New firmware BETA41 now available!
Please read the changlog ( http://spectran-developer.net/typo3/index.php?id=12&L=1 ) first before you update to this new version since it can change the calibration of your unit so you might need a recalibration at the Aaronia lab!
So, as far as I understand the changelog I can not say if the update will change my calibration or not?
So it is little bit like russian roulette? If I have luck I can use the device furthermore, otherwise I need to send it to Aaronia for calibration with costs?

Exactly. This is a "hard" update at your own risk thats why you get multiple warnings (also in the firmware updater software).
But there is no need to do it.
