  • v2.8.1 Changes

    July 18, 2018

    ➕ Added

    
* ⚡️ Update ``st2`` CLI to inspect ``COLUMNS`` environment variable first when determining the
  terminal size. Previously this environment variable was checked second last (after trying to
  retrieve terminal size using various OS specific methods and before falling back to the default
  value).

  This approach is more performant and allows user to easily overwrite the default value or value
  returned by the operating system checks - e.g. by running ``COLUMNS=200 st2 action list``.
  (improvement) #4242

🔄 Changed
    • ⚡️ Update st2client/setup.py file to dynamically load requirements from st2client/requirements.txt file. The code works with pip >= 6.0.0, although using pip 9.0.0 or higher is strongly recommended. (improvement) #4209
    • 🏗 Migrated runners to using the in-requirements.txt pattern for "components" in the build system, so the Makefile correctly generates and installs runner dependencies during testing and packaging. (improvement) (bugfix) #4169

    Contributed by Nick Maludy (Encore Technologies).

    • ⚡️ Update st2 CLI to use a more sensible default terminal size for table formatting purposes if we are unable to retrieve terminal size using various system-specific approaches.

    Previously we would fall back to a very unfriendly default of 20 columns for a total terminal width. This would cause every table column to wrap and make output impossible / hard to read. (improvement) #4242

    🛠 Fixed

    
* 🛠 Fixed a bug where ``secret: true`` was not applying to full object and array trees. (bugfix) #4234
  Reported by @jjm

  Contributed by Nick Maludy (Encore Technologies).
* Mark ``password`` ``http-request`` parameter as a secret. (bug fix) #4245

  Reported by @daniel-mckenna

  • v2.8.0 Changes

    July 10, 2018

    ➕ Added

    
* Orquesta - new StackStorm-native workflow engine. This is currently in **beta**. (new feature)
* ➕ Added metrics for collecting performance and health information about the various ST2 services
  and functions. (new feature) #4004 #2974
* 🚀 When running a dev (unstable) release include git revision hash in the output when using
  ``st2 --version`` CLI command. (new feature) #4117
* ⚡️ Update rules engine to also create rule enforcement object when trigger instances fails to match
  a rule during the rule matching / filtering phase due to an exception in the rule criteria (e.g.
  invalid Jinja expression, etc.).

  This change increases visibility into rules which didn't match due to an exception. Previously
  this was only visible / reflected in the rules engine log file. (improvement) #4134
* ➕ Add new ``GET /v1/ruleenforcements/views[/<enforcement id>]`` API endpoints which allow user to
  retrieve RuleEnforcement objects with the corresponding TriggerInstance and Execution objects.
  (new feature) #4134
* ➕ Add new ``status`` field to the ``RuleEnforcement`` model. This field can contain the following
  values - ``succeeded`` (trigger instance matched a rule and action execution was triggered
  successfully), ``failed`` (trigger instance matched a rule, but it didn't result in an action
  execution due to Jinja rendering failure or other exception). (improvement) #4134 #4152
* ➕ Add trigger type reference based filtering to the ``/v1/triggerinstances`` API endpoint - e.g.
  ``/v1/triggerinstances?trigger_type=core.st2.webhook``. (new feature) #4151
* ➕ Add new ``--python3`` flag to ``st2 pack install`` CLI command and ``python3`` parameter to
  ``packs.{install,setup_virtualenv}`` actions. When the value of this parameter is True, it
  uses ``python3`` binary when creating virtual environment for that pack (based on the value of
  ``actionrunner.python3_binary`` config option).

  Note 1: For this feature to work, Python 3 needs to be installed on the system, ``virtualenv``
  package installed on the system needs to support Python 3 (it needs to be a recent version) and
  pack in question needs to support Python 3.

  Note 2: This feature is experimental and opt-in. (new feature) #4016 #3922 #4149
* ➕ Add two new Jinja filters - ``basename`` (``os.path.basename``) and ``dirname``
  (``os.path.dirname``). #4184

  Contributed by Florian Reisinger (@reisingerf).

🔄 Changed
    • ⚡️ Update st2 CLI to create the configuration directory and file, and authentication tokens with secure permissions (eg: readable only to owner) #4173
    • 🔨 Refactor the callback module for the post run in runner to be more generic. (improvement)
    • ⚡️ Update various Python dependencies to the latest stable versions (gunicorn, gitpython, python-gnupg, tooz, flex). #4110
    • ⚡️ Update all the service and script entry points to use /etc/st2/st2.conf as a default value for the config file location.

