Release 0.17.3

Major features and improvements

• Kedro plugins can now override built-in CLI commands.
• Added a before_command_run hook for plugins to add extra behaviour before Kedro CLI commands run.
• pipelines from pipeline_registry.py and register_pipeline hooks are now loaded lazily when they are first accessed, not on startup:

from kedro.framework.project import pipelines

print(pipelines["__default__"])  # pipeline loading is only triggered here

Bug fixes and other changes

• TemplatedConfigLoader now correctly inserts default values when no globals are supplied.
• Fixed a bug where the KEDRO_ENV environment variable had no effect on instantiating the context variable in an iPython session or a Jupyter notebook.
• Plugins with empty CLI groups are no longer displayed in the Kedro CLI help screen.
• Duplicate commands will no longer appear twice in the Kedro CLI help screen.
• CLI commands from sources with the same name will show under one list in the help screen.
• The setup of a Kedro project, including adding src to path and configuring settings, is now handled via the bootstrap_project method.
• configure_project is invoked if a package_name is supplied to KedroSession.create. This is added for backward-compatibility purpose to support a workflow that creates Session manually. It will be removed in 0.18.0.
• Stopped swallowing up all ModuleNotFoundError if register_pipelines not found, so that a more helpful error message will appear when a dependency is missing, e.g. Issue #722.
• When kedro new is invoked using a configuration yaml file, output_dir is no longer a required key; by default the current working directory will be used.
• When kedro new is invoked using a configuration yaml file, the appropriate prompts.yml file is now used for validating the provided configuration. Previously, validation was always performed against the kedro project template prompts.yml file.
• When a relative path to a starter template is provided, kedro new now generates user prompts to obtain configuration rather than supplying empty configuration.
• Fixed error when using starters on Windows with Python 3.7 (Issue #722).
• Fixed decoding error of config files that contain accented characters by opening them for reading in UTF-8.
• Fixed an issue where after_dataset_loaded run would finish before a dataset is actually loaded when using --async flag.

Upcoming deprecations for Kedro 0.18.0

• kedro.versioning.journal.Journal will be removed.
• The following properties on kedro.framework.context.KedroContext will be removed:
  • io in favour of KedroContext.catalog
  • pipeline (equivalent to pipelines["__default__"])
  • pipelines in favour of kedro.framework.project.pipelines
