Changes from 0.9.5 to 0.9.8
===========================

* Added support for aborting automatically pending commands
  that never receives the reply (to avoid memory leaks).

  in rehash and closing the client connections if they were
  unconfigured in the rehash.

  must be provided when new key pair is created , and prompted
  when loading the private key.

* Resumed client packet handling from server put the resumed
  client on wrong list on router and caused the client not be
  present on the network anymore.

  many newlines in some situations.
