This release contains key tag signaling RFC8145 support.  B root is
renumbered in the default root hints.  The dnscrypt code supports the
chacha cipher.  The Unbound DNSSEC validator supports the ED25519
algorithm.  The redirect-bogus patch in contrib can send validation
failure users to a landing page.

- Implemented trust anchor signaling using key tag query.
- unbound-checkconf -o allows query of dnstap config variables.
  Also unbound-control get_option.  Also for dnscrypt.
- unbound.h exports the shm stats structures.  They use
  type long long and no ifdefs, and ub_ before the typenames.
- Implemented opportunistic IPsec support module (ipsecmod).
- Added redirect-bogus.patch to contrib directory.
- Support for the ED25519 algorithm with openssl (from openssl 1.1.1).
- renumbering B-Root's IPv6 address to 2001:500:200::b.
- Fix #1276: [dnscrypt] add XChaCha20-Poly1305 cipher.
- Fix #1277: disable domain ratelimit by setting value to 0.

Bug Fixes:
- Added ECS unit test (from Manu Bretelle).
- ECS documentation fix (from Manu Bretelle).
- Fix #1252: more indentation inconsistencies.
- Fix #1253: unused variable in edns-subnet/addrtree.c:getbit().
- Fix #1254: clarify ratelimit-{for,below}-domain (from Manu Bretelle).
- iana portlist update
- Based on #1257: check parse limit before t increment in sldns RR
  string parse routine.
- Fix #1258: Windows 10 X64 unbound 1.6.2 service will not start.
  and fix that 64bit getting installed in C:\Program Files (x86).
- Fix #1259: "--disable-ecdsa" argument overwritten
  by "#ifdef SHA256_DIGEST_LENGTH at daemon/remote.c".
- iana portlist update
- Added test for leak of stub information.
- Fix sldns wire2str printout of RR type CAA tags.
- Fix sldns int16_data parse.
- Fix sldns parse and printout of TSIG RRs.
- sldns SMIMEA and AVC definitions, same as getdns definitions.
- Fix tcp-mss failure printout text.
- Set SO_REUSEADDR on outgoing tcp connections to fix the bind before
  connect limited tcp connections.  With the option tcp connections
  can share the same source port (for different destinations).
- Add 'c' to getopt() in testbound.
- Adjust servfail by iterator to not store in cache when serve-expired
  is enabled, to avoid overwriting useful information there.
- Fix queries for nameservers under a stub leaking to the internet.
- document trust-anchor-signaling in example config file.
- updated configure, dependencies and flex output.
- better module memory lookup, fix of unbound-control shm names for
  module memory printout of statistics.
- Fix type AVC sldns rrdef.

- exec_prefix is by default equal to prefix.
- printout localzone for duplicate local-zone warnings.
- Fix assertion for low buffer size and big edns payload when worker
  overrides udpsize.
- Support for openssl EVP_DigestVerify.
- Fix #1269: inconsistent use of built-in local zones with views.
- Add defaults for new local-zone trees added to views using
- Fix #1273: cachedb.c doesn't compile with -Wextra.
- If MSG_FASTOPEN gives EPIPE fallthrough to try normal tcp write.
- Also use global local-zones when there is a matching view that does
  not have any local-zone specified.
- Fix fastopen EPIPE fallthrough to perform connect.
- Fix #1274: automatically trim chroot path from dnscrypt key/cert paths
  (from Manu Bretelle).
- Fix #1275: cached data in cachedb is never used.
- Fix that unbound-control can set val_clean_additional and

- Detect chacha for dnscrypt at configure time.
- dnscrypt unit tests with chacha.
- Added domain name based ECS whitelist.
- Fix #1278: Incomplete wildcard proof.
- Fix #1279: Memory leak on reload when python module is enabled.
- Fix #1280: Unbound fails assert when response from authoritative

- More fixes in depth for buffer checks in 0x20 qname checks.
- Fix stub zone queries leaking to the internet for
  harden-referral-path ns checks.

- Fix to unlock view in view test.
- Fix warning in pythonmod under clang compiler.
