4.0.0
^^^^^


Prelude
*******

In this release, storlets project include various cleanup of the
internal protocol, in particular from short text to the json style and
the syntax. Those changes may affect to upgrade path on running
environment. Please see upgrade section in this release note.


Known Issues
************

* Python3 works are going forward but not yet completed so we should
  finish out it by the end of years. At least, py3-functional should
  pass on the gate.


Upgrade Notes
*************

* As you can see in prelude, storlets has been changing the internal
  protocol so you may get trouble if you would try to upgrade running
  cluster without downtime. For safety, you should stop the
  swift/storlets process in a node while upgrading. The upgrade should
  include re-compile of storlets java modules.


Bug Fixes
*********

* Other various minor bug fixes.
