Description :
Knot DNS is a high-performance authoritative DNS server implementation.

Update Information:

Major updates for Knot DNS and Knot Resolver: 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 1.4.0 (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 DNS 2.6.1
(2017-11-02) ===========================  Features: ---------  - NSEC3 Opt-Out
support in the DNSSEC signing  - New CDS/CDNSKEY publish configuration option
Improvements: -------------  - Simplified DNSSEC log message with DNSKEY details
- +tls-hostname in kdig implies +tls-ca if neither +tls-ca nor +tls-pin is given
- New documentation sections for DNSSEC key rollovers and shared keys  - Keymgr
no longer prints useless algorithm number for generated key  - Kdig prints
unknown RCODE in a numeric format  - Better support for LLVM libFuzzer
Bugfixes: ---------  - Faulty DNAME semantic check if present in the zone apex
and NSEC3 is used  - Immediate zone flush not scheduled during the zone load
event  - Server crashes upon dynamic zone addition if a query module is loaded
- Kdig fails to connect over TLS due to SNI is set to server IP address  -
Possible out-of-bounds memory access at the end of the input  - TCP Fast Open
enabled by default in kdig breaks TLS connection  Knot DNS 2.6.0 (2017-09-29)
===========================  Features: ---------  - On-slave (inline) signing
support  - Automatic DNSSEC key algorithm rollover  - Ed25519 algorithm support
in DNSSEC (requires GnuTLS 3.6.0)  - New 'journal-content' and 'zonefile-load'
configuration options  - keymgr tries to run as user/group set in the
configuration  - Public-only DNSSEC key import into KASP DB via keymgr  - NSEC3
resalt and parent DS query events are persistent in timer DB  - New processing
state for a response suppression within a query module  - Enabled server side
TCP Fast Open if supported  - TCP Fast Open support in kdig  Improvements:
-------------  - Better record owner compression if related to the previous
rdata dname  - NSEC(3) chain is no longer recomputed whole on every update  -
Remove inconsistent and unnecessary quoting in log files  - Avoiding of
overlapping key rollovers at a time  - More DNSSSEC-related semantic checks  -
Extended timestamp format in keymgr  Bugfixes: ---------  - Incorrect journal
free space computation causing inefficient space handling  - Interface-automatic
broken on Linux in the presence of asymmetric routing  Knot DNS 2.5.6
(2017-11-02) ===========================  Improvements: -------------  - Keymgr
no longer prints useless algorithm number for generated key  Bugfixes: ---------
- Faulty DNAME semantic check if present in the zone apex and NSEC3 is used  -
Immediate zone flush not scheduled during the zone load event  - Server crashes
upon dynamic zone addition if a query module is loaded  - Kdig fails to connect
over TLS due to SNI is set to server IP address  Knot DNS 2.5.5 (2017-09-29)
===========================  Improvements: -------------  - Constant time memory
comparison in the TSIG processing  - Proper use of the ctype functions  -
Generated RRSIG records have inception time 90 minutes in the past  Bugfixes:
---------  - Incorrect online signature for NSEC in the case of a CNAME record
- Incorrect timestamps in dnstap records  - EDNS Subnet Client validation
rejects valid payloads  - Module configuration semantic checks are not executed
- Kzonecheck segfaults with unusual inputs  Knot DNS 2.5.4 (2017-08-31)
===========================  Improvements: -------------  - New minimum and
maximum refresh interval config options (Thanks to Manabu Sonoda)  - New warning
when unforced flush with disabled zone file synchronization  - New 'dnskey'
keymgr command  - Linking with libatomic on architectures that require it
(Thanks to Pierre-Olivier Mercier)  - Removed 'OK' from listing keymgr command
outputs  - Extended journal and keymgr documentation and logging  Bugfixes:
---------  - Incorrect handling of specific corner-cases with zone-in-journal  -
The 'share' keymgr command doesn't work  - Server crashes if configured with
query-size and reply-size statistics options  - Malformed big integer
configuration values on some 32-bit platforms  - Keymgr uses local time when
parsing date inputs  - Memory leak in kdig upon IXFR query
