...Message from Opera Team :
" We have today released a new security and stability update of Opera 11.6x
If you wonder why your Opera suddenly upgrade from 11.62 to 11.64 skipping 11.63 it´s because you are not on mac where we had to throw out a 11.63 release a short while back.
11.64 does not contain many bug fixes, but it is a recommended security update and it does fix some crashers and a bad nsl bug some people get on e.g Ebay."