    This way users don't need to explicitly provide --config-file CLI argument when running various scripts (e.g. st2-track-result, st2-apply-rbac-definitions, etc.) and when they just want to use a default config file. (improvement) #4111

    • ⚡️ Update st2 CLI to print a warning if a non-unicode system locale which would prevent StackStorm to function correctly in some scenarios is used. (improvement) #4127 #4120
    • ⬆️ Upgrade various internal Python library dependencies to the latest stable versions (kombu, amqp, gitpython, pytz, semver, oslo.utils). (improvement) #4162
    • 🚚 Move from keyczar library to cryptography library for handling symmetric encryption and decryption (secret datastore values).

    Note: This change is fully backward compatible since it just changes the underlying backend and implementation details. The same underlying encryption algorithm is used (AES256 in CBC mode with HMAC signature). (improvement) #4165

    🛠 Fixed

    
* 🛠 Fixed a bug where secrets in pack configs weren't being masked. Recently we
  introduced support for nested objects and arrays. Secret parameters within these
  nested objects and arrays were not being masked. The fix involves us fully
  traversing deeply nested objects and arrays and masking out any variables
  marked as secret. This means we now support pack config JSON schemas with
  ``type: object`` and its corresponding ``parameters: {}`` stanza, along with
  ``type: array`` and its corresponding ``items: {}`` stanza. We still do NOT
  support JSON schema combinations that includes the ``anyOf``, ``allOf``,
  ``oneOf``, and ``not`` keywords. (bug fix) #4139

  Contributed by Nick Maludy (Encore Technologies).
* 💅 Style clean up to transport queues module and various config modules. (improvement)
* 🛠 Fixed CLI help for ``st2 action-alias match`` and ``execute``. (#4174).
* 🛠 Fix regression in ``?include_attributes`` query param filter in the ``/v1/executions`` API
  endpoint. (bug fix) #4226

  • v2.7.2 Changes

    May 16, 2018

    🔄 Changed

    
* ⬇️ Reduce load on LDAP server and cache user groups response in an in-memory cache when RBAC
  remote LDAP group to local RBAC role synchronization feature is enabled.

  Previously on authentication the code would hit LDAP server multiple times to retrieve user
  groups. With this change, user LDAP groups are only retrieved once upon authentication and
  cached and re-used in-memory by default for 120 seconds.

  This reduces load on LDAP server and improves performance upon regular and concurrent user
  authentication.

  This functionality can be disabled by setting ``cache_user_groups_response`` LDAP
  authentication backend kwarg to ``false``.

  Note: This change only affects users which utilize RBAC with remote LDAP groups to local RBAC
  roles synchronization feature enabled. (enterprise) (bug fix) #4103 #4105

🛠 Fixed
~~~~~

* 🛠 Fix an issue (race condition) which would result in not all the remote LDAP groups being
  synchronized with local RBAC roles if a user tried to authenticate with the same auth token
  concurrently in a short time frame.

  Note: This issue only affects users which utilize RBAC with remote LDAP groups to local RBAC
  roles synchronization feature enabled. (enterprise) (bug fix) #4103 #4105
* 🛠 Fix an issue with some sensors which rely on ``select.poll()`` (FileWatch, GithubSensor, etc.)
  stopped working with StackStorm >= 2.7.0.

  StackStorm v2.7.0 inadvertently introduced a change which broke a small set of sensors which
  rely on ``select.poll()`` functionality. (bug fix) #4118

* Throw if ``id`` CLI argument is not passed to the ``st2-track-result`` script. (bug fix) #4115
* 🛠 Fixed pack config's not properly rendering Jinja expressions within lists. (bugfix) #4121

  Contributed by Nick Maludy (Encore Technologies).
* 🛠 Fixed pack config rendering error throw meaningful message when a Jinja syntax error is
  encountered. (bugfix) #4123

  Contributed by Nick Maludy (Encore Technologies).

  • v2.7.1 Changes

    April 20, 2018

    🔄 Changed

    
* When creating a pack environment during the pack installation, we now pass ``--no-download`` flag
  to the ``virtualenv`` binary. This way version of pip, wheel and distutils which is enforced by
  virtualenv is used instead of downloading the latest stable versions from PyPi.

  This results in more reproducible pack virtual environments and we also ensure pip 9.0 is used (
  there are some known issues with pip 10.0).

  If for some reason you want to revert to the old behavior, you can do that by passing
  ``no_download=False`` parameter to the ``packs.setup_virtualenv`` action. #4085

🛠 Fixed
~~~~~

