[Samba] Book to learn new features since O'Reilly's 2007 "Using Samba, 3rd Edition"?

[Gilles]

Hello,

What book or good online resource in English 
<https://www.samba.org/samba/docs/> would you recommend to learn about 
what was added to Samba since the 3rd edition of O'Reilly's "Using 
Samba" came out in 2007?

The wiki <https://wiki.samba.org/index.php/Main_Page> is nice, but I 
like actual books because they're more structured.

Thank you.
