Security Fixes
+ BIND 9 nameservers performing recursive queries could cache an
invalid record and subsequent queries for that record could
crash the resolvers with an assertion failure. [RT #26590]
[CVE-2011-4313]
Feature Changes
+ RPZ implementation now conforms to version 3 of the specification.
[RT #27316]
+ It is now possible to explicitly disable DLV in named.conf by
specifying "dnssec-lookaside no;". This is the default, but the
ability to configure it makes it clearly visible to administrators.
[RT #24858]
+ --enable-developer, a new composite argument to the configure
script, enables a set of build options normally disabled but
frequently selected in test or development builds, specifically:
enable_fixed_rrset, with_atf, enable_filter_aaaa, enable_rpz_nsip,
enable_rpz_nsdname, and with_dlz_filesystem (and on Linux and
Darwin, also enable_exportlib) [RT #27103]