* 🛠 Fix ``st2 pack search`` and ``POST /api/v1/packs/index/search`` API endpoint so it doesn't
  return internal server error when a single pack search term is provided. (bug fix) #4083

  • v2.7.0 Changes

    April 12, 2018

    ➕ Added

    
* ⚡️ Update ``st2 execution tail`` command so it supports double nested workflows (workflow ->
  workflow -> execution). Previously, only top-level executions and single nested workflows
  (workflow -> execution) were supported. (improvement) #3962 #3960
* ➕ Add support for utf-8 / unicode characters in the pack config files. (improvement) #3980 #3989

  Contributed by @sumkire.
* ➕ Added the ability of ``st2ctl`` to utilize environment variables from ``/etc/default/st2ctl``
  (for Ubuntu/Debian) and ``/etc/sysconfig/st2ctl`` (RHEL/CentOS). This allows
  deployments to override ``COMPONENTS`` and ``ST2_CONF`` in a global location
  so ``st2ctl`` can start/stop/restart selected components and utilize a non-default
  location for ``st2.conf``.
  (new feature) #4027

  Contributed by Nick Maludy (Encore Technologies).
* ➕ Add support for new optional ``content_version`` runner parameter to the Python and Local Shell
  Script runner. This parameter can contain a git commit hash / tag / branch from a pack git
  repository and runner will ensure this revision of the pack content (Python action / local shell
  script action) is used for a particular action execution.

  Keep in mind that providing this parameter only ensures a particular revision of the pack content
  is used. Python runner virtual environment and dependencies are outside of this scope.

  Note: To be able to utilize this functionality, git version >= 2.5.0 must be installed on the
  system.
  (new feature) #3997
* ⚡️ Update windows runner to correctly handle and use ``timeout`` action execution status.
  (improvement) #4047
* ➕ Add missing ``scope``, ``decrypt`` and ``encrypt`` arguments to the datastore management
  related methods on the SensorService class. (improvement) #3895 #4057 #4058

  Reported by @djh2020, @mxmader.
* ➕ Add context field to rule model in which each rule has its own corresponding user. Besides, there
  is a new RBAC configuration ``permission_isolation``. Whoever can only operate and observe their
  own rules or executions except ``system_user`` and users with RBAC admin role when set to
  ``True``. That means system_user has the most powerful permission to operate all resources
  including rules or executions. (new feature) #4013

  Contributed by Hanxi Liu (@apolloliu).

🔄 Changed
    • Modified RabbitMQ connection error message to make clear that it is an MQ connection issue. #3992
    • ➕ Additional refactor which makes action runners fully standalone and re-distributable Python packages. Also add support for multiple runners (runner modules) inside a single Python package and consolidate Python packages from two to one for the following runners: local runners, remote runners, windows runners. (improvement) #3999
    • ⬆️ Upgrade eventlet library to the latest stable version (0.22.1) (improvement) #4007 #3968
    • Increase maximum retry delay for action.retry policy from 5 seconds to 120 seconds. Because of the way retries are currently implemented (they are not st2notifier service restart safe), long retry delays are not recommended. For more information on this limitation please refer to the documentation - https://docs.stackstorm.com/reference/policies.html#retry. #3630 #3637
    • ⚡️ Update Python runner so it throws a more user-friendly exception in case Python script tries to access a key in self.config dictionary which doesn't exist. (improvement) #4014
    • ⚡️ Update various Python dependencies to the latest stable versions (apscheduler, gitpython, pymongo, stevedore, paramiko, tooz, flex, webob, prance).
    • 🔨 Refactored mistral runner to support callback from mistral instead of relying on st2resultstracker. This reduces the unnecessary traffic and CPU time by querying the mistral API. Included a command to manually add a state entry for Mistral workflow execution to recover from any callback failures. (improvement)
    • Throw a more user-friendly error when writing pack data files to disk and when an invalid file path is provided (e.g. path is outside the pack directory, etc.). (improvement) #4039 #4046
    • 🔄 Change the output object returned by Windows runners so it matches the format from the local and remote runner.

    Note: This change is backward incompatible - result attribute has been removed (same information is available in stdout attribute), exit_code renamed to return_code and two new attributes added - succeeded and failed.

