- adds some sort of CC functionality for notification
- allows sending emails with notifications to people who are not commit messages, or pr reviewers e.g project manager etc.
- when using the API and creating a comment with status change it's now possible to pass in
commit_id, this will allow validation if status change of pull_request is allowed based on the given
commit_id. This solves the case when long running test sends approval of pull request which was
already updated several times. The commit_id will now validate for which state the approval was made,
and prevent accidental aproval of outdated pull requests.
