title: LiquiBase -- Any way to output change log sql to a file in 2.0.5?
body: <p>Currently I am integrating Liquibase with my spring application using <code>liquibase.integration.spring.SpringLiquibase</code> bean</p>
  
  <p>From java doc, tt is plausible to know there is an property <code>sqlOutputDir</code> to that bean class so that the sql can output to external file.</p>
  
  <p>However, the feature seems not exist in latest 2.0.5.</p>
  
  <p>So, the question is, what is the current <code>equivalent method or function</code> to output changeLog sql to external file, or the feature just have been totally removed forever?</p>
  
  <p>Please give a hint, thanks a lot.</p>
