What do the version names mean?
ProCall DataCenter is released in a rolling-release manner. This means there are no major releases but smaller incremental features releases (approx. 3 feature releases) every year and additionally one maintenance release each month.
Version numbering results as follows: Year and month of the feature release and increment of the maintenance release. Example: 2206.0 → Feature release published in June 2022. A maintenance release based on this in July is then published as 2206.1.
