WordPress 4.9 Update

My WordPress dashboard notified me that a new version is available changing from 4.8.3 to 4.9 . I was afraid a another update would mess up Atahualpa. However it works GREAT!

My menu bar down arrows disappeared with version 4.8.3 but now they are back. It might be my imagination but it seems to run a bit faster too. I have not found any issues so far. Just thought I would pass this info along to those like me that are still using this theme.
