Changes

Users can only edit bugs if they are the Assignee, the QA Contact, or are in the '''editbugs''' group. (Certain fields can also be edited by the Reporter. Also, all users can ''always'' comment and CC themselves on bugs.) However, note that by default, '''all users are in the editbugs group'''. If you want to change this default, go to Administration -> Groups, choose "editbugs" and clear the "userregexp" field. Then you can use Administration -> Users to explicitly add back certain users into the "editbugs" group, if you want them to be able to edit every field on every bug in the system. (Also, you can use Administration -> Product Products -> (select product) -> Group Controls to give groups of users "editbugs" for specific products.)
