The previous release promised reduced memory footprint from refactored RDATA storage (and it did for the vast majority of cases), but just after the release, we received a report that NSD was consuming more memory for specific kind of zones (with RRsets consisting of many RRs). This release will have that addressed so that NSD now consumes less memory in all cases and circumstances. A blog post highlighting these memory reductions will be posted with the actual release (next week).

Other than that, this release contains bug fixes, among others some that emerged with the new RDATA storage code from the previous release.
