+ ---------------------------------------------------------------------
+
+  OTP-15133    Application(s): ssh
+               Related Id(s): OTP-15240
+
+               The key exchange methods
+               '[email protected]', 'curve25519-sha256' and
+               'curve448-sha512' are implemented. The last two are
+               defined in
+               https://tools.ietf.org/html/draft-ietf-curdle-ssh-curves
+
+               They all depends on that OpenSSL 1.1.1 or higher is
+               used as cryptolib.
+
+
+  OTP-15134    Application(s): crypto, public_key
+
+               The typing in the CRYPTO and PUBLIC_KEY applications
+               are reworked and a few mistakes are corrected.
+
+               The documentation is now generated from the typing and
+               some clarifications are made.
+
+               A new chapter on Algorithm Details such as key sizes
+               and availability is added to the CRYPTO User's Guide.
+
+
+  OTP-15145    Application(s): erts, kernel
+               Related Id(s): ERIERL-187
+
+               The socket options recvtos, recvttl, recvtclass and
+               pktoptions have been implemented in the socket modules.
+               See the documentation for the gen_tcp, gen_udp and inet
+               modules. Note that support for these in the runtime
+               system is platform dependent. Especially for pktoptions
+               which is very Linux specific and obsoleted by the RFCs
+               that defined it.
+
+
+  OTP-15209    Application(s): ssh
+               Related Id(s): OTP-15164
+
+               The cipher '[email protected]' is now
+               supported if OpenSSL 1.1.1 or higher is used as
+               cryptolib.

+ ---------------------------------------------------------------------
+
+ The asn1-5.0.7 application can be applied independently of other
+ applications on a full OTP 21 installation.
+
+ --- Fixed Bugs and Malfunctions ---
+
+  OTP-14440    Application(s): asn1
+               Related Id(s): ERIERL-220
+
+               A bug in ASN.1 BER decoding has been fixed. When
+               decoding a recursively enclosed term the length was not
+               propagated to that term decoding, so if the length of
+               the enclosed term was longer than the enclosing that
+               error was not detected.
+
+               A hard coded C stack limitation for decoding recursive
+               ASN.1 terms has been introduced. This is currently set
+               to 8 kWords giving a nesting depth of about 1000
+               levels. Deeper terms can not be decoded, which should
+               not be much of a real world limitation.

+ ---------------------------------------------------------------------
+
+ The common_test-1.16.1 application can be applied independently of
+ other applications on a full OTP 21 installation.
+
+ --- Fixed Bugs and Malfunctions ---
+
+  OTP-15307    Application(s): common_test
+
+               The Logger handler cth_log_redirect earlier called the
+               report callback (report_cb) before calling the logger
+               formatter. In some cases this would fail, since
+               cth_log_redirect could not handle report callbacks with
+               two arguments. This is now corrected, so only the
+               formatter will call the report callback.
+
+
+ Full runtime dependencies of common_test-1.16.1: compiler-6.0,
+ crypto-3.6, debugger-4.1, erts-7.0, ftp-1.0.0, inets-6.0, kernel-4.0,

+
+ The compiler-7.2.5 application can be applied independently of other
+ applications on a full OTP 21 installation.
+
+ --- Fixed Bugs and Malfunctions ---
+
+  OTP-15186    Application(s): compiler
+               Related Id(s): ERL-665
+
+               Fixed a bug that prevented certain variable-sized
+               binary comprehensions from compiling.
+
+
+  OTP-15188    Application(s): compiler
+               Related Id(s): ERL-658
+
+               When compiling from Core Erlang, funs created in
+               certain expressions that were only used for their
+               side-effects were subtly broken.
+
+
+  OTP-15218    Application(s): compiler
+               Related Id(s): ERL-684
+
+               There could be an internal consistency failure when a
+               receive was nested in a try/catch.
+
+
+  OTP-15219    Application(s): compiler
+               Related Id(s): ERL-689
+
+               In rare circumstances, the matched out tail of a binary
+               could be the entire original binary.
+
+
+  OTP-15227    Application(s): compiler
+               Related Id(s): ERL-699
+
+               When is_map_key/2 was used in a guard together with the
+               not/1 or or/2 operators, the error behavior could be
+               wrong when is_map_key/2 was passed a non-map as the
+               second argument.
+
+               In rare circumstances, compiling code that uses
+               is_map_key/2 could cause an internal consistency check
+               failure.
+
+
+  OTP-15235    Application(s): compiler
+               Related Id(s): ERL-703
+
+               The compiler could crash when compiling a function with
+               multiple receives in multiple clauses.

+
+  OTP-15212    Application(s): crypto
+               Related Id(s): ERL-675, PR1899, PR838
+
+               The RSA options rsa_mgf1_md, rsa_oaep_md, and
+               rsa_oaep_label were always disabled. They will now be
+               enabled when a suitable cryptolib is used.
+
+               They are still experimental and may change without
+               prior notice.
+
+
+  OTP-15283    Application(s): crypto
+
+               The ciphers aes_ige256 and blowfish_cbc had naming
+               issues in crypto:next_iv/2.
+
+
+  OTP-15303    Application(s): crypto
+
+               the RSA_SSLV23_PADDING is disabled if LibreSSL is used
+               as cryptlib. This is due to compilation problems.
+
+               This will be investigated further in the future.

+
+               The conversion aborted completely midway because the
+               ATL contained invalid entries. The conversion has been

+
+               The reason the ATL contained invalid entries have also
