+BIND 9.18.34
+------------
+
+New Features
+~~~~~~~~~~~~
+
+- Print the expiration time of the stale records. ``f04168545d1``
+
+  Print the expiration time of the stale RRsets in the cache dump.
+  :gl:`!10062`
+
+Removed Features
+~~~~~~~~~~~~~~~~
+
+- Remove --with-tuning=small/large configuration option. ``327b666c6d0``
+
+  The configuration option --with-tuning has been removed as it is no
+  longer required or desired. :gl:`!9959`
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- Reduce memory sizes of common structures. ``008e5201098``
+
+  * Reduce `sizeof(isc_sockaddr_t)` from 152 to 48 bytes * Reduce
+  `sizeof(struct isc__nm_uvreq)` from 1560 to 560 bytes
+
+  Partial backport of !8299 :gl:`!9953`
+
+- Refactor reference counting in RBTDB. ``fd9a85addc4``
+
+  Clean up the pattern in the newref() and decref() functions in RBTDB
+  databases.
+
+  Related to #5134 :gl:`!10036`
+
+- Shutdown the fetch context after canceling the last fetch.
+  ``57187b2c4f4``
+
+  Shutdown the fetch context immediately after the last fetch has been
+  canceled from that particular fetch context. :gl:`!9960`
+
+Bug Fixes
+~~~~~~~~~
+
+- Fix "rndc flushname" for longer name server names. ``b7383e50484``
+
+  :option:`rndc flushname` did not work for name server names longer
+  than 16 bytes. This has been fixed. :gl:`#3885` :gl:`!10025`
+
+- Recently expired records could be returned with timestamp in future.
+  ``4c49d99d560``
+
+  Under rare circumstances, the RRSet that expired at the time of the
+  query could be returned with TTL far in the future.  This has been
+  fixed.
+
+  As a side-effect, the expiration time of expired RRSets are no longer
+  printed out in the cache dump. :gl:`#5094` :gl:`!10060`
+
+- Yaml string not terminated in negative response in delv.
+  ``132947c0bad``
+
+  :gl:`#5098` :gl:`!9980`
+
+- Apply the memory limit only to ADB database items. ``7c90bd5bb3d``
+
+  Resolver under heavy-load could exhaust the memory available for
+  storing the information in the Address Database (ADB) effectively
+  evicting already stored information in the ADB.  The memory used to
+  retrieve and provide information from the ADB is now not a subject of
+  the same memory limits that are applied for storing the information in
+  the Address Database. :gl:`#5127` :gl:`!9976`
+
+- Avoid unnecessary locking in the zone/cache database. ``43c77d95f1d``
+
+  Prevent lock contention among many worker threads referring to the
+  same database node at the same time. This would improve zone and cache
+  database performance for the heavily contended database nodes.
+  :gl:`#5130` :gl:`!9965`
+
+- Fix the cache findzonecut() implementation. ``368315b3c7e``
+
+  The search for the deepest known zone cut in the cache could
+  improperly reject a node if it contained any stale data, regardless of
+  whether it was the NS RRset that was stale. :gl:`#5155` :gl:`!10051`
+
+- Improve the resolver performance under attack. ``2c667bc9c61``
+
+  A remote client can force the DNS resolver component to consume the
+  memory faster than cleaning up the resources for the canceled resolver
+  fetches due to `recursive-clients` limit. If the such traffic pattern
+  is sustained for a long period of time, the DNS server might
+  eventually run out of the available memory. This has been fixed.
+
+  It should be noted that when under such heavy attack for BIND 9
+  version both with and without the fix, no outgoing DNS queries will be
+  successful as the generated traffic pattern will consume all the
+  available slots for the recursive clients. :gl:`!9961`
