getProcessElement() not found when migrating to Ivy 6

Hello,

While testing migration of various projects to Ivy 6.0, I encountered a problem with a method that does not exist anymore.

  /** 
   * Find the current process name. 
   * 
   * @return fully qualified process name 
   * @throws Exception 
   */ 
    public static String getName() throws Exception {
        return SecurityManagerFactory.getSecurityManager().executeAsSystem(new Callable<String>() {
            public String call() {
                IProcess process = ProcessNavigationUtil.getProcess(MetaData.getProcessElement());

                if (process != null) 
                    return process.getPath();

                return null;
            }
        });
    }

In the previous code, the method MetaData.getProcessElement() is not found. By looking in Ivy 5.1.7, it was implemented as:

  public static ZObject getProcessElement()
  {
    return (ZObject)IvyThreadContext.getIvyThreadLocalValue("processElement");
  }

Now the method has been removed, and a new method getProcessElementId() was added, but with a new signature:

  public static PID getProcessElementId()
  {
    return (PID)IvyThreadContext.getIvyThreadLocalValue("processElement");
  }

I didn't found this change in the migration documentation. Can I know the reason for removing the previous method and what are the alternative in order to get the current process name? Thanks.
