 ---------------------------------------------------------------------
 --- HIGHLIGHTS ------------------------------------------------------
 ---------------------------------------------------------------------

  OTP-14448    Application(s): crypto, ssl

               The crypto API is extended to use private/public keys
               stored in an Engine for sign/verify or encrypt/decrypt
               operations.

               The ssl application provides an API to use this new
               engine concept in TLS.


 ---------------------------------------------------------------------
 --- asn1-5.0.4 ------------------------------------------------------
 ---------------------------------------------------------------------

 The asn1-5.0.4 application can be applied independently of other
 applications on a full OTP 20 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-14786    Application(s): asn1
               Related Id(s): ERL-518

               There was a issue with BER encoding and the undec_rest
               option in generated decoders. An exception could be
               thrown instead of returning an error tuple.


  OTP-14787    Application(s): asn1
               Related Id(s): ERL-518

               The asn1ct:test functions crashed on decoders generated
               with options no_ok_wrapper, undec_rest.

 ---------------------------------------------------------------------
 --- common_test-1.15.3 ----------------------------------------------
 ---------------------------------------------------------------------

 The common_test-1.15.3 application can be applied independently of
 other applications on a full OTP 20 installation.

 --- Improvements and New Features ---

  OTP-13832    Application(s): common_test

               A new function, ct:remaining_test_procs/0, returns the
               identity of test- and group leader processes that are
               still running at the time of the call.


  OTP-14281    Application(s): common_test

               A "latest test result" link is now displayed in the
               footer of each test index page, which performs a jump
               to the most recently generated test index. This is
               useful for making quick comparisons of results between
               test runs without having to traverse the log file tree.

  OTP-14677    Application(s): erts

               Fix a bug in tracing where the {caller} match spec
               function would be set to undefined incorrectly when
               used in conjunction with return_to or return_trace on
               some functions.

               The functions effected are: erlang:put/2,
               erlang:erase/1, erlang:process_info/1,2,
               erlang:nif_load/2, erts_internal:garbage_collection/1
               and erts_internal:check_process_code/1.

               Because of this bug, the analysis done by fprof could
               become incorrect when the functions above are the
               tail-call in a function.


  OTP-14678    Application(s): erts

               Fix emulator deadlock that would happen if trap_exit
               was set to true and a process sends an exit signal to
               itself using exit(self(), Reason) while receive tracing
               was enabled for that process.

               Writing of crash dumps is significantly faster.

               Maps are now included in crash dumps.

               Constants terms would only be shown in one process,
               while other processes referencing the same constant
               term would show a marker for incomplete heap.


  OTP-14691    Application(s): erts

               The fallback home directory for windows has been
               changed to be the PROFILE directory instead of the
               WINDOWS directory. The fallback is used when the
               environment variables HOMEDRIVE and HOMEPATH have not
               been set.

               construction that could cause faulty result or even VM
               crash.

               On architectures other than x86_64, code need to be
               recompiled to benefit from this fix.


  OTP-14752    Application(s): erts

               Fixed bug in erlang:garbage_collect/2 and
               erlang:check_process_code/3, when called with option
               {async,ReqestId}. Could cause VM crash or heap
               corruption if RequestId was an immediate term (like a
               pid, atom or small integer). Bug exists since OTP-17.0.

               'ets:new/2') would crash the runtime system. Corrected.


  OTP-14796    Application(s): erts

               Setting the size of the atom table to a number near

               emulator to exit with a failure to allocate a huge
               amount of memory. This has been corrected. Also the
               usage message for the '+t' option has been corrected to
               show the correct upper limit 2147483647 instead of 0.


  OTP-14803    Application(s): erts

               Fixed a bug that prevented registered process names
               from being resolved in lcnt results.

  OTP-14689    Application(s): erts

               Micro optimization for send operations of messages to

               sent back from TPC/IP port driver to sending client

               In order to allow future improvements, Crashdump Viewer
               now checks the version tag of the crashdump to see that
               it is a known format. If the crashdump version is newer
               than Crashdump Viewer is prepared to read, then an
               information dialog is displayed before Crashdump Viewer
               terminates.

               If an incomplete process heap is discovered in a
               crashdump, Crashdump Viewer will now display a warning
               for this, similar to the warning displayed when a
               crashdump is truncated. Incomplete heaps can occur if
               for instance the literals are not included, which is
               the case for all dumps prior to OTP-20.2.

               allowed as input to error_logger, but rb would state
               that "A report on bad form was encountered". This is
               now corrected.

 Note! The ssh-4.6.3 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
       dependencies have to be satisfied:
       -- crypto-4.2 (first satisfied in OTP 20.2)
       -- public_key-1.5.2 (first satisfied in OTP 20.2)

  OTP-14602    Application(s): ssh

               Passphrase option for ecdsa public keys was missing.


 --- Improvements and New Features ---

  OTP-14676    Application(s): ssh
               Related Id(s): ERIERL-52, OTP-14570

               The host and user public key handling is hardened so
               that a faulty plugin can't deliver a key of wrong type.

               Better checks in the server of the available hostkey's
               types at start and at each accept.

               Better checks in the client of the available user
               public key types at connect.


  OTP-14757    Application(s): ssh

               SSH can now fetch the host key from the private keys
               stored in an Engine. See the crypto application for
               details about Engines.

               will not be supported.

               Ensure data delivery before close if possible. This fix
               is related to fix in PR-1479.


 --- Improvements and New Features ---

  OTP-14448    Application(s): crypto, ssl

               *** HIGHLIGHT ***

               The crypto API is extended to use private/public keys
               stored in an Engine for sign/verify or encrypt/decrypt
               operations.

               The ssl application provides an API to use this new
               engine concept in TLS.


  OTP-14563    Application(s): ssl

               Implemented renegotiation for DTLS


  OTP-14657    Application(s): ssl

               A new command line option -ssl_dist_optfile has been
               added to facilitate specifying the many options needed
               when using SSL as the distribution protocol.
