• SSL support for mongodb connections. (improvement)
• TriggerInstances now have statuses to help track if a TriggerInstance has been processed,
  is being processed or failed to process. This bring out some visibility into parts of the
  TriggerInstance processing pipeline and can help identify missed events. (new-feature)
• Allow user to enable service debug mode by setting system.debug config file option to
  True.
  Note: This is an alternative to the existing --debug CLI flag which comes handy when running
  API services under gunicorn. (improvement)
• Fix for data is dropped if message is not present in notification. (bug-fix)
• Remove now deprecated Fabric based remote runner and corresponding
  ssh_runner.use_paramiko_ssh_runner config option. (cleanup)
• Fix support for password protected private key files in the remote runner. (bug-fix)
• Allow user to provide a path to the private SSH key file for the remote runner private_key
  parameter. Previously only raw key material was supported. (improvement)
• Add new API endpoint and corresponding CLI commands (st2 runner disable <name>,
  st2 runner enable <name>) which allows administrator to disable (and re-enable) a runner.
  (new feature)
• Add RBAC support for runner types API endpoints. (improvement)
• Allow register-setup-virtualenvs flag to be used in combination with register-all in the
  st2-register-content script.
• Add get_fixture_content method to all the base pack resource test classes. This method
  enforces fixture files location and allows user to load raw fixture content from a file on disk.
  (new feature)
  future, pack configs will be validated against the schema (if available). (new feature)
• Add data model and API changes for supporting user scoped variables. (new-feature, experimental)
• Add missing pytz dependency to st2client requirements file. (bug-fix)
• Fix datastore access on Python runner actions (set ST2_AUTH_TOKEN and ST2_API_URL env
  variables in Python runner actions to match sensors). (bug-fix)
• Remove support for JSON format for resource metadata files. YAML was introduced and support for
  JSON has been deprecated in StackStorm v0.6. Now the only supported metadata file format is YAML.
• Add -y / --yaml flag to the CLI list and get commands. If this flag is provided,
  command response will be formatted as YAML. (new feature)
• Alias names are now correctly scoped to a pack. This means the same name for alias can be used
  across different packs. (bug-fix)
• Ability to migrate api keys to new installs. (new feature)
• Introduce a new concept of pack config schemas. Each pack can now contain a
  config.schema.yaml file. This file can contain an optional schema for the pack config. In the
• Introduce support for pack configs which are located outside of the pack directory in
  /opt/stackstorm/configs/<pack name>.yaml files. Those files are similar to the existing pack
  configs, but in addition to the static values they can also contain dynamic values. Dynamic value
  is a value which contains a Jinja expression which is resolved to the datastore item during
  run-time. (new feature)
• Fix a regression in filtering rules by pack with CLI. (bug-fix)
• Make sure st2-submit-debug-info cleans up after itself and deletes a temporary directory it
  creates. (improvement) #2714
  [Kale Blankenship]
• Fix string parameter casting - leave actual None value as-is and don't try to cast it to a
  string which would fail. (bug-fix, improvement)
• Allow administrator user who's context will be used when running an action or re-running an
  action execution. (new feature)
• Add a work-around for trigger creation which would case rule creation for CronTrigger to fail
  under some circumstances. (workaround, bug-fix)
• Store action execution state transitions (event log) in the log attribute on the
  ActionExecution object. (new feature)
• Make sure -a all / --attr=all flag works for st2 execution list command (bug-fix)
• Lazily establish SFTP connection inside the remote runner when and if SFTP connection is needed.
  This way, remote runner should now also work under cygwin on Windows if SFTP related
  functionality (file upload, directory upload, etc.) is not used. (improvement)

• API and CLI allow rules to be filtered by their enable state. (improvement)
• Fix SSH bastion host support by ensuring the bastion parameter is passed to the paramiko ssh
  client. (bug-fix) #2543 [Adam Mielke]
• Send out a clear error message when SSH private key is passphrase protected but user fails to
  supply passphrase with private_key when running a remote SSH action. (improvement)
• Admins will now be able pass --show-secrets when listing api keys to get the key_hash
  un-masked on the CLI. (new-feature)
• Add --register-triggers flag to the st2-register-content script and st2ctl.
  When this flag is provided, all triggers contained within a pack triggers directory are
  registered, consistent with the behavior of sensors, actions, etc. This feature allows users
  to register trigger types outside the scope of the sensors. (new-feature) [Cody A. Ray]
