This has a number of new features. The dependency on libfstrm is removed. The fstrm protocol code resides in dnstap/dnstap_fstrm.h and dnstap/dnstap_fstrm.c. This contains a brief definition of what unbound needs. The make unbound-dnstap-socket builds a debug tool, unbound-dnstap-socket. It can listen, accept multiple DNSTAP streams and print information. Commandline options control it. Unbound can reconnect if the unix domain socket file socket is closed. This uses exponential backoff after which it uses a one second timer to throttle cpu down. There is also support to use TCP and TLS for connecting to the log server. There are new config options to turn them on, in the dnstap section in the man page and example config file. dnstap-ip with IP address of server for TCP or TLS use. dnstap-tls to turn on TLS. And dnstap-tls-server-name, dnstap-tls-cert-bundle, dnstap-tls-client-key-file and dnstap-tls-client-cert-file to configure the certificates for server authentication and client authentication, or leave at "" to not use that. 27 February 2020: George - Merge PR #171: Add additional compilers and platforms to Travis testing, by noloader. 27 February 2020: Wouter - Fix #169: Fix warning for daemon/remote.c output may be truncated from snprintf. - Fix #170: Fix gcc undefined sanitizer signed integer overflow warning in signature expiry RFC1982 serial number arithmetic. - Fix more undefined sanitizer issues, in respip copy_rrset null dname, and in the client_info_compare routine for null memcmp. 26 February 2020: Wouter - iana portlist updated. 25 February 2020: Wouter - Fix #165: Add prefer-ip4: yesno config option to prefer ipv4 for using ipv4 filters, because the hosts ip6 netblock /64 is not owned by one operator, and thus reputation is shared. 24 February 2020: George - Merge PR #166: Fix typo in unbound.service.in, by glitsj16. 20 February 2020: Wouter - Updated contrib/unbound_smf23.tar.gz with Solaris SMF service for Unbound from Yuri Voinov. - master branch has 1.10.1 version. 18 February 2020: Wouter - protect X509_CHECK_FLAG_NO_PARTIAL_WILDCARDS with ifdef for different openssl versions. 17 February 2020: Wouter - changelog point where the tag for 1.10.0rc2 release is.

The so-reuseport, harden-below-nxdomain, and minimal-responses options are enabled by default. They used to be disabled by default, waiting to make sure they worked. They are enabled by default now, and can be disabled explicitly by setting them to "no" in the unbound.conf config file. The reuseport and minimal options increases speed of the server, and should be otherwise harmless. The harden-below-nxdomain option works well together with the recently default enabled qname minimisation, this causes more fetches to use information from the cache. - next release is called 1.8.0. - Fix lintflags for lint on FreeBSD. 22 August 2018: George - #4140: Expose repinfo (comm_reply) to the inplace_callbacks.

That needs programs, that use it, to recompile against the new header definition. - print servfail info to log as error. - added more servfail printout statements, to the iterator. - log-servfail: yes prints log lines that say why queries are returning SERVFAIL to clients. 16 August 2018: Wouter - Fix warning on compile without threads. - Fix contrib/fastrpz.patch. 15 August 2018: Wouter - Fix segfault in auth-zone read and reorder of RRSIGs. 14 August 2018: Wouter - Fix that printout of error for cycle targets is a verbosity 4 printout and does not wrongly print it is a memory error. - Upgraded crosscompile script to include libunbound DLL in the zipfile. 10 August 2018: Wouter - Fix #4144: dns64 module caches wrong (negative) information. 9 August 2018: Wouter - unbound-checkconf checks if modules exist and prints if they are not compiled in the name of the wrong module. - document --enable-subnet in doc/README. - Patch for stub-no-cache and forward-no-cache options that disable caching for the contents of that stub or forward, for when you want immediate changes visible, from Bjoern A. Zeeb. 7 August 2018: Ralph - Make capsforid fallback QNAME minimisation aware. 7 August 2018: Wouter - Fix #4142: unbound.service.in: improvements and fixes. Add unit dependency ordering (based on systemd-resolved). Add 'CAP_SYS_RESOURCE' to 'CapabilityBoundingSet' (fixes warnings about missing privileges during startup).

And log the limit exceeded message only on high verbosity, so as to not spam the logs when it is busy. 6 August 2018: Wouter - Fix for #4136: Fix to unconditionally call destroy in daemon.c. 3 August 2018: George - Expose if a query (or a subquery) was ratelimited (not src IP ratelimiting) to libunbound under 'ub_result.was_ratelimited'. This also introduces a change to 'ub_event_callback_type' in libunbound/unbound-event.h. - Tidy pylib tests. 3 August 2018: Wouter - Revert previous change for #4136: because it introduces build problems. - New fix for #4136: This one ignores lex without without yylex_destroy. 1 August 2018: Wouter - Fix to remove systemd sockaddr function check, that is not always present. Make socket activation more lenient. But not different when socket activation is not used. - iana port list update. 31 July 2018: Wouter - Patches from Jim Hague (Sinodun) for EDNS KeepAlive. - Sort out test runs when the build directory isn't the project root directory. - Add config tcp-idle-timeout (default 30s). This applies to client connections only; the timeout on TCP connections upstream is unaffected. - Error if EDNS Keepalive received over UDP. - Add edns-tcp-keepalive and edns-tcp-keepalive timeout options and implement option in client responses. - Correct and expand manual page entries for keepalive and idle timeout. - Implement progressive backoff of TCP idle/keepalive timeout. - Fix 'make depend' to work when build dir is not project root. - Add delay parameter to streamtcp, -d secs.

Likewise, in order to know which ES version should be used. On the other hand, when rotating a cert, it can be desirable to only serve the new cert but still be able to handle clients that are still using the old certs's public key.
