title: Which version of scala should I release my library to?
body: <p>When I was releasing for scala <code>2.9.x</code>, I simply had this line in my build.sbt:</p>
  
  <pre><code>crossScalaVersions := Seq("2.9.0", "2.9.0-1", "2.9.1", "2.9.1-1", "2.9.2")
  </code></pre>
  
  <p>But now, scala <code>2.10</code> is out, and I'm confused. My intuition was that I should have something like this:</p>
  
  <pre><code>crossScalaVersions := Seq("2.10.0")
  </code></pre>
  
  <p>But I noticed, that when I have scala version set to <code>2.10.0</code>, sbt searches for artifacts ending with <code>2.10</code>, not <code>2.10.0</code>. What's going on here? What version should I use?</p>
  
  <p><strong>EDIT:</strong> Also, if I do <code>publish-local</code>, the artifact also ends up being suffixed by "_2.10", instead of "_2.10.0".</p>
