  (!711, credit Manu Bretelle)
- net.bpf bindings allow advanced users to use eBPF socket filters

Bugfixes
--------
- http module: only run prometheus in parent process if using --forks=N,
  as the submodule collects metrics from all sub-processes as well.
- TLS fixes for corner cases (!700, !714, !716, !721, !728)

- policy.{FORWARD,TLS_FORWARD,STUB}: give advantage to IPv6
  when choosing whom to ask, just as for iteration
- use pseudo-randomness from gnutls instead of internal ISAAC (#233)
- tune the way we deal with non-responsive servers (!716, !723)
- documentation clarifies interaction between policy and view modules (!678, !730)

Knot Resolver 3.0.0 (2018-08-20)
================================

Incompatible changes
--------------------
- cache: fail lua operations if cache isn't open yet (!639)
  By default cache is opened *after* reading the configuration,
  and older versions were silently ignoring cache operations.
  Valid configuration must open cache using `cache.open()` or `cache.size =`
  before executing cache operations like `cache.clear()`.
- libknot >= 2.7.1 is required, which brings also larger API changes
- in case you wrote custom Lua modules, please consult
  https://knot-resolver.readthedocs.io/en/latest/lib.html#incompatible-changes-since-3-0-0
- in case you wrote custom C modules, please see compile against
  Knot DNS 2.7 and adjust your module according to messages from C compiler
- DNS cookie module (RFC 7873) is not available in this release,
  it will be later reworked to reflect development in IEFT dnsop working group
- version module was permanently removed because it was not really used by users;
  if you want to receive notifications abou new releases please subscribe to
  https://lists.nic.cz/cgi-bin/mailman/listinfo/knot-resolver-announce

Bugfixes
--------
- fix multi-process race condition in trust anchor maintenance (!643)

  and will change in further versions but we need to gather operational
  experience first.)

Bugfixes
--------
- don't magically -D_FORTIFY_SOURCE=2 in some cases
- allow large responses for outbound over TCP
- fix crash with RR sets with over 255 records


Knot Resolver 2.1.1 (2018-02-23)

--------
- when iterating, avoid unnecessary queries for NS in insecure parent.
  This problem worsened in 2.0.0. (#246)
- prevent UDP packet leaks when using TLS forwarding
- fix the hints module also on some other systems, e.g. Gentoo.


Knot Resolver 2.1.0 (2018-02-16)

- stats: remove tracking of expiring records (predict uses another way)
- systemd: re-use a single kresd.socket and kresd-tls.socket

Knot Resolver 2.0.0 (2018-01-31)
================================

Incompatible changes
--------------------
- systemd: change unit files to allow running multiple instances,
  deployments with single instance now must use `kresd@1.service`
  instead of `kresd.service`; see kresd.systemd(7) for details
- systemd: the directory for cache is now /var/cache/knot-resolver
- unify default directory and user to `knot-resolver`
- directory with trust anchor file specified by -k option must be writeable
- policy module is now loaded by default to enforce RFC 6761;
  see documentation for policy.PASS if you use locally-served DNS zones
- drop support for alternative cache backends memcached, redis,
  and for Lua bindings for some specific cache operations
- REORDER_RR option is not implemented (temporarily)

New features
------------
- aggressive caching of validated records (RFC 8198) for NSEC zones;
  thanks to ICANN for sponsoring this work.
- forwarding over TLS, authenticated by SPKI pin or certificate.
  policy.TLS_FORWARD pipelines queries out-of-order over shared TLS connection
  Beware: Some resolvers do not support out-of-order query processing.
  TLS forwarding to such resolvers will lead to slower resolution or failures.
- trust anchors: you may specify a read-only file via -K or --keyfile-ro
- trust anchors: at build-time you may set KEYFILE_DEFAULT (read-only)
- ta_sentinel module implements draft ietf-dnsop-kskroll-sentinel-00,
  enabled by default
- serve_stale module is prototype, subject to change
- extended API for Lua modules

Bugfixes
--------
- fix build on osx - regressed in 1.5.3 (different linker option name)


Knot Resolver 1.5.3 (2018-01-23)
================================

Bugfixes
--------
- fix the hints module on some systems, e.g. Fedora.
  Symptom: `undefined symbol: engine_hint_root_file`


Knot Resolver 1.5.2 (2018-01-22)
================================

Security
--------
- fix CVE-2018-1000002: insufficient DNSSEC validation, allowing
  attackers to deny existence of some data by forging packets.
  Some combinations pointed out in RFC 6840 sections 4.1 and 4.3
  were not taken into account.

