Every change is indicated by a system note in the issue's or merge request's comments.
### Indications of locked issues or merge requests
While you are inside the locked issue or merge request and you are a project team member you can see an indicator in the comment form that the issue or merge request is locked.
If you are not a team member you won't see the comment form but only the information that the dicussion is locked.
