Garden Linux is versioned by the day of the created binary release (image):
The Release 1 would have been when the project was created on March 31st 2020. Since there was much more coding to be done the first stable release was 27 -> created on April 27th 2020.
Release day (as in Date) - April 1st 2020 (+1) = version number
27.04.2020 - 01.04.2020 + 1 = 27
01.06.2020 - 01.04.2020 + 1 = 62
All this calculation is done in bin/garden-version.
