When building a new version of a Device Driver you will want to adjust the Version to indicate this is a new driver (1.0.0) or an edit to an existing Driver (1.0.2).
Edits to an existing driver will change the last character in the Version number. 1.0.1
If minor changes are made, including multiple added commands or adding supported models change the middle number. 1.1.0
If major changes are made, including a complete change in protocol upon firmware updates change the first number. 2.0.0
