--- 9.6-ESV-R4-P3 released ---
3124. [bug] Use an rdataset attribute flag to indicate
negative-cache records rather than using rrtype 0;
this will prevent problems when that rrtype is
used in actual DNS packets. [RT #24777]
--- 9.6-ESV-R4-P2 released (withdrawn) ---
3123. [security] Change #2912 exposed a latent flaw in
dns_rdataset_totext() that could cause named to
