The version 18.3.4.3 is missing and seems to have had no
announcement or README, I do not know why.

+
+ --- Fixed Bugs and Malfunctions ---
+
+  OTP-14522    Application(s): compiler
+               Related Id(s): ERIERL-48
+
+               Fail labels on guard BIFs weren't taken into account
+               during an optimization pass, and a bug in the
+               validation pass sometimes prevented this from being
+               noticed when a fault occurred.
+
+
+  OTP-14526    Application(s): compiler
+
+               When compiling from Core Erlang, an 'apply' with a
+               nested apply in the function position would be treated
+               as an invalid call. Corrected. (Thanks to Mikael
+               Pettersson for reporting this bug.)
+
+
+  OTP-14591    Application(s): compiler
+
+               Fixed checking of binary matching in the beam_validator
+               module to ensure that potential compiler bugs are found
+               at compile-time instead as emulator crash at run-time.
+
+
+  OTP-14600    Application(s): compiler, stdlib
+               Related Id(s): ERL-478
+
+               There could be false warnings for
+               erlang:get_stacktrace/0 being used outside of a try
+               block when using multiple catch clauses.
+
+
+ --- Improvements and New Features ---
+
+  OTP-14378    Application(s): compiler, stdlib
+
+               The Erlang code linter no longer checks that the
+               functions mentioned in nowarn_deprecated_function
+               options are declared in the module.

+
+  OTP-14499    Application(s): crypto, erts
+               Related Id(s): ERL-251, ERL-439
+
+               On macOS, crypto would crash if observer had been
+               started before crypto. On the beta for macOS 10.13
+               (High Sierra), crypto would crash. Both of those bugs
+               have been fixed.

+
+  OTP-13704    Application(s): crypto, public_key

+
+               Extend crypto:sign, crypto:verify, public_key:sign and

+
+               * support for RSASSA-PS padding for signatures and for
+               saltlength setting
+               * X9.31 RSA padding.
+               * sha, sha224, sha256, sha384, and sha512 for dss
+               signatures as mentioned in NIST SP 800-57 Part 1.
+               * ripemd160 to be used for rsa signatures.

+ ---------------------------------------------------------------------
+
+ Note! The dialyzer-3.2.2 application can *not* be applied
+       independently of other applications on an arbitrary OTP 20
+       installation.
+
+       On a full OTP 20 installation, also the following runtime
+       dependency has to be satisfied:
+       -- hipe-3.16.1 (first satisfied in OTP 20.1)
+
+
+ --- Fixed Bugs and Malfunctions ---
+
+  OTP-14572    Application(s): dialyzer, hipe
+               Related Id(s): seq13319
+
+               Fix a bug regarding map types that caused Dialyzer to
+               go into an infinite loop. A consequence of the fix is
+               that compound map keys such as maps and tuples
+               sometimes are handled with less precision than before.
+
+
+ --- Improvements and New Features ---

+ ---------------------------------------------------------------------
+ --- diameter-2.1 ----------------------------------------------------
+ ---------------------------------------------------------------------
+
+ The diameter-2.1 application can be applied independently of other
+ applications on a full OTP 20 installation.
+
+ --- Fixed Bugs and Malfunctions ---
+
+  OTP-14011    Application(s): diameter
+
+               React to nodeup/nodedown when sharing peer connections.
+
+               Service configuration share_peers and use_shared_peers
+               did not respond to the coming and going of remote
+               nodes.
+
+
+  OTP-14486    Application(s): diameter
+
+               Fix inappropriate message callbacks.
+
+               An incoming CER or DPR was regarded as discarded,
+               resulting in a corresponding message callback (if
+               configured) in diameter_tcp/sctp.
+
+
+  OTP-14512    Application(s): diameter
+
+               Fix handling of 5009 errors
+               (DIAMETER_AVP_OCCURS_TOO_MANY TIMES).
+
+               RFC 6733 says that the first AVP that exceeds the bound
+               should be reported, but the suggestions in the errors
+               field of a diameter_packet record counted AVPs from the
+               rear of the message, not the front. Additionally,
+               diameter 2.0 in OTP 20.0 broke the counting by
+               accepting one more AVP than the message grammar in
+               question allowed.
+
+
+  OTP-14535    Application(s): diameter
+               Related Id(s): OTP-13006
+
+               Match case insensitively in diameter_tcp/sctp accept
+               tuple.
+
+               Matching of remote addresses when accepting connections
+               in a listening transport was case-sensitive, causing
+               the semantics to change as a consequence of (kernel)
+               OTP-13006.
+
+
+  OTP-14552    Application(s): diameter
+
+               Fix backwards incompatibility of remote send when
+               sharing transports.
+
+               The sending of requests over a transport connection on
+               a remote node running an older version of diameter was
+               broken by diameter 2.0 in OTP 20.0.
+
+
+  OTP-14607    Application(s): diameter
+
+               Fix diameter_packet.avps decode of Grouped AVP errors
+               in Failed-AVP.
+
+               Decode didn't produce a list of diameter_avp records,
+               so information about faulty component AVPs was lost.
+
+
+  OTP-9869     Application(s): diameter
+
+               Fix handling of Proxy-Info in answer messages setting
+               the E-bit.
+
+               RFC 6733 requires that Proxy-Info AVPs in an incoming
+               request be echoed in an outgoing answer. This was not
+               done in answers formulated by diameter; for example, as
+               a result of a handle_request callback having returned
+               an 'answer-message' or protocol_error tuple.
+
+
+ --- Improvements and New Features ---
+
+  OTP-10889    Application(s): diameter
+
+               Let unordered delivery be configured in diameter_sctp.
+
+               With option {unordered, boolean() | pos_integer()},
+               with false the default, and N equivalent to OS =< N,
+               where OS is the number of outbound streams negotiated
+               on the association in question. If configured,
+               unordered sending commences upon reception of a second
+               message, outgoing messages being sent on stream 0
+               before this.
+
+               The default false is for backwards compatibility, but
+               false or 1 should be set to follow RFC 6733's
+               recommendation on the use of unordered sending to avoid
+               head-of-line blocking. There is typically no meaningful
+               order to preserve, since the order in which outgoing
+               messages are received by a transport process isn't
+               known to the sender.

+
+
+  OTP-14511    Application(s): diameter
+               Related Id(s): OTP-14343
+
+               Add service option decode_format.
+
+               To allow incoming messages to be decoded into maps or
+               lists instead of records. Messages can be presented in
+               any of the formats for encode.
+
+               Decode performance has also been improved.
+
+
+  OTP-14521    Application(s): diameter
+
+               Add service option traffic_counters.
+
+               To let message-related counters be disabled, which can
+               be a performance improvement in some usecases.
+
+
+  OTP-14544    Application(s): diameter
+
+               Allow loopback/any as local addresses in
+               diameter_tcp/sctp.
+
+               The atoms were implied by documentation, but not
+               handled in code.
+
+
+  OTP-14546    Application(s): diameter
+
+               Add transport option strict_capx.
+
+               To allow the RFC 6733 requirement that a transport
+               connection be closed if a message is received before
+               capabilities exchange to be relaxed.
+
+
+  OTP-14555    Application(s): diameter
+
+               Be consistent with service/transport configuration.
+
+               For options for which it's meaningful, defaults values
+               for transport options can now be configured on a
+               service. This was previously the case only for an
+               arbitrary subset of options.
+
+
+  OTP-14588    Application(s): diameter
+
+               Add service/transport option avp_dictionaries.
+
+               To provide better support for AVPs that are not defined
+               in the application dictionary: configuring additional