    For more information, please refer to the upgrade notes. #4044 #4047

    🛠 Fixed

    
* 🛠 Fix Python runner actions and ``Argument list too long`` error when very large parameters are
  passed into the action. The fix utilizes ``stdin`` to pass parameters to the Python action wrapper
  process instead of CLI argument list. (bug fix) #1598 #3976
* 🛠 Fix a regression in ``POST /v1/webhooks/<webhook name>`` API endpoint introduced in v2.4.0
  and add back support for arrays. In 2.4.0 support for arrays was inadvertently removed and
  only objects were supported. Keep in mind that this only applies to custom user-defined
  webhooks and system ``st2`` webhook still requires input to be an object (dictionary).
  (bug fix) #3956 #3955
* 🛠 Fix a bug in the CLI causing ``st2 execution pause`` and ``st2 execution resume``
  to not work. (bugfix) #4001

  Contributed by Nick Maludy (Encore Technologies).
* 🛠 Fixed missing "paused" status option from "st2 execution list" help output. (bugfix) #4037

  Contributed by Ben Hohnke (NTT Communications ICT Solutions)
* 🛠 Fix "st2 pack install" command so it doesn't require access to pack index (index.stackstorm.org)
  when installing a local pack (pack name starting with "file://"). (bug fix) #3771 #3772
* 🛠 Fix rules engine so it correctly handles and renders action parameters which contain Jinja
  expressions and default values. (bug fix) #4050 #4050

  Reported by @rakeshrm.
* 👉 Make sure ``observer`` system role also grants ``pack_search`` permission. (bug fix) #4063 #4064

  Reported by @SURAJTHEGREAT.
* 🛠 Fix st2 webhook get -h which was asking for a name or id as opposed to the URL of the webhook.
  Also, fix st2 webhook list to explicitly add a webhook column. (bugfix) #4048
* 🛠 Fix an issue with pack config validation code throwing a non-user friendly error message in case
  config item of type array failed config schema validation. (bug fix) #4166 #4168

  Reported by @NikosVlagoidis.

  • v2.6.0 Changes

    January 19, 2018

    ➕ Added

    
* 👉 Add new ``get_user_info`` method to action and sensor service. With this method, user can
  retrieve information about the user account which is used to perform datastore operations inside
  the action and sensor service. (new feature) #3831
* ➕ Add new ``/api/v1/user`` API endpoint. This API endpoint is only available to the authenticated
  users and returns various metadata on the authenticated user (which method did the user use to
  authenticate, under which username the user is authenticated, which RBAC roles are assignment to
  this user in case RBAC is enabled, etc.) (new feature) #3831
* The ``/api/v1/match_and_execute`` API endpoint matches a single alias and executes multiple times
  if the alias format has a ``match_multiple`` key set to ``true``. Please refer to the
  documentation for usage. #3884

  Contributed by @ahubl-mz.
* ➕ Add ability to share common code between python sensors and python actions. You can now place
  common code inside a ``lib`` directory inside a pack (with an ``__init__.py`` inside ``lib``
  directory to declare it a python package). You can then import the common code in sensors and
  actions. Please refer to documentation for samples and guidelines. #3490
* ➕ Add support for password protected sudo to the local and remote runner. Password can be provided
  via the new ``sudo_password`` runner parameter. (new feature) #3867
* ➕ Add new ``--tail`` flag to the ``st2 run`` / ``st2 action execute`` and ``st2 execution re-run``
  CLI command. When this flag is provided, new execution will automatically be followed and tailed
  after it has been scheduled. (new feature) #3867
* ➕ Added flag ``--auto-dict`` to ``st2 run`` and ``st2 execution re-run`` commands. This flag must now
  be specified in order to automatically convert list items to dicts based on presence of colon
  (``:``) in all of the list items (new feature) #3909
* 👍 Allow user to set default log level used by all the Python runner actions by setting
  ``actionrunner.pythonrunner```` option in ``st2.conf`` (new feature) #3929
* ⚡️ Update ``st2client`` package which is also utilized by the CLI so it also works under Python 3.

  Note: Python 2.7 is only officially supported and tested Python version. Using Python 3 is at
  your own risk - they are likely still many bugs related to Python 3 compatibility. You have been warned.
  (new feature) #3929 #3932

  Contributed by Anthony Shaw.
* ➕ Add ``?limit=-1`` support for the API to fetch full result set (CLI equivalent flag
  ``--last/-n``). Post error message for ``limit=0`` and fix corner case where negative values for
  limit query param were not handled correctly. #3761 #3708 #3735
* Only allow RBAC admins to retrieve all the results at once using ``?limit=-1`` query param, upate
  the code so ``api.max_page_size`` config option only applies to non-admin users, meaning users
  with admin permission can specify arbitrary value for ``?limit`` query param which can also be
  larger than ``api.max_page_size``. (improvement) #3939
* ➕ Add new ``?include_attributes`` query param filter to ``/v1/executions/`` API endpoint
  With this filter user can select which fields to include in the response (whitelist approach,
  opposite of the existing ``?exclude_attributes`` filter).

