I don't think it was pushed as heavily as the change to 8.0 was because it's really only minor changes to wording, grammar, spelling, etc. So I don't think you'll have to really change much of anything in your current policies and procedures.

However as majoy mentioned above, it is the responsibility of the site to ensure they are following the current edition, so you should probably write and follow a procedure to ensure this is done. It could be something as simple as designating appropriate personnel in your facility (SQF Practitioner(s) and their backup(s), senior management, etc.) to register for the SQFI email newsletter (edition 8.1 was announced in their email newsletter in July), and for the SQF Practitioner to check the SQFI website quarterly for any further info or updates (this is what we do at our facility and it's always seemed satisfactory for auditors).
You can also sign up for their free Learning Lunch Webinars as well to stay on top of changes and other current issues. Their webinar that covered Edition 8.1 had the following info on a slide:
1) Published July 2nd
2) Implementation on September 2nd
3) Desk audits conducted prior to September 2nd can have a desk audit for edition 8.0 or 8.1
4) Surveillance audits will be conducted to the Code they were certified against
FYI - Edition 9.0 is being targeted for released the end of 2020.
