Other updates and bugfixes:

* Version 1.25.2:
* Features:
* TTL behavior changes: cached records reaching TTL 0 are expired; TTL 0
upstream answers are no longer cached by cachedb; serve-expired-reply-ttl is now capped by the original TTL value; TTL decoding updated to adhere to RFC 8767 section 4
* Add new statistics: num.queries.replyaddr_limit and
requestlist.current.replies
* Add 'log-thread-id' configuration option to log the system-wide
Linux thread ID for easier debugging
* Add ECC-GOST12 support per RFC 9558 (available as contrib/gost12.patch)
* Allow synthesized DNAME TTL=0 to be served from cache within a 1-second
grace period, reducing recursion for TTL=0 DNAMEs (RFC 2308)
* Fix DoT/DoH/DoQ to reload certificates on config reload without requiring
a full restart; fast_reload now supports changes to tls-service-key, tls-service-pem and tls-cert-bundle
* Allow ip@port notation in control-interface configuration
* Add iter-scrub-rrsig option (default: 8) to limit the number of RRSIGs
processed by the scrubber
* Add 'tls-protocols' configuration option to select which TLS
protocol versions are used; TLSv1.2 is re-enabled by default
* Add pthread_setname_np support for named threads
* Bug Fixes:
* Fix handle leak in pythonmod on pythonmod_init
* Fix crash when mesh_detect_cycle_found() is called with no mesh state
* Fix modstack_call_init to use the original string when it has changed
* Fix fr_atomic_copy_cfg

DNS64

interface-automatic-ports
* Allow wait-limit-cookie: 0 to disable cookie-validated wait limits

stub/forward zones

point when adding target addresses

* Fix DNS rebinding bypass via SVCB/HTTPS records; private-address now also
elides SVCB and HTTPS records matching the filter
* Warn for unused 'nodefault' local-zone configuration in
unbound-checkconf
* Fix lock/unlock for view in memory error handling
* Apply cache TTL policy to DNAME and synthesized CNAME on the wire path
* Fix detection of HTTP listening port in fast_reload
* Fix ignoring out-of-zone DNAME records for CNAME synthesis
* Fix invalid HTTP content length/chunk size checks and RR rdata field
length validation in zone transfer, preventing heap buffer-overflow read errors
* Fix defense in depth for service callback with empty packet
* Fix shared memory statistics with threads
* Fix EDNS client subnet to not store SERVFAIL in the global cache after a
failed lookup; stores a short-lived failure entry in the subnet cache instead
* Fix memory corruption related core dumps when alloc_reg_obtain encounters
an empty list
* Fix RFC 7766 compliance when client sends EOF over TCP
* Fix DoH session cleanup when the same query appears on multiple streams
* Fix TLS context setup for tls-service-pem
* Fix TTL comparisons in rdata_copy for 32-bit signed/unsigned values
* Fix memory leak in subnet SERVFAIL store
* Fix for the Jiggle Attack: server now answers errors for error cases and
no longer reflects parts of the incoming query
* Fix EDNS extended RCODE reflection: server no longer echoes extended
RCODE values after CHAOS class queries
* Fix iterator RCODE handling of YXDOMAIN: only accept YXDOMAIN answers
that contain a DNAME record
* Fix missing bounds check when decompressing dnames for downloaded
authority zones, preventing malformed content from truncated AXFR packets
* Fix upstream TLS connections being reused for different names at the same
IP address
* Fix to disallow signatures with revoked DNSKEYs
* Fix DNAME with unsigned CNAME to check for the correct match, preventing
certain zone configurations from granting secure status to unchecked CNAMEs
* Fix wildcard CNAME handling in the chain of trust
* Fix buffer overrun in doq_repinfo_retrieve_localaddr()
* Packaging changes:
* Update keyring to new NLnet Labs release signing key

<li>TTL behavior changes: cached records reaching TTL 0 are expired;
TTL 0 upstream answers are no longer cached by cachedb;
serve-expired-reply-ttl is now capped by the original TTL value;
TTL decoding updated to adhere to RFC 8767 section 4</li>
