NB:

version updates at the 0.x level usually require a state reset because they change/add/remove state variables, i.e. should never be done in the middle of an experiment.
version changes at the 0.0.x level can be flashed at any time. They do make state changes and thus will resume their current state correctly after flash+restart.

version 1.5.0

rename publishing.publish to publishing.record to clarify how it relates to GUI recording on/off
hardware signal.calculation added with two possible values: mean (default, average signal values) or mode (determine peak of the signal values)
optical density reading.stopLights added for users to decide whether lights turn off or stay on during OD reads (default is stopLights = yes)
system state.autoSendOnStartup added for users to decide whether to send the state snapshot whenenver a device that's recording starts up (e.g. after power cycling), default is ON
introduce particle variable getSddsSystem as convenience access piont that returns the system variable tree only (~800 bytes in size) except for the variable publish intervals (which can be any size)
change default read interavl to 2 min and default publish interval to 20 min

version 1.4.0

cooldown (wait time until dark measurement after LED beam turned off, default: 500 ms) added - this value is saved in the micrologger state
zeroPause (wait time until zeroing when automatic gain adjustment happens during zeroing, default: 60s) introduced - this value is saved in the micrologger state
default values for warmup (default: 3s) and wait (default: 0s) adjusted since the longer warmup leads to a more stable signal but usually does not require additional wait time anymore for the culture to settle
