I'd try to follow standards, this is supposed to be primarily understood by 
developers. semver is the most sensible thing I know of when it comes to 
versions. #11 is pretty sensible:
http://semver.org/#spec-item-11

I'll just copy their example and would like us to follow it:
Example: 1.0.0-alpha < 1.0.0-alpha.1 < 1.0.0-alpha.beta < 1.0.0-beta < 1.0.0-
beta.2 < 1.0.0-beta.11 < 1.0.0-rc.1 < 1.0.0.


I agree with Robin in that we should make it easier to test, so for me the 
priority would be to get nightly builds out there and make it easy to install 
them through the online installer. Currently there is no sensible way for the 
community to help out since all the code and procedures are internal. We're 
cleaning many things up (one problem that The Qt Company has is that we have 
not stream-lined releasing and packaging the different products enough, Qt for 
Application Development and Device Creation for example are not packaged 
completely the same way...).

Cheers,
Frederik
