GitFlow: optional major.minor.patch release formats

GitFlow currently can't be set to default to major.minor.patch release formats.

Every time I start a new release it auto-bumps minor despite the most
recent release branch being in major.minor.patch format (i.e. 4.7.11 ,
start release creates 4.8 not 4.7.12).

My understanding is that some other GitFlow products support the 3-level release format and fall back to major.minor.

Does anyone know if the system level gitflow for MacOS supports the 3-level release format?
