Maven users can update their project's pom.xml to reference the new core and plugin versions.
Ensure maven is configured to use the appropriate repository. Non-GA releases are usually available in a staging repositoryEnsure no dependencies in the freemarker groupId are used as the latest version used by Struts is now under the org.freeemarker groupId and will cause classpath conflicts.

If you need releases not considered General Availability you can use a staging repository where they are usually available:

<repositories>
    <repository>
      <id>struts2.1.2-staging</id>
      <name>Struts 2.1.2 staging repository</name>
      <layout>default</layout>
      <url>http://people.apache.org/builds/struts/2.1.2/m2-staging-repository/</url>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
    </repository>
  </repositories>