  For example, if you only want to retrieve ``id`` and ``status`` field, the URL would look like
  this - ``/v1/executions?include_attributes=id,status``. (new feature) #3953 #3858 #3856

🔄 Changed
    • st2actions.runners.pythonrunner.Action class path for base Python runner actions has been deprecated since StackStorm v1.6.0 and will be fully removed in StackStorm v2.7.0. If you have any actions still using this path you are encouraged to update them to use st2common.runners.base_action.Action path. #3803
    • 🔨 Refactor st2common Python package so it's fully self sustaining and can be used in a standalone manner. (improvement) #3803
    • 🔨 Refactor Python action runner so it only depends on st2common Python package (previously it also depended on st2actions) and can be used in a standalone mode. Previously pack config and and some other parameters were retrieved inside the Python process wrapper, but now they are retrieved inside the runner container and passed to the runner. This also makes it easier to add support for pack configs to other runners in the future. (improvement) #3803
    • ⚡️ Update various Python dependencies to the latest stable versions (kombu, amqp, apscheduler, gitpython, pymongo, stevedore, paramiko, prompt-toolkit, flex). #3830
    • Mask values in an Inquiry response displayed to the user that were marked as "secret" in the inquiry's response schema. #3825
    • 0️⃣ Real-time action output streaming is now enabled by default. For more information on this feature, please refer to the documentation - https://docs.stackstorm.com/latest/reference/action_output_streaming.html. You can disable this functionality by setting actionrunner.stream_output config option in st2.conf to False and restart the services (sudo st2ctl restart).

    🛠 Fixed

    
* 🐎 Fully fix performance regressions for short Python runner actions introduced in the past and
  partially fixed in #3809. (bug fix) #3803
* 🛠 Fix 'NameError: name 'cmd' is not defined' error when using ``linux.service`` with CentOS systems.
  #3843. Contributed by @shkadov
* 🛠 Fix bugs with newlines in execution formatter (client) (bug fix) #3872
* 🛠 Fixed ``st2ctl status`` to use better match when checking running process status. #3920
* ✂ Removed invalid ``st2ctl`` option to re-open Mistral log files. #3920
* ⚡️ Update garbage collection service and ``st2-purge-executions`` CLI tool and make deletion more
  efficient. Previously we incorrectly loaded all the execution fields in memory, but there was no
  need for that and now we only retrieve and load id which is the only field we need. #3936

  Reported by @kevin-vh.

  • v2.5.1 Changes

    December 14, 2017

    ➕ Added

    
* ➕ Add new ``log_level`` runner parameter to Python runner. With this parameter, user can control
  which log messages generated by Python runner actions are output to action ``stderr``. For
  backward compatibility reasons it defaults to ``debug``.
  This functionality comes handy in situations when an action depends on an external library which
  logs a lot of information under ``debug``, but you only want to see messages with log level
  ``error`` or higher (or similar). (new feature) #3824
* ➕ Add stevedore related metadata to Python package setup.py files for runner packages. This way
  runners can be installed using pip and dynamically enumerated and loaded using stevedore and
  corresponding helper functions.

  All runners are now also fully fledged Python packages (previously they were single module
  Python packages which caused various install and distribution related issues when installing
  them via pip) (new feature)
* ➕ Add new ``search`` rule criteria comparison operator. Please refer to the documentation for
  usage. (new feature) #3833

  Contributed by @ahubl-mz.
* Now a more user-friendly error message is thrown if a cycle is found inside the Jinja template
  string (e.g. when parameter / variable references itself). (improvement) #3908
* 0️⃣ Jinja templates in default parameter values now render as live parameters, if no "real" live
  parameter was provided. This allows the template to render pre-schema validation, resulting
  in the intended value type. (improvement) #3892

🔄 Changed
    • ⚡️ Update the output of st2 execution {run,get} CLI command to colorize the value of the status attribute (green for succeeded, red for failed, etc. aka the same as for the output of st2 execution list command). (improvement) #3810

    Contributed by Nick Maludy (Encore Technologies).

