If the change involves only _addition_ of new headers, there is no need 
for a version number change, technically speaking.

The only time the version number needs to change is if the change is not 
backwards compatible, and I'm hesitant to make small changes like that. 
It would be much better to bundle up changes and make a version number 
increase that incorporates all of them.

Additionally, we need to support the 'old' version for some period of 
time if possible, at least for one release cycle.
