FreeBSD Handbook (PDF) - update for 13.0?

Hi,

I recently discovered that the non-html versions of the handbook seen to be somewhat out of date.

To be specific:
All files in https://download.freebsd.org/ftp/doc/en/books/handbook/ show a last modify date of January 24, 2021 - well before FreeBSD 13 came out. As per "Abstract" they cover "...installation and day to day use of FreeBSD 12.2-RELEASE, Free-BSD 12.1-RELEASE, and FreeBSD 11.4-RELEASE..."

Does anybody out there know why the non-HTML-versions of the handbook weren't updated for FreeBSD 13.x and/or when they will be availble?

Thanks much in advance for any clue,
