7.1.0

New Features

• Add conditions_evaluation property to /queue/{queue_name}/pull/{pr_number} endpoint. This property contains a JSON tree with queue rule conditions evaluation.
• Queue action has a new option batch_max_failure_resolution_attempts corresponding to the number of attempts to resolve a batch failure before unqueueing pull requests. By default, Mergify will attempt to resolve a batch failure by splitting it. You can choose to stop this process after several splits.
• It is now possible to use some commit details in the conditions. Each commit can be accessed via its index and needs to be followed by the attribute you want to access, eg: commits[0].commit_message for the message of the first commit, commits[-1].date_committer for the last commit's date. The available attributes are author, commit_message, commit_verification_verified, committer, date_author, date_committer, email_author, email_committer. The operations available on each attribute depend on its type, you can refer to the documentation for more information.
• Add new /queue/{queue_name}/pull/{pr_number} endpoint to the API. This endpoint returns data from a queued pull request.
• The label action now has a new option called toggle. This option will add labels if the rule's conditions are a success and remove those if the rule's conditions fail.
• Mergify now allows to disable the cascading effect of a queue freeze through a new attribute named cascading available in /api/repos/<owner>/<repo>/queue/<queue_name>/freeze.
• Mergify now allows you to define priority_rules in the queue_rules configuration. priority_rules allows you to prioritize pull request treatment inside a queue based on your custom conditions.
• The rebase action will now rebase a PR, even if it has no commits behind, if the autosquash option is enabled.

Deprecation Notes

• Deprecate property speculative_check_pull_request in /queues API endpoint. This property is replaced by mergeability_check which is shorter. Details can be retrieved with new endpoint /queue/{queue_name}/pull/{pr_number}.
• The conditions attributes current-time, current-day-of-week, current-day, current-timestamp are deprecated in favor of the schedule attribute. The conditions attribute current-month, current-year are also being deprecated but do not have a replacement attribute.
• The priority configuration option of the merge action is deprecated and planned for removal.
• The environment variables MERGIFYENGINE_GITHUB_REST_API_URL and MERGIFYENGINE_GITHUB_GRAPHQL_API_URL are no longer required.
• The environment variables MERGIFYENGINE_BOT_USER_ID and MERGIFYENGINE_BOT_USER_LOGIN are no longer required.
• The rebase_fallback configuration option of the queue and merge actions is deprecated and planned for removal.

Bug Fixes

• Multiple pull_request_rules with the same name in the configuration will raise an error.
