OS versions are usually identified by a major and minor number, two digits each (including leading zero for values below 10). The OS shows its version in the form MM.mm.cccc, where MM is the major, mm the minor, and cccc a four digits value that varies with the calculator model and thus is not suitable for identifying the OS version (the same build, when run on two different calculators, can give different values for cccc).
Casio appears to respect the meaning of "major" and "minor": between 01.xx releases, the features introduced were not all that important, and while OS 02.00 did not introduce any radical changes, it added some easily visible and important features.
Each OS build includes a timestamp, presumably of the build time, that is independent from the OS release date, but usually close to it. The timestamps are in the form YYYY.MMDD.HHmm, timezone unknown.
