title: How to rollback database with liquibase
body: <p>I am using in my project liquibase for database migration.</p>
  
  <p>I have this dependency in my pom:</p>
  
  <pre><code>    &lt;dependency&gt;
          &lt;groupId&gt;org.liquibase&lt;/groupId&gt;
          &lt;artifactId&gt;liquibase-core&lt;/artifactId&gt;
      &lt;/dependency&gt;
  </code></pre>
  
  <p>and in application.properties this property:</p>
  
  <pre><code>spring.liquibase.change-log=classpath:/db/changelogs/changelog-master.xml
  </code></pre>
  
  <p>I am developing new task and I created few changesets with adding and renaming columns of tables, and now I found some mistake and I need change these changesets but at first I need rollback them.</p>
  
  <p>Can you tell me how to do that?</p>
