Yep:

(Speaking of the faq, it looks like the issue in question 43 can be
resolved by adding "recurse_delegation = 1" to one's mararc file.)

Let us know if you have any issues.  There are a few very unusual
cases that would cause problems (I went to a lot of work to minimize
these issues), but usually all you have to do is just update the
binary.  I have documented all changes:

Thank you very much for using MaraDNS; it makes my resume look more
impressive when notable places like Medline use MaraDNS.
