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

   OTP-10279  == erts ==

	      Support for migration of memory carriers between memory

	      allocator instances has been introduced.

	      By default this feature is not enabled and do not effect the

	      characteristics of the system. When enabled it has the

	      following impact on the characteristics of the system:

	      -- Reduced memory footprint when the memory load is unevenly

	      distributed between scheduler specific allocator instances.

	      -- Depending on the default allocaton strategy used on a

	      specific allocator there might or might not be a slight

	      performance loss.

	      -- When enabled on the fix_alloc allocator, a different

	      strategy for management of fix blocks will be used.

	      -- The information returned from

	      erlang:system_info({allocator, A}), and

	      erlang:system_info({allocator_sizes, A}) will be slightly

	      different when this feature has been enabled. An mbcs_pool

	      tuple will be present giving information about abandoned

	      carriers, and in the fix_alloc case no fix_types tuple will

	      be present.

	      For more information, see the documentation of the +M<S>acul

	      command line argument.

	      Integrate elliptic curve contribution from Andreas Schultz 

	      In order to be able to support elliptic curve cipher suites

	      in SSL/TLS, additions to handle elliptic curve infrastructure

	      has been added to public_key and crypto.

	      This also has resulted in a rewrite of the crypto API to gain

	      applications using crypto has been updated to use the new

	      API.

	      Impact: Elliptic curve cryptography (ECC) offers equivalent

	      security with smaller key sizes than other public key

	      algorithms. Smaller key sizes result in savings for power,

	      memory, bandwidth, and computational cost that make ECC

	      especially attractive for constrained environments.

--- otp -----------------------------------------------------------------

   OTP-11117  Properly ignore os_mon and otp_mibs generated includes

--- asn1-2.0.1.1 --------------------------------------------------------

   OTP-10916  The generated decoder for the 'per' and 'uper' backends 

              did not correctly decode ENUMERATEDs with a single value. 

              The generated encoder for the 'per' and 'uper' backends 

              generated an empty binary for a top-level type that did 

              not need to be encoded (such as an ENUMERATED with a single 

              value). The correct result should be a binary containing 

              a 0 byte.

--- asn1-2.0.1.2 --------------------------------------------------------

   OTP-10995  When an object set is an actual parameter, the extension 

              marker for the object set could get lost (which would cause 

              the decoding of unknown values to fail).

--- asn1-2.0.2 ----------------------------------------------------------

   OTP-11016  Postscript files no longer needed for the generation of PDF

	      files have been removed.

   OTP-11111  Fix some Makefile rules that didn't support silent rules.

	      Thanks to Anthony Ramine.

   OTP-11134  PER/UPER: A semi-constrained INTEGER with a non-zero lower

	      bound would be incorrectly decoded. This bug was introduced

	      in R16.

	      PER/UPER: Given INTEGER (10..MAX, ...), attempting to decode

	      any integer below 10 would cause the encoder to enter an

	      infinite loop.

	      PER/UPER: For a type with an extensible SIZE constraint,

	      sizes outside of the root range were incorrectly encoded.

	      Given a constraint such as (SIZE (5, ...)), encoding a size

	      less than 5 would fail (PER/UPER). Similarly, for BER

	      decoding would fail.

	      PER: The encoder did not align a known multiplier string

	      (such as IA5String) of length 16 bits (exactly) to an octet

	      boundary.

	      In rare circumstances, DEFAULT values for the UPER backend

	      could be wrongly encoded.

   OTP-11153  UPER: The compiler would crash when compiling an ENUMERATED

	      having more than 63 extended values.

	      PER/UPER: A SEQUENCE with more 64 extended values could not

	      be decoded.

   OTP-11154  When decoding a SEQUENCE defined inline inside a an extension

	      addition group, the record named generated by the decoding

	      code would not match the name in the generated .hrl file.

--- common_test-1.7.2 ---------------------------------------------------

   OTP-10126  A design flaw in the generic connection handling in Common

	      Test made it impossible to implement a connection handler

	      that could map multiple connection names (i.e. configuration

	      variable aliases) to single connection pids. This problem has

	      been solved.

   OTP-10494  If it could not be decided which test case a certain log

	      printout belonged to, the common test framework log was

	      earlier used. Such printouts are now instead sent to

	      unexpected_io.log.html in test_server so that there is only

	      one place to look for "missing" printouts.

   OTP-10648  If a telnet connection is hanging, then a call to

	      ct_telnet:close/1 will time out after 5 seconds and the

	      connection process is brutally killed. In some cases the

	      connection would not be unregistered and attempts at opening

	      a new connection with the same name would make common_test

	      try to reuse the same connection since it believed that it

	      was still alive. This has been corrected - a killed

	      connection is now always unregistered.

