We have changed the update times for the last hint release on 7 Oct and the end of competition on 8 Oct to from 12:00 noon to 13:00 Australian Eastern Summer Time. This gives the usual 24 hours between changes, rather than the 23 hours that would occur if we stayed with the same local time across our Daylight Saving time shift. All updates are now at 02:00 GMT, rather than the previously advertised (and incorrect) 03:00 GMT for 7 and 8 Oct.
