Checkmk versions & editions

1.6.0b1	Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk MSP (CME)
1.5.0b6	Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk MSP (CME)

When using pretty outdated "Do hardware/software Inventory" rules which have been saved before 1.4, this could lead to crashing Check_MK and Check_MK HW/SW inventory services with errors like this:

'NoneType' object has no attribute 'get'

Workaround: Open this ruleset and save the rules in the relevant folders. The configs will then be transformed and rewritten in the current format which prevents this crash.