   OTP-10855  Test performance has been improved by means of a cache for

	      the top level HTML index logs (all_runs.html and index.html,

	      in the logdir directory). This solves problems with slow

	      start up times and test execution times increasing with the

	      number of ct_run directories stored in logdir. The cached

	      index entries are stored in RAM during test execution and are

	      saved to file in logdir (for faster start up times) whenever

	      a test run finishes.

   OTP-10856  The '-force_stop' flag to use with time-limited repeats of

	      test runs can now be used with a new 'skip_rest' option which

	      causes the rest of the test cases in the ongoing test job to

	      be skipped when the time limit is reached. E.g. 'ct_run -spec

	      xxx -duration 010000 -force_stop skip_rest'

   OTP-10857  Testing of the test specification functionality has been

	      improved and a couple of minor bugs have been discovered and

	      corrected.

   OTP-10902  Make cover smarter about finding source from beam.

	      In particular, search using the source path in module_info if

	      the current heuristic fails.

   OTP-10920  Add a variant of ct_slave:start/2 that starts a node with

	      specified options on the local host.

   OTP-11009  Integrate elliptic curve contribution from Andreas Schultz 

	      In order to be able to support elliptic curve cipher suites

	      in SSL/TLS, additions to handle elliptic curve infrastructure

	      has been added to public_key and crypto.

	      This also has resulted in a rewrite of the crypto API to gain

	      consistency and remove unnecessary overhead. All OTP

	      applications using crypto has been updated to use the new

	      API.

	      Impact: Elliptic curve cryptography (ECC) offers equivalent

	      security with smaller key sizes than other public key

	      algorithms. Smaller key sizes result in savings for power,

	      memory, bandwidth, and computational cost that make ECC

	      especially attractive for constrained environments.

   OTP-11016  Postscript files no longer needed for the generation of PDF

	      files have been removed.

   OTP-11044  A link is added from the red error printout in a test case

	      log (for a failed test case) to the full error description at

	      the end of the log. The reason for this is that the error

	      description in the red field is sometimes truncated at 50

	      characters in order to keep the log as short and easy to read

	      as possible.

   OTP-11046  Links to the top level index files in some HTML footers had

	      disappeared. This error has been corrected. Also, a problem

	      with the suite overview log file not being closed properly

	      has been solved.

   OTP-11052  Common Test would, in case of timetrap error, print a warning

	      in the log if end_per_testcase wasn't implemented in the

	      suite, even though it's an optional function. This printout

	      has been removed.

   OTP-11095  A new option 'no_prompt_check' is added to

	      ct_telnet:expect/3. If this option is used, ct_telnet will

	      not wait for a prompt or a newline before attempting to match

	      the given pattern.

--- compiler-4.9.2 ------------------------------------------------------

   OTP-10939  Compiling functions with complex boolean operations in guards

	      could be very slow. (Thanks to Magnus Muller for reporting

	      this issue.)

   OTP-11005  Fix optimization of some binary comprehensions. Thanks to

	      Anthony Ramine.

   OTP-11069  Use a set to store ref registers in beam_receive. Thanks to

	      Anthony Ramine.

   OTP-11119  Certain guard expressions used in a receive statement could

	      cause the compiler to crash.

   OTP-11129  Fix renaming of bs_put_string instructions. Thanks to Anthony

	      Ramine.

--- cosEvent-2.1.14 -----------------------------------------------------

   OTP-11016  Postscript files no longer needed for the generation of PDF

	      files have been removed.

--- cosFileTransfer-1.1.15 ----------------------------------------------

   OTP-11016  Postscript files no longer needed for the generation of PDF

	      files have been removed.

--- cosNotification-1.1.20 ----------------------------------------------

   OTP-11016  Postscript files no longer needed for the generation of PDF

	      files have been removed.

--- crypto-3.0 ----------------------------------------------------------

   OTP-11009  Integrate elliptic curve contribution from Andreas Schultz 

	      In order to be able to support elliptic curve cipher suites

	      in SSL/TLS, additions to handle elliptic curve infrastructure

	      has been added to public_key and crypto.

	      This also has resulted in a rewrite of the crypto API to gain

	      consistency and remove unnecessary overhead. All OTP

	      applications using crypto has been updated to use the new

	      API.

	      Impact: Elliptic curve cryptography (ECC) offers equivalent

	      security with smaller key sizes than other public key

	      algorithms. Smaller key sizes result in savings for power,

	      memory, bandwidth, and computational cost that make ECC

	      especially attractive for constrained environments.

   OTP-11058  Fixed a spelling mistake in crypto docs. Thanks to Klaus

	      Trainer

--- debugger-3.2.11 -----------------------------------------------------

   OTP-10899  A new checkbox has been added. When it is checked, the range

	      set by the erl flag +pc is used for determining when to print

	      lists of integers as strings. When it is unchecked, integer

	      lists are never printed as strings.

