I fixed a typo in the documentation ("is" is now "if") for the new XenoBank-sponsored notthere_ip parameter.
I also have run the SQA regressions against the code, including the new test for the notthere_ip parameter. The new test had a bug which I have fixed by using a simple Perl script. Note that this now requires Perl to run the SQA tests; I think I will make the baseline for MaraDNS testing "CentOS 5.2", since it's stable (it will be updated until March 31, 2014) and since I have a portable VMware player image of this OS.
It can be downloaded at the usual place (Do I have to remind you that is a clickable link?)
