v1.5.0

Fixed

• Update jinja to use sandboxed environment. (bug fix)
• Optimise inspect and workflow graph generation logic. (improvement)
  Contributed by @yogeshgoyal26

v1.4.0

Changed

• Migrate from Travis to Github Actions. (improvement)

Fixed

• Fix unreachable join when an inbound task fails as defined in the task transition. (bug fix)
• Throw exception if the workflow definition that is written in YAML contains duplicate keys
  (i.e. task name). (bug fix)

v1.3.0

Added

• Implement the orquesta-rehearse command to run unit tests for workflow. (new feature, beta)
  Contributed by AJ (guzzijones)

Changed

• Remove mistral fixtures because they were used as ref to support multiple specs. Mistral is
  deprecated in StackStorm and there's no intention to support it here. A mistral to orquesta
  workflow conversion tool is available at https://github.com/StackStorm/orquestaconvert.

Fixed

• Fix the custom flake8 extensions to check import statements. (bug fix)
• Fix the deprecation warning that flags are not at the start of the expression. (bug fix)

v1.2.0

Changed

• Run pep8 and docs in tox with python3.
• Use black https://pypi.org/project/black/ for code formatting.
• Update tox to return error if there are uncommitted schema changes.

Fixed

• Warn users when there is a loop and no start task identified. (bug fix)
• Lock global variables during initialization to make them thread safe. (bug fix)
• Workflow stuck in running if one or more items failed in a with items task. (bug fix)
• Fix use case where a failed with items task is run again if the task is in a cycle. (bug fix)

v1.1.1

Fixed

• Fix task retry where transition on error is also executed along with retry. (bug fix)

v1.1.0

Added

• Add feature to retry task execution on given condition with delay in between retries and
  max number of retries. (new feature)
  Contributed by Hiroyasu Ohyama (@userlocalhost) and Nick Maludy (@nmaludy)
• Add support to rerun completed workflow (failed or succeeded) from given task(s). (new feature)

Changed

• Replace "noop" with "continue" when "do" is not specified. The new "continue" command
  will not alter the previous task state and will continue to conduct the workflow
  execution. StackStorm/st2#4740 (improvement)
• Refactor conductor to not store each item result in task state. If there are a lot of items
  and/or result size is huge per item, then there will be a performance impact on database
  write operations when recording the conductor state. (improvement)
• Use ujson to deepcopy dict(s) for faster performance. (improvement)
• Refactor how inbound criteria for join task is evaluated to count by task completion
  instead of task transition. (improvement)

Fixed

• Fix conducting of cycle with a fork. Fixes #169 (bug fix)
• Fix request_workflow_status to ignore certain status change errors such as pausing a workflow
  that is already pausing and canceling a workflow that is already canceling. (bug fix)
• Remove rendering of workflow output automatically when updating task state. This caused
  workflow output to render incorrectly in certain use case. The render_workflow_output function
  must be called separately. (bug fix)
• When inspecting custom YAQL/Jinja function to see if there is a context arg, use getargspec
  for py2 and getfullargspec for py3. (bug fix)
• Check syntax on with items task to ensure action is indented correctly. Fixes #184 (bug fix)
• Fix variable inspection where ctx().get() method calls are identified as errors.
  Fixes StackStorm/st2#4866 (bug fix)
• Fix a problem of TypeError orccuring when a list (or dict) value that contains unhashable typed
  value (list or dict) is passed in some YAQL operators (e.g. distinct()). Fixes #176 (bug fix)
  Contributed by Hiroyasu Ohyama (@userlocalhost)

v1.0.0

Changed

• Change the version number to the semver format and from 0.6 -> 1.0.0 to indicate GA.
• Rephrased the error message for the unreachable join task. Fixes #162 (improvement)

Fixed

• Allow tasks in the same transition with a "fail" command to run. (bug fix)
• Fix Jinja block expression to render correctly. (bug fix)

v0.5

Added

• Add flake8 extension to restrict import alias. (improvement)
• Add developer docs on getting started, testing, and StackStorm integration. (improvement)

Changed

• Refactor concept of task flow to workflow and task state. (improvement)
• Restrict ctx function from returning internal vars. (improvement)

Fixed

• Fix conductor performance for complex workflow definition. (bug fix)
• Fix overwritten context variables on task join. (bug fix)
• Fix with items task stuck in running when item(s) failed. (bug fix)
• Fix task status for various scenarios on with item task. (bug fix)
• Fix return value of item that evaluate to false. (bug fix)
• Fix workflow stuck in resuming when pending task has transition error. (bug fix)

v0.4

Added

• Add get_routes function to workflow graph to identify possible execution routes. (new feature)
• Add ascii art diagrams to docs to illustrate workflows with join task. (improvement)

Fixed

• Add sleep in while loop for composing execution graph to spread out cpu spike. (improvement)
• Value in quotes in shorthand publish should be evaluated as string type. Fixes #130 (bug fix)
• Fix interpretation of boolean value in shorthand format of publish. Fixes #119 (bug fix)
• Update YAQL section in docs on use of "=>" for named parameters in function calls. Closes #124
• Fix with items intepretor to handle variables that contain the word 'in'. (bug fix)
