TestComplete Plugin 2.11 not working with Jenkins 2.581

The TestComplete Support Jenkins plugin (TcTestBuilder) requires the Apache Commons Lang 2.x library (class org.apache.commons.lang.StringUtils) at runtime. Unfortunately, since our Jenkins installation was updated to the latest version, our tests no longer run because this library was deprecated and has now been removed. The call stack then shows, for example:

13:10:18 FATAL: org/apache/commons/lang/StringUtils
13:10:18 java.lang.ClassNotFoundException: org.apache.commons.lang.StringUtils
13:10:18 Caused: java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils
13:10:18 at PluginClassLoader for TestComplete//com.smartbear.jenkins.plugins.testcomplete.TcTestBuilder.makeCommandLineArgs(TcTestBuilder.java:1299)

When can we expect the new version of the TestComplete plugin? I hope very soon... Downgrading Jenkins is out of the question for us.
