- Added serve-stale functionality as described in
draft-ietf-dnsop-serve-stale-10. `serve-expired-*` options can be used
to configure the behavior.
- Updated cachedb to honor `serve-expired-ttl`; Fixes#107.
- Renamed statistic `num.zero_ttl` to `num.expired` as expired replies
come with a configurable TTL value (`serve-expired-reply-ttl`).
- Fixed stats when replying with cached, cname-aliased records.
- Added missing default values for redis cachedb backend.
This adds the possibility to properly register inplace callbacks in the
dynamic library module. It works by creating a wrapper procedure that
is available to the dynamic library and will call the given callback
through a whitelisted callback function.
The dynamic library example has already been improved to include
comments and some simple examples on allocating and deallocating memory
and registering callbacks.
add sockaddr_storage getters, add support for query callbacks,
allow raw address access via comm_reply and update API documentation.

- Limit ECS scope returned to client to the scope used for caching.
- Make lint like previous #4154 fix.

- (de)register inplace callbacks for module id
- No unbound-control set_option for ECS options
- Deprecated client-subnet-opcode config option
- Introduced client-subnet-always-forward config option
- Changed max-client-subnet-ipv6 default to 56 (as in RFC)
- Removed extern ECS config options
- module_restart_next now calls clear on all following modules
- Also create ECS module qstate on module_event_pass event

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.

after parse use edns_opt_find(edns.opt_list, LDNS_EDNS_NSID),
to insert use edns_opt_append(edns, region, code, len, bindata) on
the opt_list passed to send_query, or in edns_opt_inplace_reply.

For particular names you can configure exceptions in unbound.conf.
