The 0.2 implies two "point releases". Traditionally these increment the value after the decimal point in a version number.

so:

8 + 2 = 10, therefore 1.10.

It's best to view the version number as a string rather than a decimal number.

This is a somewhat old-school way of versioning and common in open source software. Personally, I prefer something more intuitive and don't see anything wrong with MongoDB being at version 2.0!

The point of a major bump is to say to the ops team/sysadmin "HEY! We actually changed some stuff. You probably want to check with your programmers to see if any of these changes will effect our client code".

I think if they want to keep it purely arithmetic they should drop the period and just use integers.
