0.17.0
======
Additions
---------
- Add required_vars option to Workflows to ensure that required variables
are set before the workflow is executed.
- Integrate required_vars into CLI.
0.16.0
======
Additions
---------
- Add ``and_finally`` option to the Group (and derived) nodes. This provides a way
to execute nodes to clean up after a workflow has completed successfully or
an exception was raised.
Changes
-------
- testing.call_node now accepts a workflow context. This allows for inspection
of the context if an exception is raised.
- Fix the inheritance of exceptions. All RunTime exceptions are now based off
of ``WorkflowRuntimeError``.
- ``TryExcept`` now resolves nodes called after an exception taking subclasses
into account. This matches the behaviour of Python itself.
0.15.0
======
Additions
---------
- Add TryExcept node to handle errors in a workflow.
Changes
-------
- ForEach node now shows each loop and allows for custom labels
for each loop.
- Improve indentation of workflow output.
0.14.0
======
Additions
---------
- Add FeatureEnabled node to enable/disable a feature based on a
PyApp feature-flag.
0.13.0
======
Additions
---------
- Add Group. A group is a set of nodes that are executed but do not
get placed in a new variable scope. Useful for building blocks of
nodes.
- Group also includes an option to change the log_level for the duration
of the group being executed.
- Fatal step has been added to trigger a fatal exception to stop the
workflow.
Changes
-------
- Nodes now inherits from Group and includes the log_level option.
0.12.0
======
Additions
---------
- Add TryUntil node for trying multiple nodes until one succeeds.
Changes
-------
- Add log-level helpers
- Include that flowfile.py is located on in the workflow context.
- Use var name to reference workflow from CLI.
- Fetch version from package info.
- Added tracing support to aid in debugging workflows.
- Add flowfile.py support for execution of workflows in a repository.
0.11.0
======
Changes
-------
- Format output of Workflow name to format from the context.
- Added a skip_step function, that allows a step to be skipped. This is based
off an exception that is handled by the Step class wrapping the function.
0.10.0
======
Changes
-------
- Support pyApp constructs
0.9.0
