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
+ Improves initial start-up and server reload time by increasing
the default size of the hash table the configuration parser
uses to keep track of loaded zones and allowing it to grow
dynamically to better handle systems with large numbers of
zones. [RT #26523]
+ --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]
