Runs ok on dev server. Seems memory leaks fixed - memory consumption 
looks stable.

>
> It is possible to configure the persistent TCP connection, with the
> options max-reuse-tcp-queries and tcp-reuse-timeout. These also apply to
> TLS reused connections.
>
> The local zone types always_null, always_nodata and always_deny work

>
> The log servfail error message now includes more information, it
> attempts to add an IP address and information about the one of the last
> failures that is associated with that query.
>
> With the option tcp-auth-query-timeout, the time to wait for queries
> to upstream authority servers can be configured, for TCP and TLS queries.

> It is possible to configure unbound with --with-deprecate-rsa-1024, that
> stops the use of RSA 1024 keys. That makes unbound work with certain
> FIPS installations that do not allow such calls to the crypto API. If
> the option is enabled, Unbound treats RSA keys with an insufficiently
> sized key as not supported. Responses with unsupported crypto are marked
> insecure.
>
> The NSEC3 maximum iterations are lowered to 150. This is the new default
> setting. This puts this in line with other DNS implementations. If the
> iterations count is exceeded the response becomes insecure.
>
> The number of validator retries when there is a DNSSEC failure can be
> configured with the val-max-restart option.
>
> The RR types SVCB and HTTPS are supported according to the draft
> specification. The syntax can be used in local zones and zone files,
> and debug output. The types themselves were already supported on the
> wire the RFC3597 unknown RR type support.

> Features
> - Merge PR #317: ZONEMD Zone Verification, with RFC 8976 support.
>    ZONEMD records are checked for zones loaded as auth-zone,
>    with DNSSEC if available.  There is an added option
>    zonemd-permissive-mode that makes it log but not fail wrong zones.
>    With zonemd-reject-absence for an auth-zone the presence of a
>    zonemd can be mandated for specific zones.
> - Fix: Resolve interface names on control-interface too.
> - Merge #470 from edevil: Allow configuration of persistent TCP
>    connections.
> - Fix #474: always_null and others inside view.
> - Add that log-servfail prints an IP address and more information
>    about one of the last failures for that query.
> - Merge #478: Allow configuration of TCP timeout while waiting for
>    response.
> - Add ./configure --with-deprecate-rsa-1024 that turns off RSA 1024.
> - Move the NSEC3 max iterations count in line with the 150 value
>    used by BIND, Knot and PowerDNS. This sets the default value
>    for it in the configuration to 150 for all key sizes.
> - zonemd-check: yesno option, default no, enables the processing
>    of ZONEMD records for that zone.
> - Merge #486 by fobster: Make VAL_MAX_RESTART_COUNT configurable.
> - Merge PR #491: Add SVCB and HTTPS types and handling according to
>    draft-ietf-dnsop-svcb-https.
> - Introduce 'http-user-agent:' and 'hide-http-user-agent:' options.
>
> Bug Fixes
> - Fix for Python 3.9, no longer use deprecated functions of
>    PyEval_CallObject (now PyObject_Call), PyEval_InitThreads (now
>    none), PyParser_SimpleParseFile (now Py_CompileString).
> - Merge PR #420 from dyunwei: DOH not responsing with
>    "http2_query_read_done failure" logged.

>    and udp connect from the logs, unless at high verbosity.
> - Fix for zonemd, that nxdomain for the chain of trust is allowed
>    for island zones, it is treated as an insecure zone for verification.
> - Fix for zonemd, that domain-insecure zones work without dnssec.
> - Fix for zonemd, do not reject insecure result from trust anchor
>    validation step in dnssec chain of trust.
> - On startup of unbound it checks if rlimits on memory size look
>    sufficient for the configured cache size, and logs warning if not.
> - Fix function documentation.
> - Fix unit test for added ulimit checks.
> - spelling fix in header.
> - Fix #384: (1) A minor request to improve the log (2) A minor bug in one
>    log message.
> - ipsecmod: Better logging for detecting a cycle when attaching the

>    FORWARDER_QUERY.
> - Fix to allow rpz with wildcard that applies to all TLDs at once.
> - Fix for #367: rc_ports don't have ub_sock; skip cleaning up.
