    If we add new type to version 1.7, it can't work with  version 1.6 where this type is
absent, that's why I am adding support only for +1 version. At this point in my implementation,
1.6 can work with 1.6 and 1.7. 1.7 can work with 1.7 and 1.8.

all the running drillbits are in the same version.
> Using drillbits of different version can lead to unexpected results.
