title: What version numbering scheme do you recommend?
body: <p>My question is, which version-naming scheme should be used for what type of project.</p>
  
  <p>Very common is major.minor.fix, but even this can lead to 4 number (i.e. Firefox 2.0.0.16). Some have a model that odd numbers indicate developer-versions and even numbers stable releases. And all sorts of additions can enter the mix, like -dev3, -rc1, SP2 etc.</p>
  
  <p>Exists reasons to prefer one scheme over another and should different type of projects (i.e. Open Source vs. Closed Source) have different version naming schemes?</p>