    • ⚡️ Update log messages in the datastore service to correctly use DEBUG log level instead of AUDIT. #3845
    • ➕ Add the ability of st2 key load to load keys from both JSON and YAML files. Files can now contain a single KeyValuePair, or an array of KeyValuePairs. (improvement) #3815
    • ➕ Add the ability of st2 key load to load non-string values (objects, arrays, integers, booleans) and convert them to JSON before going into the datastore, this conversion requires the user passing in the -c/--convert flag. (improvement) #3815
    • ⚡️ Update st2 key load to load all properties of a key/value pair, now secret values can be loaded. (improvement) #3815

    Contributed by Nick Maludy (Encore Technologies).

    🛠 Fixed

    
* 🛠 Fix log messages generated by Python runner actions to include the correct action class name.
  Previously they always incorrectly used "ABCMeta" instead of the actual action class name.
  (bug fix) #3824
* 🛠 Fix ``st2 execution tail [last]`` CLI command so it doesn't throw an exception if there are no
  executions in the database. (bug fix) #3760 #3802
* 🛠 Fix edge case for workflows stuck in running state. When Mistral receives a connection error from
  the st2 API on requesting action execution, there's a duplicate action execution stuck in
  requested state. This leads to the st2resultstracker assuming the workflow is still running.
* 🛠 Fix a regression and a bug with no API validation being performed and API returning 500 instead
  of 400 status code if user didn't include any request payload (body) when hitting POST and PUT
  API endpoints where body is mandatory. (bug fix) #3864
* 🛠 Fix a bug in Python runner which would cause action log messages to be duplicated in action
  stderr output when utilizing action service / datastore service inside actions. (bug fix)
* 🛠 Fix performance issue on the CLI when formatting the output as JSON or YAML. (bug fix) #3697

  Contributed by Nick Maludy (Encore Technologies).

  • v2.5.0 Changes

    October 25, 2017

    ➕ Added

    
* ➕ Add new feature which allows runner action output (stdout and stderr) to be streamed
  and consumed in real-time by using one of the following approaches:

  - ``/v1/executions/<execution id>/output[?type=stdout/stderr]`` API endpoint.
  - ``/v1/stream/`` stream endpoint and listening for ``st2.execution.stdout__create`` and
    ``st2.execution.output__create`` ``/v1/stream`` stream API endpoint events.
  - ``st2 execution tail <execution id> [--type=stdout/stderr]`` CLI command (underneath it uses
    stream API endpoint).

  Right now this functionality is available for the following runners:

  - local command runner
  - local script runner
  - remote command runner
  - remote script runner
  - python runner

  Note: This feature is still experimental and it's disabled by default (opt-in). To enable it,
  set ``actionrunner.stream_output`` config option to ``True``.

  (new feature) #2175 #3657 #3729
* ⚡️ Update ``st2 role-assignment list`` RBAC CLI command to include information about where a
  particular assignment comes from (from which local assignment or mapping file). (improvement)
  #3763
* ➕ Add support for overlapping RBAC role assignments for assignments via remote LDAP group to
  StackStorm role mappings. This means that the same role can now be granted via multiple RBAC
  mapping files.
  #3763
* Add new Jinja filters ``from_json_string``, ``from_yaml_string``, and ``jsonpath_query``.
  #3763
* ➕ Add new "Inquiry" capability, which adds ability to "ask a question", usually in a workflow.
  Create a new runner type: "inquirer" to support this, as well as new API endpoints and
  client commands for interacting with Inquiries

  Contributed by mierdin. #3653
* ➕ Added two new rule operators, ``inside`` and ``ninside`` which allow for the reverse intent of
  the ``contains`` and ``ncontains`` operators. #3781

  Contributed by @lampwins.
* 👍 Allow user to use more expressive regular expressions inside action alias format string by
  allowing them to specify start (``^``) and end (``$``) anchors. Previously, those anchors were
  automatically added at the beginning and end of the alias format string. Now they are only added
  if a format string doesn't already contain them. #3789

  Contributed by @ahubl-mz.
* Add new ``POST /v1/aliasexecution/match_and_execute`` API endpoint which allows user to
  schedule an execution based on a command string if a matching alias is found in the database.

  This API endpoint is meant to be used with chat bot plugins. It allows them to be simple thin
  wrappers around this API endpoint which send each chat line to this API endpoint and handle the
  response. #3773
* ➕ Add several improvements to the installation scripts: They support using proxy servers.
  ``~stanley`` no longer has to be ``/home/stanley``. In addition to the on-screen display, the
  output from the installation script is now logged to a file beginning with ``st2-install`` under
  ``/var/log/st2/``. Furthermore, the script handles re-runs better, although it's
  not fully idempotent yet. More improvements are expected in the near future.
  st2-packages: #505, #506, #507, #508, #509, #510, #512, #517.

