What's Changed

This patch fixes a bug where environment variables were no longer passed to git since v4.0.0. For instance, this prevented the action to sign commits with GPG using variables like GNUPGHOME. With this fix, environment variables are provided to git again.

• fix: pass existing environment variables when executing git by @yafanasiev in #527

Full Changelog: v4.0.0...v4.0.1

What's Changed

Backport-action now detects when a backport branch or pull request already exists and continues without posting an error comment. This means you can safely add backport labels after a previous run. It also allows you to retry the workflow where the branch was pushed, but the pull request couldn’t be created. In earlier versions, rerunning in those situations would have left an error comment on the original pull request. Now, it handles these gracefully. The actions' log shows what happens in detail. Thanks @wolfgangwalther for this great contribution!

• Treat errors on repeated runs gracefully by @wolfgangwalther in #473

A typo in the actions' log was also fixed thanks to @codygarver.

• utils: fix typo in error message by @codygarver in #475

What's Changed

This release adds two new inputs: add_labels and add_author_as_assignee.

add_labels allows you to specify additional labels for the backport pull request. Thanks @chancez for the great contribution!

• Add support for statically setting labels on backport PRs by @chancez in #432
• Delimit add_labels using comma by @korthout in #454

add_author_as_assignee allows you to control whether the action should set the author of the original pull request as an assignee on the backport pull request. Thanks @soooch for the great contribution!

• Add option to add original author as assignee by @soooch in #445

Full Changelog: v3.1.0...v3.2.0

What's Changed

This release adds a new input source_pr_number that allows you to specify the pull request to backport in your workflow. Previously, the action always determined the pull request from the event payload, limiting the action only to backport the pull request associated with the current workflow run. This new input can be helpful in workflows that prefer to be explicit, workflows that run on workflow_dispatch events, and complex workflows that require flexibility. Thanks for this great contribution @chancez!

• Add source_pr_number input by @chancez in #434

Full Changelog: v3.0.2...v3.1.0

Fixed

This release fixes a small bug in the draft_commit_conflicts option for the experimental conflict_resolution feature. When encountering conflicts, the backport pull request is opened in draft mode with the conflicts committed. Instructions are provided to resolve these conflicts locally, but these were incorrect. For more details see #421.

• Checkout draft branch instead of target in suggestion by @korthout in #423
