@marko.hakamaa,
Back in November 2016 OMB posted a copy of the “Predecisional Draft” SF86 at https://www.reginfo.gov/public/do/PRAViewIC?ref_nbr=201306-3206-005&icID=44214. The most important change is the new wording for Question 21, which was approved by ODNI on the same day the draft SF86 was released. US District Courts haven’t issued Naturalization Certificates in well over 10 years (ever since INS moved from the Justice Department to Homeland Security and became USCIS); nevertheless, the SF86 continues to ask for the name and location of the court that issued the certificate.
