Release 4.0.6 - 2014/09/29
--------------------------

Improvements
^^^^^^^^^^^^

* [deb] Updated to follow the rule about machine-readable

  "between(X, 0, 'exclude', 100, 'include')" - "X > 0 && X <= 100".
* [doc] Changed to recommend GitHub for reporting issues.
  Until now, Redmine account must be approved by administrator, so you can not

  column isn't created.

Fixes
^^^^^

  for choosing target tokens.

* Fixed a crash bug when deleting a record.
  If the table of the record has ``_key`` and ``_key`` is
