She didn’t release anything. She just stamped “approved” on the standard waiver form that Obama sent in, which is required when someone requests their birth certificate be released to a third party.
Loretta Fuddy did take personal credit for doing a bit more than just that:

If the News Release from 2011 is to be believed, she was THE key figure in Hawaii in approving and supplying what ended up on the whitehouse.gov web site and what was supplied to the media at Obama’s April 27, 2011 media event announcing his long form. The mainstream media totally backed off the eligibility story and investigations after that day. Even reporter Les Kinsolving of worldnetdaily who had been the primary member of the White House press corps to ask questions stopped asking after April 27th.
