Actually, you can use Version REVISION to check your minor version as well.
Code:
0.4.Ram Disk:> version
Kickstart 40.68, Workbench 40.42
0.4.Ram Disk:> version revision 68
Kickstart 40.68, Workbench 40.42
5.4.Ram Disk:> version version 40 revision 68
Kickstart 40.68, Workbench 40.42
5.4.Ram Disk:> version version 40 revision 42
Kickstart 40.68, Workbench 40.42
0.4.Ram Disk:>
As you see, Version by default checks your Workbench revision.
