+
+Security Fixes
+~~~~~~~~~~~~~~
+
+- [CVE-2024-12705] DNS-over-HTTP(s) flooding fixes. ``e733e624147``
+
+  Fix DNS-over-HTTP(S) implementation issues that arise under heavy
+  query load. Optimize resource usage for :iscman:`named` instances that
+  accept queries over DNS-over-HTTP(S).
+
+  Previously, :iscman:`named` would process all incoming HTTP/2 data at
+  once, which could overwhelm the server, especially when dealing with
+  clients that send requests but don't wait for responses. That has been
+  fixed. Now, :iscman:`named` handles HTTP/2 data in smaller chunks and
+  throttles reading until the remote side reads the response data. It
+  also throttles clients that send too many requests at once.
+
+  Additionally, :iscman:`named` now carefully processes data sent by
+  some clients, which can be considered "flooding." It logs these
+  clients and drops connections from them. :gl:`#4795`
+
+  In some cases, :iscman:`named` could leave DNS-over-HTTP(S)
+  connections in the `CLOSE_WAIT` state indefinitely. That also has been
+  fixed. ISC would like to thank JF Billaud for thoroughly investigating
+  the issue and verifying the fix. :gl:`#5083` :gl:`#4795` :gl:`#5083`
+
+- [CVE-2024-11187] Limit the additional processing for large RDATA sets.
+  ``c6e6a7af8ac``
+
+  When answering queries, don't add data to the additional section if
+  the answer has more than 13 names in the RDATA. This limits the number
+  of lookups into the database(s) during a single client query, reducing
+  query processing load. :gl:`#5034`
+
+New Features
+~~~~~~~~~~~~
+
+- Add a new option to configure the maximum number of outgoing queries
+  per client request. ``64b2b6edffa``
+
+  The configuration option 'max-query-count' sets how many outgoing
+  queries per client request is allowed. The existing
+  'max-recursion-queries' is the number of permissible queries for a
+  single name and is reset on every CNAME redirection. This new option
+  is a global limit on the client request. The default is 200.
+
+  This allows us to send a bit more queries while looking up a single
+  name. The default for 'max-recursion-queries' is changed from 32 to
+  50. :gl:`#4980`  :gl:`#4921` :gl:`!9847`
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- Update picohttpparser.{c,h} with upstream repository. ``326b445e469``
+
+  :gl:`#4485` :gl:`!9864`
+
+- Remove unused maxquerycount. ``c30067bb2f3``
+
+  Related to #4980 :gl:`!9854`
+
+- Use query counters in validator code. ``b1207ea9ed6``
+
+  Commit af7db8951364a89c468eda1535efb3f53adc2c1f as part of #4141 was
+  supposed to apply the 'max-recursion-queries' quota to validator
+  queries, but the counter was never actually passed on to
+  'dns_resolver_createfetch()'. This has been fixed, and the global
+  query counter ('max-query-count', per client request) is now also
+  added.
+
+  Related to #4980 :gl:`!9867`
+
+Bug Fixes
+~~~~~~~~~
+
+- Fix nsupdate hang when processing a large update. ``9a0588f7cf2``
+
+  To mitigate DNS flood attacks over a single TCP connection, we
+  throttle the connection when the other side does not read the data.
+  Throttling should only occur on server-side sockets, but erroneously
+  also happened for nsupdate, which acts as a client. When nsupdate
+  started throttling the connection, it never attempts to read again.
+  This has been fixed.   :gl:`#4910` :gl:`!9835`
+
+- Fix possible assertion failure when reloading server while processing
+  updates. ``1d4e60c9ba9``
+
+  :gl:`#5006` :gl:`!9821`
+
+- Fix dnssec-signzone signing non-DNSKEY RRsets with revoked keys.
+  ``bf2f4d4aad8``
+
+  `dnssec-signzone` was using revoked keys for signing RRsets other than
+  DNSKEY.  This has been corrected. :gl:`#5070` :gl:`!9841`
+
+- Unknown directive in resolv.conf not handled properly. ``75ae186fa1f``
+
+  The line after an unknown directive in resolv.conf could accidentally
+  be skipped, potentially affecting dig, host, nslookup, nsupdate, or
+  delv. This has been fixed. :gl:`#5084` :gl:`!9878`
+
+- Fix a bug in isc_rwlock_trylock() ``f68e60b3dc4``
+
+  When isc_rwlock_trylock() fails to get a read lock because another
+  writer was faster, it should wake up other waiting writers in case
+  there are no other readers, but the current code forgets about the
+  currently active writer when evaluating 'cntflag'.
+
+  Unset the WRITER_ACTIVE bit in 'cntflag' before checking to see if
+  there are other readers, otherwise the waiting writers, if they exist,
+  might not wake up. :gl:`#5121` :gl:`!9937`
