title: Liquibase execution order of changes inside of changeSet
body: <p>We are using liquibase to split a column into two columns. This happens in three changes:</p>
  
  <ol>
  <li>Add the new columns via <strong>addColumn</strong></li>
  <li>Insert the data from the old column into the new ones via a <strong>customChange</strong></li>
  <li>Delete the old column via <strong>dropColumn</strong></li>
  </ol>
  
  <p>This works great, but I can not find any documentation on the order of execution of <strong>changes</strong>.
  I only found documentation on the order of execution of <strong>changeSets</strong>, see <a href="http://www.liquibase.org/documentation/changeset.html" rel="nofollow noreferrer">here</a>.</p>
  
  <p><strong>Does liquibase guarantee, that the changes are executed sequentially in the order that they appear?</strong></p>
