1.1.0 - October 27, 2015

• Add YAQL v1.0 support to Mistral. Earlier versions are deprecated. (improvement)
• Update CLI so st2 run / st2 execution run and st2 execution re-run commands exit with
  non-zero code if the action fails. (improvement)
• Move st2auth service authentication backends to a "repo per backend" model. Backends are now also
  dynamically discovered and registered which makes it possible to easily create and use custom
  backends. For backward compatibility reasons, flat_file backend is installed And available by
  default. (new feature, improvement)
• New st2auth authentication backend for authenticating against LDAP servers -
  https://github.com/StackStorm/st2-auth-backend-ldap. (new feature)
• Default to rule being disabled if the user doesn't explicitly specify enabled attribute when
  creating a rule via the API or inside the rule metadata file when registering local content
  (previously it defaulted to enabled).
• Fix timestamp_lt and timestamp_gt filtering in the /executions API endpoint. Now we
  return a correct result which is expected from a user-perspective. (bug-fix)
• Enable Mistral workflow cancellation via st2 execution cancel. (improvement)
• Make sure that alias execution endpoint returns a correct status code and error message if the
  referenced action doesn't exist.
• Allow action-alias to be created and deleted from CLI.
• Allow user to select keystone backend in the st2auth service. (bug-fix)
• Fix packs.info action so it correctly exists with a non-zero status code if the pack doesn't
  exist or if it doesn't contain a valid .gitinfo file. (bug-fix)
• Fix packs.info action so it correctly searches all the packs base dirs. (bug-fix)
• Add support for --profile flag to all the services. When this flag is provided service runs
  in the profiling module which means all the MongoDB queries and query related profile data is
  logged. (new-feature)
• Introduce API Keys that do not expire like Authentication tokens. This makes it easier to work
  with webhook based integrations. (new-feature)
• Allow user to define trigger tags in sensor definition YAML files. (new feature) #2000
  [Tom Deckers]
• Fix a bug in stdout and stderr consumption in paramiko SSH runner where reading a fixed
  chunk byte array and decoding it could result in multi-byte UTF-8 character being read half way
  resulting in UTF-8 decode error. This happens only when output is greater than default chunk size
  (1024 bytes) and script produces utf-8 output. We now collect all the bytes from channel
  and only then decode the byte stream as utf-8.
• Update CLI so it supports caching tokens for different users (it creates a different file for each
  user). This means you can now use ST2_CONFIG_FILE option without disabling token cache.
  (improvement)
• Cleanup timers and webhook trigger definitions once all rules referencing them are removed. (bug-fix)
• Enable pseudo tty when running remote SSH commands with the paramiko SSH runner. This is done
  to match existing Fabric behavior. (bug-fix)
• Fix CLI so it skips automatic authentication if credentials are provided in the config on "auth"
  command. (bug fix)
• Strip the last '\r' or '\r\n' from both stdout and stderr streams from paramiko and local
  runner output. This is done to be compatible with fabric output of those streams. (bug-fix)
• Include parameters when viwewing output an execution on the CLI. (improvement)
• CLI renders parameters and output as yaml for better readability. (improvement)
• Set env variables (user provided and system assigned) before running remote command or script
  action with paramiko. (bug-fix)
• Fix a bug in Paramiko SSH runner where cwd could just be accessed in sudo mode but cd
  was outside scope of sudo in the command generated. Now, cd is inside the scope of
  sudo. (bug-fix)
• Fix a bug in Paramiko SSH runner where kwargs keys in script arguments were not shell
  injection safe. For example, kwarg key could contain spaces. (bug-fix)
• Fix a bug in Paramiko SSH runner where JSON output in stdout or stderr wasn't transformed
  to object automatically. (bug-fix)
• Paramiko SSH runner no longer runs a remote command with sudo if local user and remote user
  differ. (bug-fix)
• Fix a bug with the CLI token precedence - now the auth token specified as an environment variable
  or as a command line argument has precedence over credentials in the CLI config. (bug fix)
• Support versioned APIs for auth controller. For backward compatibility, unversioned API calls
  get redirected to versioned controllers by the server. (improvement)
• Add option to verify SSL cert for HTTPS request to the core.http action. (new feature)
• Update remote runner to include stdout and stderr which was consumed so far when a timeout
  occurs. (improvement)
• Fix st2-self-check script to check whether to use http/https when connecting to st2, to disable
  Windows test by default, and to check test status correctly. (bug-fix)
• Reduce the wait time between message consumption by TriggerWatcher to avoid latency (improvement)
• Use exclusive messaging Qs for TriggerWatcher to avoid having to deal with old messages
  and related migration scripts. (bug-fix)
• Allow user to specify value for the From field in the sendmail action by passing from
  parameter to the action. (improvement)
  [pixelrebel]
• Allow user to update / reinstall Python dependencies listed in requirements.txt inside the
  pack virtual environment by passing update=True parameter to packs.setup_virtualenv
  action or by using new packs.update_virtualenv action. (new feature)
  [jsjeannotte]
• Pack on install are now assigned an owner group. The pack_group property allows to pick this
  value and default is st2packs. (new feature)

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)
• Fix a bug when some runner parameter default values where not overridden when a
  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)
• Introduce a Paramiko SSH runner that uses eventlets to run scripts or commands in parallel. (improvement) (experimental)
• Add action parameters validation to Mistral workflow on invocation. (improvement)
• Fix key name for error message in liveaction result. (bug-fix)
• Fix 500 API response when rule with no pack info is supplied. (bug-fix)
• Fix bug in trigger-instance re-emit (extra kwargs passed to manager is now handled). (bug-fix)
• Rename notification "channels" to "routes". (improvement)
• 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)
• Handle sudo in paramiko remote script runner. (bug-fix)
• Turn on paramiko ssh runner as the default ssh runner in prod configuration.
  To switch to fabric runner, set use_paramiko_ssh_runner to false in st2.conf. (improvement)

• Update st2ctl to correctly start st2web even if even if Mistral is no installed.
  (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)
• Fix a bug in handling positional arguments with spaces. (bug-fix)
• Make sure that the $PATH environment variable which is set for the sandboxed Python
  process contains "/bin" directory as the first entry. (bug fix)

0.12.2 - August 11, 2015

• Support local ssh config file in remote runners. (feature)
• Changes to htpasswd file used in flat_file auth backend do not require a restart of st2auth and consequently StackStorm. (feature)

0.12.1 - July 31, 2015

• Un-registering a pack also removes rules and action aliases from the pack. (bug-fix)
• Disable parallel SSH in fabric runner which causes issues with eventlets. (bug-fix)

  support jinja (improvement)
• New experimental workflow runner based on the open-source CloudSlang project. (new-feature)
  [Eliya Sadan, Meir Wahnon, Sam Markowitz]
• Update all the code to handle all the datetime objects internally in UTC. (improvement,
  bug-fix)
• Allow users to use timediff_lt and timediff_gt rule comparison operator with many string
  date formats - previously it only worked with ISO8601 date strings. (improvement)
• Allow user to specify new secret attribute (boolean) for each action parameters. Values of
  parameters which have this attribute set to true will be masked in the log files. (new-feature)
• API server now gracefully shuts down on SIGINT (CTRL-C). (improvement)
• Fix a bug with with reinstalling a pack with no existing config - only try to move the config
  file over if it exists. (bug fix)
• Support for masking secret parameters in the API responses. Secret parameters can only be viewed
  through the API by admin users. (new-feature)
• Single sensor mode of Sensor Container uses --sensor-ref instead of --sensor-name.
