0.13.2 - September 09, 2015

• Private_key supplied for remote_actions is now used to auth correctly. private_key argument
  should be the contents of private key file (of user specified in username argument). (bug-fix)
• Last newline character ('\n') is now stripped from stdout and stderr fields in local
  and remote command/shell runners. (improvement)
• Fix sensor container service so the config argument is correctly passed to the sensor
  instances in the system packs. Previously, this argument didn't get passed correctly to the
  FileWatchSensor from the system linux pack. (bug-fix)
• Make sure sensor processes correctly pick up parent --debug flag. This makes debugging a lot
  easier since user simply needs to start sensor container with --debug flag and all the sensor
  logs with level debug or higher will be routed to the container log. (improvement)

0.13.1 - August 28, 2015

• cwd for paramiko script runner should use cwd provided as runner parameter. (bug-fix)
• Fix timer regression; bring brake broken timers. (bug-fix)
• Updates to trace objects are done via non-upsert updates by adding to the array. This makes it safer to update trace objects from multiple processes. (bug-fix)

0.13.0 - August 24, 2015

• Add new OpenStack Keystone authentication backend.
  [Itxaka Serrano]
• Information about parent workflow is now a dict in child's context field. (improvement)

  falsey value was used in the action metadata parameter override (e.g. False, 0).
  [Eugen C.]
• Correctly return 404 if user requests an invalid path which partially maps to an existing
  path. (bug-fix)
• Add support for restarting sensors which exit with a non-zero status code to
  the sensor container. Sensor container will now automatically try to restart
  (up to 2 times) sensor processes which die with a non-zero status code. (improvement)
• Support for RabbitMQ cluster. StackStorm works with a RabbitMQ cluster and switches
  nodes on failover. (feature)
• Add index to the ActionExecution model to speed up query. (improvement)
• Fix sort key in the ActionExecution API controller. (bug-fix)

• Make sure auth hook and middleware returns JSON and "Content-Type: application/json" header
  in every response. (improvement, bug-fix)
• Fix bug in triggers emitted on key value pair changes and sensor spawn/exit. When
  dispatching those triggers, the reference used didn't contain the pack names
  which meant it was invalid and lookups in the rules engine would fail. (bug-fix)
• Allow user to include files which are written on disk inside the action create API payload.
  (new feature)
• Allow user to retrieve content of a file inside a pack by using the new
  /packs/views/files/ API endpoint. (new feature)

  (bug-fix, improvement)
• Add X-Request-ID header to all API calls for easier debugging. (improvement)
• Add new CLI commands for disabling and enabling content pack resources
  ({sensor,action,rule} {enable, disable} <ref or id>) (feature)
