+- Fixes a bug in test case BASIC01 that made tests of zones
+  fail if, while walking the chain of delegations from the root to the
+  zone under test, a name server returns a referral pointing to name
+  servers for an intermediate zone which are all out-of-bailiwick and
+  lacking glue. The bug was introduced in version v4.7.0 in release
+  v2023.1. (#1282)
+- Disable blacklisting for queries by NAMESERVER15 to prevent false
+  errors and warnings (#1285)
