v11.4.6...v12.0.0

v12 Enhanced Commands, Outputs and Examples

Highlights (view blog)

• Around 55% reduction in codebase by consolidating action.yml within Bash, lowering the barrier to entry for contributors.
• Configurable rendering of command inputs and outputs without wrapper script (e.g., hide-args from PR comment).
• Streamlined documentation with a focus on workflow examples for common use-cases.

Breaking

• In/output parameters have been renamed:
  • All _ underscores are replaced with - hyphens.
  • working-directory is added as an alias to arg-chdir.
  • arg_command is renamed to command.
  • For the full list, view the parameters.
• To minimize dependencies, the following have been removed:
  • Tool installation via tenv (replacement).
  • Caching integration (replacement).

Added

• gh GitHub CLI integration for consistent interoperability with GitHub's REST API.
• Link to view workflow log with the precise step where TF-via-PR was executed.
• Pass repeated arguments as comma-separated values (e.g., arg-var: key1=value1,key2=value2).
• Contextual workflow outputs, like plan file artifact ID and URL, as well as truncated results from CLI response.

Updated

• Order of command execution to: fmt* > init > workspace* > validate* > plan/apply (* optional).
• Workflow examples with recommendations, including cron-scheduled configuration drift checks.
• comment-pr default from "recreate" to "update" for its revision history.
• format default from "true" to "false" for explicit opt-in of the command, as done with validate.

Removed

• actions/cache dependency, as out-of-scope.
• actions/github-script dependecy, as superseded by gh GitHub CLI.
• tenv dependency, as replaced by 3rd parties.

Fixed

• Upon failure, output the error message directly instead of the entire command output.
• Upon exceeding character limit, gracefully handle truncation of command output.
• Handling of multiline strings with associated quoting.

Secured

• Support for v12 and after.