🛠 Fixed
    • 🛠 Fix a bug where sensor watch queues were not deleted after sensor container process was shut down. This resulted in spurious queues left behind. This should not have caused performance impact but just messes with rabbitmqadmin output and maybe tedious for operators. (bug fix) #3628

    Reported by Igor.

    • 👉 Make sure all the temporary RabbitMQ queues used by the stream service are deleted once the connection to RabbitMQ is closed. Those queues are temporary and unique in nature and new ones are created on each service start-up so we need to make sure to correctly clean up old queues.

    #3746

    • 🛠 Fix cancellation of subworkflow and subchain. Cancel of Mistral workflow or Action Chain is cascaded down to subworkflows appropriately. Cancel from tasks in the workflow or chain is cascaded up to the parent. (bug fix)
    • 🛠 Fix delays in st2resultstracker on querying workflow status from Mistral. Make sleep time for empty queue and no workers configurable. Reduce the default sleep times to 5 seconds. StackStorm instances that handle more workflows should consider increasing the query interval for better CPU utilization.
    • 🛠 Fix missing type for the parameters with enum in the core st2 packs.(bug fix) #3737

    Reported by Nick Maludy.

    • ➕ Add missing -h / --help CLI flag to the following execution CLI commands: cancel, pause, resume. (bug fix) #3750
    • 🛠 Fix execution cancel and pause CLI commands and make id a required argument. (bug fix) #3750
    • 🛠 Fix st2 role-assignment list CLI command and allow --user, --remote and --role arguments to be used together. Previously they were mutually exclusive so it wasn't possible to use them together. (bug fix) #3763
    • ⚡️ Update default event name whitelist for /v1/stream API endpoint and make sure st2.announcement__errbot and other event names starting with st2.announcement__* prefix are not filtered out. #3769 (bug fix)

    Reported by Carlos.

    • 🛠 Fix action-alias execute response to show execution id and matching action-alias #3231 (bug fix) Reported by Carlos.
    • 🛠 Fix st2 apikey load command to update an existing entry if items in input file contain id attribute and item already exists on the server. This way the behavior is consistent with st2 key load command and the command is idempotent if each item contains id attribute. #3748 #3786

    Reported by Christopher Baklid.

    • 🌲 Don't log MongoDB database password if user specifies URI for database.db_host config parameter and that URI also includes a password. Default and a common scenario is specifying password as a separate database.password config parameter. #3797

    Reported by Igor Cherkaev.

    • 🛠 Fix POST /v1/actionalias/match API endpoint to correctly return a dictionary instead of an array. We had a correct OpenAPI definition for the response, but the code incorrectly returned an array instead of a dictionary.

    Note: This is a breaking change so if your code utilizes this API endpoint you need to update to treat response as a dictionary and not as an array with a single item. #377

    • 🐎 Partially fix performance overhead and regression for short and simple Python runner actions. Full / complete fix will be included in v2.6.0. #3809

    🔄 Changed

    
* 💅 Minor language and style tidy up of help strings and error messages. #3782

  • v2.4.1 Changes

    September 12, 2017

    🛠 Fixed

    
* 🛠 Fix a bug with ``/v1/packs/install`` and ``/v1/packs/uninstall`` API endpoints incorrectly using
  system user for scheduled pack install and pack uninstall executions instead of the user which
  performed the API operation.(bug fix) #3693 #3696

  Reported by theuiz.
* 🛠 Fix mistral callback failure when result contains unicode. (bug fix)
* 🛠 Fix cancellation of delayed action execution for tasks in workflow. (bug fix)
* 🛠 Fix timeout of mistral shutdown in systemd service. The fix is done upstream.
  https://review.openstack.org/#/c/499853/ (bug fix)
* 🛠 Fix ``st2ctl clean`` not using database connection information from config.
  This now uses the new ``st2-cleanup-db`` command. (bug fix) #3659

  Contributed by Nick Maludy (Encore Technologies).

🔄 Changed
    • ⚡️ Update st2 CLI command to print a more user-friendly usage / help string if no arguments are passed to the CLI. (improvement) #3710
    • 👍 Allow user to specify multiple values for a parameter of type array of dicts when using st2 run CLI command. #3670

    Contributed by Hiroyasu OHYAMA.

