the current download of the feedback 1.7 includes some bugfixes and changed behavior with using anonymous feedbacks.
- added two columns (random_response,anonymous_response) to feedback_complete and feedback_complete_tmp
- userids now will be logged even if the feedback is anonymous so you now can filter by group. However the anonymity will be preserved. More details can be viewed at: http://tracker.moodle.org/browse/MDL-9140
- excel-export now use pear so cell-values can be greater then 255 chars. However the issue with to many cellformats exists anymore. Here it helps to open the xls-file with OpenOffice
- the name of the first excel-worksheet now will be checked of wrong characters.
- logs now include the cm->id
- fixing the issue with using (') in text-responses