Bugfixes
--------
- memcached: fix fallout from module rename in 1.5.1


Knot Resolver 1.5.1 (2017-12-12)
================================

Incompatible changes
--------------------
- script supervisor.py was removed, please migrate to a real process manager
- module ketcd was renamed to etcd for consistency
- module kmemcached was renamed to memcached for consistency

Bugfixes
--------
- fix SIGPIPE crashes (#271)
- tests: work around out-of-space for platforms with larger memory pages
- lua: fix mistakes in bindings affecting 1.4.0 and 1.5.0 (and 1.99.1-alpha),
  potentially causing problems in dns64 and workarounds modules
- predict module: various fixes (!399)

Improvements
------------
- add priming module to implement RFC 8109, enabled by default (#220)
- add modules helping with system time problems, enabled by default;
  for details see documentation of detect_time_skew and detect_time_jump


Knot Resolver 1.5.0 (2017-11-02)
================================

Bugfixes
--------
- fix loading modules on Darwin

Improvements
------------
- new module ta_signal_query supporting Signaling Trust Anchor Knowledge
  using Keytag Query (RFC 8145 section 5); it is enabled by default
- attempt validation for more records but require it for fewer of them
  (e.g. avoids SERVFAIL when server adds extra records but omits RRSIGs)


Knot Resolver 1.99.1-alpha (2017-10-26)
=======================================
This is an experimental release meant for testing aggressive caching.
It contains some regressions and might (theoretically) be even vulnerable.
The current focus is to minimize queries into the root zone.

Improvements
------------
- negative answers from validated NSEC (NXDOMAIN, NODATA)
- verbose log is very chatty around cache operations (maybe too much)

Regressions
-----------
- dropped support for alternative cache backends
  and for some specific cache operations
- caching doesn't yet work for various cases:
    * negative answers without NSEC (i.e. with NSEC3 or insecure)
	* +cd queries (needs other internal changes)
	* positive wildcard answers
- spurious SERVFAIL on specific combinations of cached records, printing:
	<= bad keys, broken trust chain
- make check
- a few Deckard tests are broken, probably due to some problems above
- also unknown ones?



Knot Resolver 1.4.0 (2017-09-22)
================================

Incompatible changes
--------------------
- lua: query flag-sets are no longer represented as plain integers.
  kres.query.* no longer works, and kr_query_t lost trivial methods
  'hasflag' and 'resolved'.
  You can instead write code like qry.flags.NO_0X20 = true.

Bugfixes
--------
- fix exiting one of multiple forks (#150)
- cache: change the way of using LMDB transactions.  That in particular
  fixes some cases of using too much space with multiple kresd forks (#240).

Improvements
------------
- policy.suffix: update the aho-corasick code (#200)
- root hints are now loaded from a zonefile; exposed as hints.root_file().
  You can override the path by defining ROOTHINTS during compilation.
- policy.FORWARD: work around resolvers adding unsigned NS records (#248)
- reduce unneeded records previously put into authority in wildcarded answers


Knot Resolver 1.3.3 (2017-08-09)
================================

Security
--------
- Fix a critical DNSSEC flaw.  Signatures might be accepted as valid
  even if the signed data was not in bailiwick of the DNSKEY used to
  sign it, assuming the trust chain to that DNSKEY was valid.

Bugfixes
--------
- iterate: skip RRSIGs with bad label count instead of immediate SERVFAIL
- utils: fix possible incorrect seeding of the random generator
- modules/http: fix compatibility with the Prometheus text format

Improvements
------------
- policy: implement remaining special-use domain names from RFC6761 (#205),
  and make these rules apply only if no other non-chain rule applies


Knot Resolver 1.3.2 (2017-07-28)
================================

Security
--------
- fix possible opportunities to use insecure data from cache as keys
  for validation

Bugfixes
--------
- daemon: check existence of config file even if rundir isn't specified
- policy.FORWARD and STUB: use RTT tracking to choose servers (#125, #208)
- dns64: fix CNAME problems (#203)  It still won't work with policy.STUB.
- hints: better interpretation of hosts-like files (#204)
         also, error out if a bad entry is encountered in the file
- dnssec: handle unknown DNSKEY/DS algorithms (#210)
- predict: fix the module, broken since 1.2.0 (#154)

Improvements
------------
- embedded LMDB fallback: update 0.9.18 -> 0.9.21


Knot Resolver 1.3.1 (2017-06-23)
================================

Bugfixes
--------
- modules/http: fix finding the static files (bug from 1.3.0)
- policy.FORWARD: fix some cases of CNAMEs obstructing search for zone cuts


Knot Resolver 1.3.0 (2017-06-13)
================================

Security
--------
- Refactor handling of AD flag and security status of resource records.
  In some cases it was possible for secure domains to get cached as
  insecure, even for a TLD, leading to disabled validation.
  It also fixes answering with non-authoritative data about nameservers.

Improvements
------------
- major feature: support for forwarding with validation (#112).
  The old policy.FORWARD action now does that; the previous non-validating
  mode is still available as policy.STUB except that also uses caching (#122).
- command line: specify ports via @ but still support # for compatibility
- policy: recognize 100.64.0.0/10 as local addresses
- layer/iterate: *do* retry repeatedly if REFUSED, as we can't yet easily
  retry with other NSs while avoiding retrying with those who REFUSED
- modules: allow changing the directory where modules are found,
  and do not search the default library path anymore.