    • ➕ Added new command st2-cleanup-db that drops the current StackStorm MongoDB database. #3659

    Contributed by Nick Maludy (Encore Technologies).

  • v2.4.0 Changes

    August 23, 2017

    ➕ Added

    
* Add sample passive sensor at ``contrib/examples/sensors/echo_flask_app``. (improvement) #3667
* ➕ Add pack config into action context. This is made available under the ``config_context`` key.
  #3183
* ➕ Add limit/``-n`` flag and pagination note(stderr) in the CLI for ``st2 key list``.
  Default limit is 50. #3641
* Implement pause and resume for Mistral workflow and Action Chain. Pause and resume will cascade
  down to subworkflows and/or subchains. Pause from a subworkflow or subchain will cascade up to
  the parent workflow. (new feature)
* ➕ Add pack index endpoint. It will make a request for every index defined in st2.conf and return
  the combined list of available packs.
* ➕ Added a new field ``timestamp_f`` to the GELF logging formatter that represents
  the time of the logging even in fractional time (resolution is dependent on your
  system). This allows adjacent logging events to be distinguished more accurately
  by the time they occurred.
  Contributed by Nick Maludy (Encore Technologies) #3362
* Require new ``STREAM_VIEW`` RBAC permission type to be able to view ``/v1/stream`` stream API
  endpoint. (improvement) #3676
* Add new ``?events``, ``?action_refs`` and ``?execution_ids`` query params to ``/v1/stream/``
  API endpoint. These query parameters allow users to filter out which events to receive based
  on the event type, action ref and execution id. By default, when no filters are provided, all
  events are returned. (new feature) #3677
* 👉 Show count of pack content (actions, sensors, triggers, rules and aliases) to be registered
  before the ``st2 pack install`` so that the delay in install is not mistaken as no response
  or hanging command. (improvement) #3586 #3675
* 👍 Allow users to specify value for "array of objects" parameter type using a simple notation
  when using the ``st2 run`` CLI command. (improvement) #3646 #3670

  Contributed by Hiroyasu OHYAMA.
* Copy nearly all existing Jinja filters and make them available in both Jinja and YAQL within
  Mistral workflows (https://github.com/StackStorm/st2mistral/pull/30). Modify st2kv default
  behavior (BREAKING CHANGE) to not decrypt ciphertext in datastore by default (now explicitly
  enabled via optional parameter).

  Contributed by mierdin. #3565
* ➕ Add ``regex_substring`` Jinja filter for searching for a pattern in a provided string and
  returning the result. (improvement)

  Contributed by mierdin. #3482

🔄 Changed
    • 📇 Rename ST2 action runner cancel queue from st2.actionrunner.canel to st2.actionrunner.cancel. (improvement) #3247
    • 📚 Install scripts and documentation have been updated to install MongoDB 3.4 by default (previously 3.2 was installed by default). If you want to upgrade an existing installation, please follow the official instructions at https://docs.mongodb.com/v3.4/release-notes/3.4-upgrade-standalone/. (improvement)
    • ⚡️ Update garbage collector service to delete corresponding stdout and stderr objects which belong to executions which are to be deleted. #2175 #3657

    ✂ Removed

    
* 👌 Support for pack ``config.yaml`` has been removed. Pack configuration should use the new
  style, at ``/opt/stackstorm/configs/<pack>.yaml``. Packs containing ``config.yaml`` will generate
  a fatal ERROR on pack registration.

🛠 Fixed
~~~~~

* 🛠 Fix retrying in message bus exchange registration. (bug fix) #3635 #3638

  Reported by John Arnold.
* 🛠 Fix message bus related race condition which could, under some rare scenarios, cause first
  published message to be ignored because there were no consumers for that particular queue yet.
  This could happen in a scenario when API service came online and served a request before action
  runner service came online.

  This also fixes an issue with Redis kombu backend not working. (bug fix) #3635 #3639 #3648
* 🛠 Fix logrotate configuration to delete stale compressed st2actionrunner logs #3647
* Fix trace list API endpoint sorting by ``start_timestamp``, using ``?sort_desc=True|False`` query
  parameters and by passing ``--sort=asc|desc`` parameter to the ``st2 trace list`` CLI command.
  Descending order by default.(bug fix) #3237 #3665
* 🛠 Fix pack index health endpoint. It now points to the right controller. #3672
* 🛠 Fix 'pack register content' failures appearing on some slower systems by lifting action timeout.
