Create Environments on Release via a PR Label in Github
This setting integrates with GitHub's labeling features so that you can create environments in Release by adding labels to pull requests in GitHub. You can customize this label at the account level in account settings or at the application level as shown below.
A label set here will override any label set in the account settings for this app.
If you have set a Github label name in application settings and applied the label to a PR, Release will make a new environment for this application.
Remove a label set at the application level by erasing the text from the line and clicking save.
