+Notes for BIND 9.17.0
+---------------------
+
+Known Issues
+~~~~~~~~~~~~
+
+-  UDP network ports used for listening can no longer simultaneously be
+   used for sending traffic. An example configuration which triggers
+   this issue would be one which uses the same ``address:port`` pair for
+   ``listen-on(-v6)`` statements as for ``notify-source(-v6)`` or
+   ``transfer-source(-v6)``. While this issue affects all operating
+   systems, it only triggers log messages (e.g. "unable to create
+   dispatch for reserved port") on some of them. There are currently no
+   plans to make such a combination of settings work again.
+
+New Features
+~~~~~~~~~~~~
+
+-  When a secondary server receives a large incremental zone transfer
+   (IXFR), it can have a negative impact on query performance while the
+   incremental changes are applied to the zone. To address this,
+   ``named`` can now limit the size of IXFR responses it sends in
+   response to zone transfer requests. If an IXFR response would be
+   larger than an AXFR of the entire zone, it will send an AXFR response
+   instead.
+
+   This behavior is controlled by the ``max-ixfr-ratio`` option - a
+   percentage value representing the ratio of IXFR size to the size of a
+   full zone transfer. The default is ``100%``. [GL #1515]
+
+-  A new RPZ option ``nsdname-wait-recurse`` controls whether
+   RPZ-NSDNAME rules should always be applied even if the names of
+   authoritative name servers for the query name need to be looked up
+   recurively first. The default is ``yes``. Setting it to ``no`` speeds
+   up initial responses by skipping RPZ-NSDNAME rules when name server
+   domain names are not yet in the cache. The names will be looked up in
+   the background and the rule will be applied for subsequent queries.
+   [GL #1138]
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+-  The system-provided POSIX Threads read-write lock implementation is
+   now used by default instead of the native BIND 9 implementation.
+   Please be aware that glibc versions 2.26 through 2.29 had a bug_ that
+   could cause BIND 9 to deadlock. A fix was released in glibc 2.30, and
+   most current Linux distributions have patched or updated glibc, with
+   the notable exception of Ubuntu 18.04 (Bionic) which is a work in
+   progress. If you are running on an affected operating system, compile
+   BIND 9 with ``--disable-pthread-rwlock`` until a fixed version of
+   glibc is available. [GL !3125]
+
+.. _bug: https://sourceware.org/bugzilla/show_bug.cgi?id=23844
+
+-  The ``rndc nta -dump`` and ``rndc secroots`` commands now both
+   include ``validate-except`` entries when listing negative trust
+   anchors. These are indicated by the keyword ``permanent`` in place of
+   the expiry date. [GL #1532]
+
+Bug Fixes
+~~~~~~~~~
+
+-  Fixed re-signing issues with inline zones which resulted in records
+   being re-signed late or not at all.
