15+
1.0.1 14-1-2016 sample0_us
16+
1.0.2 10-2-2017 1, 2, 3, 4 channels
17+
1.0.3 10-2-2017 probeA sampleB probeABC probeABCD to avoid mistakes, all unsigned int -> int, added stop(), sizeof(int)
18+
SerialUSB -> Serial (incl. <Albert.h>), short
19+
1.0.4 10-3-2017 for ISR measurements do show() in loop()
20+
1.0.5 28-1-2018 renamed sample to probe, Scope to SWscope
