...ParamKeys. - Add support for NINFO, RKEY, RESINFO, WALLET, CLA and TA RR types. BUG FIXES: - Prepend -march to CFLAGS to fix architecture detection (NLnetLabs/nsd#372). - Fix propagation of implicit TTLs (NLnetLabs/nsd#375). - Fix detection of Westmere architecture by checking for CLMUL too. - Fix compilation on NetBSD (#233). - Fix reading specialized symbolic links (NLnetLabs/nsd#380). -------------- next part -------------- A non-text attachment was scrubbed...
