BIND 9.12 is out!
We had to hold onto this over the recent holiday period, while we were waiting for a window to publish a reported vulnerability and circulate patched versions. Finally, now we are able to post the BIND 9.12 final.
9.12 has new features (NSEC Aggressive use, Serve Stale, Response Policy Service Interface), updates to cryptography and improved performance (dramatic improvement for glue-heavy scenarios). We refactored several of the more complex, error-prone functions and removed obsolete features. Before upgrading a production system, please read the release notes, as we have also changed some default settings.
