Changes

Features

• ✨ TEP-0108: Mapping Workspaces (TEP-0108: Mapping Workspaces #4887)

Users can specify the Workspace to use for PipelineTask in the name label to reduce verbosity when the names of the Workspaces declared in the Pipeline and PipelineTask are the same. Users can continue to explicitly map Workspaces.

• ✨ Add taskRef remote resolution support (Add taskRef remote resolution support #4859)

Allow taskRefs to be resolved directly from public git repos, using the tektoncd/resolution project.

• ✨ [TEP-0100] Add status helper functions for minimal embedded status ([TEP-0100] Add status helper functions for minimal embedded status #4850)

Added helper functions for retrieving full TaskRun and Run statuses when using embedded-status=minimal.

• ✨ TEP-0107: Implement Parameter Propagation (TEP-0107: Implement Parameter Propagation #4845)

Parameters are propagated in embedded specifications without mutations.

• ✨ TEP-0106: Support Specifying Metadata per Task in Runtime (TEP-0106: Support Specifying Metadata per Task in Runtime #4834)

Support Specifying Metadata per Task in Runtime (PipelineRun)

• ✨ [TEP-0075] Support Dictionary in Params ([TEP-0075] Support Dictionary in Params #4786)

Add support for dictionary in Params values (and Results as well). This should affect backward compatibilities but it will break forward compatibilities in some cases (a.k.a. old client with new pipeline version)
action required: This changes the ArrayOrStruct structure, which will have effect on project using the go API as a library.

• ✨ Extract full parameter name when using dots in bracket notation. (Extract full parameter name when using dots in bracket notation. #4880)

Extract full parameter name when using dots inside single/double quotes.

• ✨ Added validation for parameters with bracket notation (Added validation for parameters with bracket notation #4833)

Added validation for parameters with bracket notation

• ✨ TEP-0103: Skipping Reason - Add SkippingReason to SkippedTasks field of PipelineRunStatus (TEP-0103: Skipping Reason - Add SkippingReason to SkippedTasks field of PipelineRunStatus #4829)

Add SkippingReason to SkippedTasks field of PipelineRunStatus. This enables users to know the exact reason why a given PipelineTask was skipped.

• ✨ [TEP-0076] Add array support for emitting results ([TEP-0076] Add array support for emitting results #4818)

Support array type for emitting results from a task as an alpha feature.

The type of the result is changed from string to ArrayOrString.

A task can specify a type to produce array result, such as:

  results:
    - name: array-results
      type: array
      description: The array results

And the task script can populate result in an array form with:

echo -n "[\"hello\",\"world\"]" | tee $(results.array-results.path)

This feature is part of the TEP-0076 and its in progress to index into the array result while consuming that result.

• ✨ Add validation for duplicated param names in TaskSpec (Add validation for duplicated param names in TaskSpec #4806)

Add validation for duplicated param names in TaskSpec.

• ✨ [TEP-0076]Add type for results ([TEP-0076]Add type for results #4779)

Add Type for TaskRunResult and TaskResult.
