+ Fix handling of 5014 (INVALID_AVP_LENGTH) errors.</p>
+ <p>
+ This was in some cases reported as 3009
+ (INVALID_AVP_BITS).</p>
+ <p>
+ Note that the correction is partially implemented in
+ modules generated by diameterc(1): a dictionary file must
+ be recompiled for the correction to apply to any messages

+ <p>
+ Fix watchdog memory leak.</p>
+ <p>
+ Entries were not removed from a service-specific ets
+ table, causing them to be orphaned at connection
+ reestablishment for listening transports, and
+ diameter:remove_transport/2 for both listening and
+ connecting transports.</p>
+ <p>
+ The fault was introduced by OTP-10692 in diameter-1.4.1
+ (R16B).</p>

+ Fix decode failure on AVP Length &lt; 8.</p>
+ <p>
+ The failure caused the message in question to be

+ <item>
+ <p>
+ Respect Host-IP-Address configuration.</p>
+ <p>
+ Addresses returned from a transport module were always
+ used to populate Host-IP-Address AVP's in an outgoing
+ CER/CEA, which precluded the sending of a VIP address.
+ Transport addresses are now only used if Host-IP-Address
+ is unspecified.</p>

+ <p>
+ Install could fail if examples/code and examples/dict
+ were created in parallel. Noticed on FreeBSD.</p>

+ </item>
+ <item>
+ <p>
+ Fix recognition of 5001 on mandatory AVP's.</p>
+ <p>
+ An AVP setting the M-bit was not regarded as erroneous if
+ it was defined in the dictionary in question and its
+ container (message or Grouped AVP) had an 'AVP' field.
+ It's now regarded as a 5001 error (AVP_UNSUPPORTED), as
+ in the case that the AVP is not defined.</p>
+ <p>
+ Note that the correction is partially implemented in
+ modules generated by diameterc(1): a dictionary file must
+ be recompiled for the correction to apply to any messages
+ it defines.</p>

+ <item>
+ <p>
+ Fix setting of Failed-AVP on handle_request
+ {answer_message, 5xxx} return.</p>
+ <p>
+ Failed-AVP was never in the outgoing answer-message. It
+ is now set with the AVP from the first entry with the
+ specified Result-Code in the errors field of the incoming
+ diameter_packet, if found.</p>

+ <p>
+ Fix watchdog function_clause</p>
+ <p>
+ A listening transport on a service that allowed multiple
+ connections to the same peer could result in a
+ function_clause error in module diameter_watchdog. The
+ resulting crash was harmless but unseemly.</p>
+ <p>
+ Thanks to Aleksander Nycz.</p>

+ Own Id: OTP-11115</p>
+ </item>
+ <item>
+ <p>
+ Fix population of Failed-AVP.</p>
+ <p>
+ In cases in which diameter populated this AVP, many
+ values were sent instead of one as suggested by RFC 6733.
+ This was partially corrected by OTP-11007.</p>

+ </item>
+ <item>
+ <p>
+ Fix list-valued Vendor-Specific-Application-Id config</p>
+ <p>
+ R16B (specifically, OTP-10760) broke the handling of such
+ configuration, resulting in a function clause error if
+ the list was not of length 3, and faulty interpretation
+ of the list's contents otherwise. Only record-valued
+ configuration was properly interpreted.</p>

+ <item>
+ <p>
+ Allow peer connections to be shared between Erlang nodes
+ for the purpose of sending outgoing requests.</p>
+ <p>
+ A diameter_app(3) pick_peer/4 callback gets a list of
+ remote candidates as argument, allowing a callback on one
+ node to select a transport connection established on
+ another node. The service_opt() share_peers controls the
+ extent to which local connections are shared with remote
+ nodes. The service_opt() use_shared_peers controls the
+ extent to which connections shared from remote nodes are
+ utilized on the local node.</p>
+ <p>
+ Own Id: OTP-9610</p>
+ </item>
+ <item>
+ <p>
+ Allow listening diameter_{tcp,sctp} transports to be
+ configured with remote addresses.</p>
+ <p>
+ Option 'accept' allows remote addresses to be configured
+ as tuples or regular expressions. Remote addresses are
+ matched against the configured values at connection
+ establishment, any non-matching address causing the
+ connection to be aborted.</p>
+ <p>
+ Own Id: OTP-10893</p>
+ </item>
+ <item>
+ <p>
+ Detect more transport_opt() configuration errors at
+ diameter:add_transport/2.</p>
+ <p>
+ Many errors would previously not be detected until
+ transport start, diameter:add_transport/2 returning 'ok'
+ but transport connections failing to be established. An
+ error tuple is now returned.</p>
+ <p>
+ Own Id: OTP-10972</p>
+ </item>
+ <item>
+ <p>
+ Make explicit local address configuration optional in
+ diameter_tcp:start/3.</p>
+ <p>
+ The default address (as determined by gen_tcp) is now
+ used when a local address is not explicitly configured.</p>
+ <p>
+ Own Id: OTP-10986</p>
+ </item>
+ <item>
+ <p>
+ Improve handling of unrecognized service options.</p>
+ <p>
+ Such options were silently ignored by
+ diameter:start_service/2. An error tuple is now returned.</p>
+ <p>
+ Own Id: OTP-11017</p>
+ </item>
+ <item>
+ <p>
+ Don't send default Inband-Security-Id in CER/CEA.</p>
+ <p>
+ RFC 6733 recommends against the use of
+ Inband-Security-Id. Only send a value that differs from
+ the default, NO_INBAND_SECURITY = 0.</p>
+ <p>
+ Own Id: OTP-11050</p>
+ </item>

+ <p>
+ Make spawn options for request processes configurable.</p>
