Custom bug statuses are for creating a customized bug workflow specific to the project. Project owners and users with permission to configure project settingd can create custom bug statuses.
Navigate to Settings in the projects primary horizontal menu, then to Bug Statuses in the secondary horizontal menu. Click Add Custom Status. It is required to add a name for a new custom bug status, and it must be mapped to a system defined status (Blocked, Closed, Deferred, Duplicate, Fixed, In Progress, Not a bug, Open). Adding a description for the custom bug status is optional. Click Save to add the custom bug status.
To make a custom bug status usable within the project, the custom bug status must be associated with a bug type that has been added to the project.
