5.9 Operating system to 5.1... hmmmmmmm

I’m assuming that the operating system is current at 5.10 and the reading of 5.9 should probably have been 5.09? I don’t want to go backwards. Are we counting like…

5.9 = 5.09
5.10
5.11
5.12

The dot isn’t a decimal point, it’s a divider between the major version number and the minor version number.

The minor number was 9 (nine), so the next one is 10 (ten).

It’s basic software versioning.
