row no. 1356, column 243:
Similar to the issue which allowed teachers to create site-wide scales by editing a course-specific scale (<a class="text" href="http://tracker.moodle.org/browse/<a class="text" href="http://tracker.moodle.org/browse/MDL-24682">MDL-24682</a>">MDL-24682</a>), teachers could also promote a course-specific scale to a site-wide (standard) by editing it.  As with MDL-24682, removing the course ID check (leaving just the capability check) prevents this unauthorised creation of site-wide (standard) outcomes.<br/>

Marked as possible security issue, because without changelog nobody knows if something security related has been changed. The changelog shouldn't be not wellformed either.

Maybe the changelog descriptions itself could also be improved, because I don't think many people immediately know what Merge branch ... of ... really changed/fixed without looking into the details?
