Ym mis Hydref a Thachwedd 2014, cadarnhawyd fy ymrwymiad i gyhoeddi canllawiau diwygiedig ac, bryd hynny, dywedais hefyd y byddai dogfen ddiwygiedig ar gael yng ngwanwyn 2015.
In October and November 2014 I reaffirmed my commitment to issue revised guidance and at that time indicated that an amended document would be available in spring 2015.
