I have been using standard edition v8.1.0 and can report these observations:
Project Settings → Include Footer: set this to false and the footer gets included anyway. This was working in v7.1.2
Footer copyright year says 2022… I don’t see a way to change this.
Calendar widget is missing the record id/binding field and doesn’t render on the page. This was working in v7.1.2
HTML (Summernote) editor doesn’t render when selected for textareas. This was working in v7.1.2
Edit Page View → Edit Page CSS capability has been removed. This was handy for adding custom CSS to an individual page.
