We should also be updating the build number of the zip file each time we make a change otherwise its difficult to know if you have the latest code base or not. This is the point of the build number part, the version does not change but the build does just like any VMware product

@GaryJBlake moving forward, will update the build numbers as changes are done, along with change log in the description.
