The 'Change status' specific form removed and now accessible from issue/show view with no additional request (click on 'Update' to show the form).
The 'Change issue status' permission is removed. To change the status, the user just needs to have either 'Edit' or 'Add note' permissions and some workflow transitions allowed.
