Incompatible changes
--------------------
60 61 62 63 64 65 66
- 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

- 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

- 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

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
347
- also unknown ones?

Incompatible changes
--------------------
- lua: query flag-sets are no longer represented as plain integers.
357 358 359
  kres.query.* no longer works, and kr_query_t lost trivial methods

  You can instead write code like qry.flags.NO_0X20 = true.

Security
--------
- Fix a critical DNSSEC flaw.  Signatures might be accepted as valid

  sign it, assuming the trust chain to that DNSKEY was valid.

430 431 432 433 434 435 436 437 438
================================

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.

439 440
Improvements
------------
441 442
- major feature: support for forwarding with validation (#112).
  The old policy.FORWARD action now does that; the previous non-validating
443
  mode is still available as policy.STUB except that also uses caching (#122).
444
- command line: specify ports via @ but still support # for compatibility
445
- policy: recognize 100.64.0.0/10 as local addresses
446 447
- layer/iterate: *do* retry repeatedly if REFUSED, as we can't yet easily
  retry with other NSs while avoiding retrying with those who REFUSED
448 449
- modules: allow changing the directory where modules are found,
  and do not search the default library path anymore.
450

451 452 453

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 1.2.1 (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.

Knot Resolver 1.2.0 (2017-01-24)
596
====================================
597 598 599

Security:
---------
600 601
- 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.
602

603 604 605 606
Improvements:
-------------
- The DNSSEC Validation has been refactored, fixing many resolving
  failures.
607 608 609
- 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.
610 611
- hints module: previously /etc/hosts was loaded by default, but not anymore.
  Users can now actually avoid loading any file.
612 613 614
- 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
616 617 618 619 620 621

- Free TCP buffer on cancelled connection.
622
- Fix crash in hints module on empty hints file, and fix non-lowercase hints.
623

624 625
Miscellaneous:
--------------
626 627
- It now requires knot >= 2.3.1 to link successfully.
- The API+ABI for modules changed slightly.
628
- New LRU implementation.
