Date: 15 Dec, 2016
Features
Added generic EDNS code for registering known EDNS option codes, bypassing the cache response stage and uniquifying mesh states. Four EDNS option lists were added to module_qstate (module_qstate.edns_opts_*) to store EDNS options from/to front/back side.
Added two flags to module_qstate (no_cache_lookup, no_cache_store) that control the modules' cache interactions.
Added code for registering inplace callback functions. The registered functions can be called just before replying with local data or Chaos, replying from cache, replying with SERVFAIL, replying with a resolved query, sending a query to a nameserver. The functions can inspect the available data and maybe change response/query related data (i.e. append EDNS options).
Updated Python module for the above.
Updated Python documentation.
Added views functionality.
Added qname-minimisation-strict config option.
Patch that resolves CNAMEs entered in local-data conf statements that point to data on the internet, from Jinmei Tatuya (Infoblox).
serve-expired config option: serve expired responses with TTL 0.
.gitattributes line for githubs code language display.
log-identity: config option to set sys log identity, patch from "Robin H. Johnson" (robbat2@gentoo.org).
Added stub-ssl-upstream and forward-ssl-upstream options.
Added local-zones and local-data bulk addition and removal functionality in unbound-control (local_zones, local_zones_remove, local_datas and local_datas_remove).
Bug Fixes
Fix #836: unbound could echo back EDNS options in an error response.
Fix #838: 1.5.10 cannot be built on Solaris, undefined PATH_MAX.
Fix #839: Memory grows unexpectedly with large RPZ files.
Fix #840: infinite loop in unbound_munin_ plugin on unowned lockfile.
Fix #841: big local-zone's make it consume large amounts of memory.

Fix Nits for 1.5.10 reported by Dag-Erling Smorgrav.

Patch for server.num.zero_ttl stats for count of expired replies, from Pavel Odintsov.
Fix failure to build on arm64 with no sbrk.
Set OpenSSL security level to 0 when using aNULL ciphers.
configure detects ssl security level API function in the autoconf manner. Every function on its own, so that other libraries (eg. LibreSSL) can develop their API without hindrance.
Fix #1154: segfault when reading config with duplicate zones.
Note that for harden-below-nxdomain the nxdomain must be secure, this means nsec3 with optout is insufficient.
Fix #1155: test status code of unbound-control in 04-checkconf, not the status code from the tee command.
Fix #1158: reference RFC 8020 "NXDOMAIN: There Really Is Nothing Underneath" for the harden-below-nxdomain option.
patch from Dag-Erling Smorgrav that removes code that relies on sbrk().
Make access-control-tag-data RDATA absolute. This makes the RDATA origin consistent between local-data and access-control-tag-data.
Fix NSEC ENT wildcard check. Matching wildcard does not have to be a subdomain of the NSEC owner.
QNAME minimisation uses QTYPE=A, therefore always check cache for this type in harden-below-nxdomain functionality.
Added unit test for QNAME minimisation + harden below nxdomain synergy.
Fix that with openssl 1.1 control-use-cert: no uses less cpu, by using no encryption over the unix socket.
