks, so if for some unavoidable reason we had to introduce some kind of change we'd have told everyone about it.
