title: Maven artifact version for patches
body: <p>I'm currently working on <a href="http://blog.pdark.de/2011/03/18/project-dash-m4e-tools-create-maven-artifacts-from-eclipse-plug-ins/" rel="noreferrer">Maven tools for Project Dash</a>. One of the open issues is how to handle mistakes.</p>
  
  <p>Maven central says: Nothing published ever changes. This is because Maven never tries to figure out whether a release has changed (unlike for SNAPSHOTs).</p>
  
  <p>But I might have to create a new "release" of, say, part of Eclipse 3.6.2. Which version number should I use? <code>3.6.2.1</code>, <code>3.6.2-1</code>, <code>3.6.2_1</code>, <code>3.6.2pl1</code>? Why?</p>
