title: Query all issues with a fixVersion = next non-released version in Jira
body: <p>I would like to create a query that returns issues based on a version type field that is equivalent to the next unreleased version on a particular number branch sequence.</p>
  
  <p>For example:</p>
  
  <pre><code>fixVersion IN ('1.7.1') 
  </code></pre>
  
  <p>would give me all of the issues where the fixVersion is set as 1.7.1</p>
  
  <p>What I would like to do is be able to create a query that selects the next unreleased version in the 1.7 branch</p>
  
  <p>For example:</p>
  
  <pre><code>fixVersion IN (NextUnreleasedVersion)
  </code></pre>
  
  <p>In addition I would like to get a version that is the last released version in a similar manner.</p>
  
  <p>Is it possible to do this with the standard Jira query mechanism.</p>