Bugfixes
--------
- validate: fix insufficient caching for some cases (relatively rare)
- avoid putting "duplicate" record-sets into the answer (#198)


Knot Resolver 1.2.6 (2017-04-24)
================================

Security
--------
- dnssec: don't set AD flag for NODATA answers if wildcard non-existence
  is not guaranteed due to opt-out in NSEC3

Improvements
------------
- layer/iterate: don't retry repeatedly if REFUSED

Bugfixes
--------
- lib/nsrep: revert some changes to NS reputation tracking that caused
  severe problems to some users of 1.2.5 (#178 and #179)
- dnssec: fix verification of wildcarded non-singleton RRsets
- dnssec: allow wildcards located directly under the root
- layer/rrcache: avoid putting answer records into queries in some cases


Knot Resolver 1.2.5 (2017-04-05)
================================

Security
--------
- layer/validate: clear AD if closest encloser proof has opt-outed
  NSEC3 (#169)
- layer/validate: check if NSEC3 records in wildcard expansion proof
  has an opt-out
- dnssec/nsec: missed wildcard no-data answers validation has been
  implemented

Improvements
------------
- modules/dnstap: a DNSTAP support module
  (Contributed by Vicky Shrestha)
- modules/workarounds: a module adding workarounds for known
  DNS protocol violators
- layer/iterate: fix logging of glue addresses
- kr_bitcmp: allow bits=0 and consequently 0.0.0.0/0 matches in view
  and renumber modules.
- modules/padding: Improve default padding of responses
  (Contributed by Daniel Kahn Gillmor)
- New kresc client utility (experimental; don't rely on the API yet)

Bugfixes
--------
- trust anchors: Improve trust anchors storage format (#167)
- trust anchors: support non-root TAs, one domain per file
- policy.DENY: set AA flag and clear AD flag
- lib/resolve: avoid unnecessary DS queries
- lib/nsrep: don't treat servers with NOIP4 + NOIP6 flags as timeouted
- layer/iterate: During packet classification (answer vs. referral)
  don't analyze AUTHORITY section in authoritative answer if ANSWER
  section contains records that have been requested


Knot Resolver 1.2.4 (2017-03-09)
================================

Security
--------
- Knot Resolver 1.2.0 and higher could return AD flag for insecure
  answer if the daemon received answer with invalid RRSIG several
  times in a row.

Improvements
------------
- modules/policy: allow QTRACE policy to be chained with other
  policies
- hints.add_hosts(path): a new property
- module: document the API and simplify the code
- policy.MIRROR: support IPv6 link-local addresses
- policy.FORWARD: support IPv6 link-local addresses
- add net.outgoing_{v4,v6} to allow specifying address to use for
  connections

Bugfixes
--------
- layer/iterate: some improvements in cname chain unrolling
- layer/validate: fix duplicate records in AUTHORITY section in case
  of WC expansion proof
- lua: do *not* truncate cache size to unsigned
- forwarding mode: correctly forward +cd flag
- fix a potential memory leak
- don't treat answers that contain DS non-existance proof as insecure
- don't store NSEC3 and their signatures in the cache
- layer/iterate: when processing delegations, check if qname is at or
  below new authority


Knot Resolver 1.2.3 (2017-02-23)
================================

Bugfixes
--------
- Disable storing GLUE records into the cache even in the
  (non-default) QUERY_PERMISSIVE mode
- iterate: skip answer RRs that don't match the query

---------
- Fix -k argument processing to avoid out-of-bounds memory accesses
- lib/resolve: fix zonecut fetching for explicit DS queries
- hints: more NULL checks
- Fix TA bootstrapping for multiple TAs in the IANA XML file

Testing:
--------
- Update tests to run tests with and without QNAME minimization


Knot Resolver 1.2.1 (2017-02-01)
====================================

Security:
---------
- Under certain conditions, a cached negative answer from a CD query
  would be reused to construct response for non-CD queries, resulting
  in Insecure status instead of Bogus.  Only 1.2.0 release was affected.

Documentation
-------------
- Update the typo in the documentation: The query trace policy is
  named policy.QTRACE (and not policy.TRACE)

Bugfixes:
---------
- lua: make the map command check its arguments


Knot Resolver 1.2.0 (2017-01-24)
====================================

Security:
---------
- In a policy.FORWARD() mode, the AD flag was being always set by mistake.
  It is now cleared, as the policy.FORWARD() doesn't do DNSSEC validation yet.

Improvements:
-------------
- The DNSSEC Validation has been refactored, fixing many resolving
  failures.
- Add module `version` that checks for updates and CVEs periodically.
- Support RFC7830: EDNS(0) padding in responses over TLS.
- Support CD flag on incoming requests.
- hints module: previously /etc/hosts was loaded by default, but not anymore.
  Users can now actually avoid loading any file.
- DNS over TLS now creates ephemeral certs.
- Configurable cache.{min,max}_tll option, with max_ttl defaulting to 6 days.
- Option to reorder RRs in the response.
- New policy.QTRACE policy to print packet contents

Bugfixes:
---------
- Trust Anchor configuration is now more robust.
- Correctly answer NOTIMPL for meta-types and non-IN RR classes.
- Free TCP buffer on cancelled connection.
- Fix crash in hints module on empty hints file, and fix non-lowercase hints.

Miscellaneous:
--------------
- It now requires knot >= 2.3.1 to link successfully.
- The API+ABI for modules changed slightly.
- New LRU implementation.
