 --- Fixed Bugs and Malfunctions ---

  OTP-16052    Application(s): erts, stdlib

               The functions unicode:characters_to_list() and
               unicode:characters_to_binary() raised a badarg
               exception instead of returning an error tuple when
               passed very large invalid code points as input.


  OTP-16074    Application(s): erts
               Related Id(s): ERL-1042, PR-2386

               file:allocate/3 will now work properly on Mac OS.


  OTP-16149    Application(s): erts

               For socket, invalid encoding of send and receive flags
               caused badarg and send failure.


  OTP-16150    Application(s): erts
               Related Id(s): ERL-1043

               Fix a bug in re on platforms where the native stack
               grows upwards, for instance on HP PA-RISC.


  OTP-16151    Application(s): erts
               Related Id(s): #2400

               For socket, unable to properly decode the timestamp
               control message header on FreeBSD. We incorrectly used
               the SO_TIMESTAMP flag for the timestamp control message
               header type. It should have been SCM_TIMESTAMP. This
               caused the timestamp control message header to not be
               fully decoded.


  OTP-16152    Application(s): erts
               Related Id(s): OTP-16114

               For socket, when setting the ip option 'recvtos' to
               true, thereby indicating that we want to receive the
               TOS control message header, we don't actually get TOS
               but RECVTOS on FreeBSD (and maybe others)! This was
               previously not handled.


  OTP-16159    Application(s): erts
               Related Id(s): ERL-1060

               Fixed a bug where the emulator would print out error
               messages forever if it crashed during startup.


  OTP-16163    Application(s): erts
               Related Id(s): ERL-1061

               For socket, wrong type for protocol caused segmentation
               fault if protocol was provided as {raw, integer()}.


  OTP-16172    Application(s): erts
               Related Id(s): OTP-16114

               For socket, when setting the ip option 'recvttl' to
               true, thereby indicating that we want to receive the
               TTL control message header, we don't actually get TTL
               but RECVTTL on Solaris (and maybe others)! This was
               previously not handled.


  OTP-16173    Application(s): erts

               For socket, IPv6 control message headers was
               incorrectly decoded with level ip instead of ipv6.


  OTP-16191    Application(s): erts
               Related Id(s): ERL-1067

               Fix configure bug where clock_getres would not
               correctly be detected causing
               erlang:system_info(os_system_time_source) to return an
               incorrect resolution.

               This bug effects all OSs that use clock_gettime to get
               time (basically all OSs except windows) and has been
               present since OTP-19.2.


  OTP-16192    Application(s): erts

               Fix bugs when using ERLC_USE_SERVER=true on Windows
               when building Erlang/OTP.

               Change the cookie used by the compile server to be hard
               coded instead of using the users cookie.


  OTP-16194    Application(s): erts

               Fix so that persistent_term is listed in the erts
               application file.


  OTP-16195    Application(s): erts
               Related Id(s): ERL-1027

               Fix bug in call_time tracing which could sometimes
               cause call time measurements being attributed to the
               wrong function.


  OTP-16196    Application(s): erts

               The socket socket option 'peek_off' has been disabled.
               If peek_off was set and then socket:recv/3 was called
               with the peek flag, the call could hang.


  OTP-16197    Application(s): erts

               Handle possibly uninitiated (control message header)
               data.


  OTP-16203    Application(s): erts

               For net, a couple of NI macros was deprecated in new
               versions of glibc, so these are no longer used
               (IDN_ALLOW_UNASSIGNED and IDN_USE_STD3_ASCII_RULES).


  OTP-16204    Application(s): erts

               The string value from a get operation needed to be
               truncated.


  OTP-16206    Application(s): erts
               Related Id(s): PR-2423

               Fix misleading seq_trace message for remote send
               operation toward named process. Changed receiver to be
               {Name,Node} instead of just Name.


  OTP-16216    Application(s): erts, kernel

               Fixed a bug causing actual nodedown reason reported by
               net_kernel:monitor_nodes(true, [nodedown_reason]) to be
               lost and replaced by the reason killed.


  OTP-16223    Application(s): erts

               For socket, the timestamp creation used when printing
               warning messages and debug printouts did not work. The
               used buffer was too small.


