0.9

• moving from Travis to Github Actions for CI
• fixing issues with numpy.arrays provided as input fields
• adding a combiner option for dotfiles and graphs plots
• refactoring the input classes (adding FunctionSpec)
• adding MultiInpObj and MultiOutObj for a possible types in input/output_spec
• fixing copyfile_workflow
• setting proper Workflow.output_spec using tasks' output_specs
• setting output_dir as a parent directory for all files created using the output templates
• adding requires key to output_spec's metadata in order to set conditions for creating a specific output field
• adding input_spec and output_spec as class attributes that could be rewritten in the init or in the child classes

0.8

• refactoring template formatting for input_spec
• fixing issues with input fields with extension (and using them in templates)
• adding simple validators to input spec (using `attr.validator)
• adding create_dotfile for workflows, that creates graphs as dotfiles (can convert to other formats if dot available)
• adding a simple user guide with input_spec description
• expanding docstrings for State, audit and messanger
• updating syntax to newer python

0.7

• refactoring the error handling by padra: improving raised errors, removing nodes from the workflow graph that can't be run
• refactoring of the input_spec: adapting better to the nipype interfaces
• switching from pkg_resources.declare_namespace to the stdlib pkgutil.extend_path
• moving readme to rst format

0.6.1

• Add pydra.tasks namespace package to enable separate packages of Tasks to be installed into pydra.tasks.
• Raise error when task or workflow name conflicts with names of attributes, methods, or other tasks already added to workflow
• Mention requirements.txt in README

0.6

• removing the tutorial to a separate repo
• adding windows tests to codecov
• accepting None as a valid output from a FunctionTask, also for function that returns multiple values
• fixing slurm error files
• adding wf._connection to checksum
• allowing for updates of wf._connections
• editing output, so it works with numpy.arrays
• removing to_job and pickling task instead (workers read the tasks and set the proper input, so the multile copies of the input are not kept in the memory)
• adding standalone function load_and_run that can load and run a task from a pickle file
• removing create_pyscript and simplifying the slurm worker
• improving error reports in errors flies
• fixing make_class so the Output is properly formatted

0.5

• fixing hash_dir function
• adding get_available_cpus to get the number of CPUs available to the current process or available on the system
• adding simple implementation for BoshTask that uses boutiques descriptor

• adding an experimental implementation of Dask Worker (limited testing with ci)

0.4

• reorganization of the State class, fixing small issues with the class
• fixing some paths issues on windows os
• adding osx and window sto the travis runs (right now allowing for failures for windows)
• adding PydraStateError for exception in the State class
• small fixes to the hashing functions, adding more tests
• adding hash_dir to calculate hash for Directory type

0.3.1

• passing wf.cache_locations to the task
• using rerun from submitter to all task
• adding test_rerun and propagate_rerun for workflows
• fixing task with a full combiner
• adding cont_dim to specify dimensionality of the input variables (how much the input is nested)
