   Hi everyone,
   after a long time, there is a new release of TN5250j now.
   There are a couple of useful bugfixes. Thanks to everyone,
   who supported us.
   The internal cope page conversion was rewritten, which was
   an important step to support Hebrew characters (CP-424).
   As of this version 0.7.0, TN5250j requires a Java 6 runtime.
   Supporting older versions of Java needs more effort, thus
   the older code branch is considered as deprecated.
   There was not much development during the last months, but it's
   time to release the existing bugfixes, now :-)
   Regards
   Martin
