I have released a new snapshot of MaraDNS today that fixes a problem with RFC4074 section 4.2 compliance. I have also backed off on the changes to the recursive code's memory allocation; it's time to completely rewrite the code to not use so many threads, and stop wasting time making changes to a codebase I won't be using once the recursor is rewritten.
The snapshot can be downloaded here:
