[Astrid Emde]

Hello developer,

Therefore we have to update the Version history.

Christoph, Uli could you please have a look mat the history and add the 
new features.

Check wether the new tools are documented. If not, please send a mail, 
so that we can find a person to do the documentation.


The comment in the history can be short. Arnulf and me will write a more 
detailed release note for the mailing list.