  OTP-16235    Application(s): erts

               Fix compiler warnings generated by GCC 8


  OTP-16297    Application(s): erts

               Fix erl -emu_type to accept the option opt which means
               the normal optimized emulator. This can be used to
               override the -emu_type option from environment
               variables.


  OTP-16310    Application(s): erts
               Related Id(s): ERL-1082

               Corrected the function spec to reflect the actual code
               of the function socket:bind.


  OTP-16316    Application(s): erts, stdlib

               Fixed a performance issue in ETS lookup when using the
               compressed option and the term contained atoms. Before
               this fix the decompress algorithm for atoms would
               unnecessarily take a global lock to validate the atom.


 --- Improvements and New Features ---

  OTP-16153    Application(s): erts

               For socket, not all send and receive flags are
               supported on all platforms. In order to (at least)
               simplify testing, the socket:supports/0,1,2,3 functions
               has been extended with send_flags and recv_flags items,
               which indicates what the current platform can manage.


  OTP-16180    Application(s): erts

               For socket, add support for IPv6 socket options tclass
               and recvtclass. Both has been added, but the use of
               them are platform dependent. Call
               socket:supports(options, ipv6, Opt) to be sure what
               option to use in order to request a TCLASS control
               message header.


  OTP-16205    Application(s): erts

               For socket, the TCP socket option cork was not
               supported even though the supports function reported it
               as such.


  OTP-16208    Application(s): erts

               *** HIGHLIGHT ***

               The Kernel application's User's Guide now contain a
               Logger Cookbook with with common usage patterns.


  OTP-16212    Application(s): erts
               Related Id(s): ERL-1070

               Add a "full featured" version of getifaddrs in the net

               The ssh cli (e.g shell) server behaved strangely when
               characters were inserted in a string such that the last
               characters tried to wrap the line.


  OTP-15417    Application(s): ssh
               Related Id(s): OTP-16108

               If an OTP SSH server was serving an "exec" request and
               the executed code used Erlang standard_io for
               input/output, the I/O was erroneously handled by the
               *server's* group leader, so the I/O turned up in the
               the server's Erlang shell (if any). The user at the
               client side did therefor not see that I/O.

               This is corrected now, so the client - for example the
               ssh OS shell command - handles the I/O. The user could
               send input to the server side exec handling code by
               writing on the terminal, and server side output from
               for example io:format is presented on the terminal -
               not only the functional result.

               NOTE 1: Servers executing exec requests with the old,
               undocumented ways of specifying the custom exec handler
               is not changed. Changed are only the two cases where
               the server's 'exec' option either:
               1) is not specified (i.e. using the default shell) or,
               2) it has the {direct, fun(...) -> ... end} value
               format.

               NOTE 2: Previously an end-of-line marker was appended
               on the result and error reports at the client side.
               They are removed now and the error reports are slightly
               enhanced.

               TECHNICAL DETAILS: The server's device standard_input
               receives data events from the exec request's channel,
               and the device standard_output is sending its data by
               data events to the client on that channel. The result
               is that standard_io is now performed by the client's
               group leader.

               an exec request.

               The mac 'hmac-sha1-96' is nowadays not recommended and

 --- Improvements and New Features ---

  OTP-16339    Application(s): xmerl

               Implement handling of parsed entity content and some
               other improvements.

               -- Updated the SAX test-suite (xmerl_sax_std_SUITE) to
               more recent version

               -- Test now uses its own data directory since the
               non-SAX xmerl test suite (xmerl_std_SUITE) uses a
               different version of the other suite

               -- Canonical XML checks have been added to all tests
               that apply. Canonical, as it applies here, is regular
               canonical XML with the addition of notation
               declarations if any. Output must match byte-for-byte.

               -- External entities implemented, both as markup and
               replacement text

               -- Cyclic references are checked at the end of the DTD
               parse; also when a reference is found

               -- Default attributes are reported in events

               -- Attributes are whitespace normalized if their type
               demands it

               -- External entities can have a different encoding than
               the base document and will be transcoded to the
               document encoding

               -- Conditional sections (IGNORE/INCLUDE) handling has
               been added to DTD parsing

               -- Element content-model is now checked for
               well-formed-ness

               -- A few missing function clauses have been added