	      A minor incompatibility: settings saved by Erlang R16B01 or

	      later cannot be read by Erlang R16B or earlier.

   OTP-11041  Erlang source files with non-ASCII characters are now encoded

	      in UTF-8 (instead of latin1).

--- dialyzer-2.6.1 ------------------------------------------------------

   OTP-10918  Include module, function and arity in Dialyzer's "overlapping

	      domain" warnings. Thanks to Magnus Henoch.

   OTP-10996  Improve Dialyzer output for scan errors. Thanks to Magnus

	      Henoch.

   OTP-11009  Integrate elliptic curve contribution from Andreas Schultz 

	      In order to be able to support elliptic curve cipher suites

	      in SSL/TLS, additions to handle elliptic curve infrastructure

	      has been added to public_key and crypto.

	      This also has resulted in a rewrite of the crypto API to gain

	      consistency and remove unnecessary overhead. All OTP

	      applications using crypto has been updated to use the new

	      algorithms. Smaller key sizes result in savings for power,

	      memory, bandwidth, and computational cost that make ECC

	      especially attractive for constrained environments.

   OTP-11027  Bitstring type inference and duplicate module error message

	      fixes. Thanks to Stavros Aronis.

   OTP-11041  Erlang source files with non-ASCII characters are now encoded

	      in UTF-8 (instead of latin1).

   OTP-11057  A bug that made it impossible to do any analyses from the GUI

	      has been fixed.

--- diameter-1.4.1.1 ----------------------------------------------------

   OTP-10898  Add transport_opt() watchdog_config to allow non-standard 

              behaviour of the watchdog state machine. This can be useful 

              during test but should not be used on nodes that must conform 

              to RFC 3539. 

   OTP-10942  Fix broken Vendor-Specific-Application-Id configuration. 

              RFC 6733 changed the definition of this Grouped AVP, changing 

              the arity of Vendor-Id from 1* to 1. A component Vendor-Id 

              can now be either list- or integer-valued in service and 

              transport configuration, allowing it to be used with both 

              RFC 3588 and RFC 6733 dictionaries.

--- diameter-1.4.2 ------------------------------------------------------

    OTP-9610  Allow peer connections to be shared between Erlang nodes for

	      the purpose of sending outgoing requests.

	      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.

   OTP-10893  Allow listening diameter_{tcp,sctp} transports to be

	      configured with remote addresses.

	      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.

   OTP-10972  Detect more transport_opt() configuration errors at

	      diameter:add_transport/2.

	      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.

   OTP-10986  Make explicit local address configuration optional in

	      diameter_tcp:start/3.

	      The default address (as determined by gen_tcp) is now used

	      when a local address is not explicitly configured.

   OTP-11007  Fix handling of 5014 (INVALID_AVP_LENGTH) errors.

	      This was in some cases reported as 3009 (INVALID_AVP_BITS).

	      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.

   OTP-11014  Fix faulty capitalization in release notes.

	      Diameter = the protocol.
 diameter = the Erlang

	      application.

   OTP-11017  Improve handling of unrecognized service options.

	      Such options were silently ignored by

	      diameter:start_service/2. An error tuple is now returned.

   OTP-11019  Fix watchdog memory leak.

	      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.

	      The fault was introduced by OTP-10692 in diameter-1.4.1

	      (R16B).

   OTP-11026  Fix decode failure on AVP Length < 8.

	      The failure caused the message in question to be discarded.

   OTP-11045  Respect Host-IP-Address configuration.

	      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.

   OTP-11050  Don't send default Inband-Security-Id in CER/CEA.

	      RFC 6733 recommends against the use of Inband-Security-Id.

	      Only send a value that differs from the default,

	      NO_INBAND_SECURITY = 0.

   OTP-11051  Fix mkdir race.

	      Install could fail if examples/code and examples/dict were

	      created in parallel. Noticed on FreeBSD.

   OTP-11060  Make spawn options for request processes configurable.

   OTP-11087  Fix recognition of 5001 on mandatory AVP's.

	      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.

	      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.

   OTP-11092  Fix setting of Failed-AVP on handle_request {answer_message,

	      5xxx} return.

	      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.

   OTP-11115  Fix watchdog function_clause

	      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.

	      Thanks to Aleksander Nycz.

   OTP-11127  Fix population of Failed-AVP.

	      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.

   OTP-11165  Fix list-valued Vendor-Specific-Application-Id config

	      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.

--- erl_interface-3.7.12 ------------------------------------------------

   OTP-10913  Superfluous trailing comma in enum erlang_char_encoding 

              causing compile error for g++ with --pedantic option.

--- erl_interface-3.7.13 ------------------------------------------------

   OTP-11167  A guard was added to check if file descriptor is valid before

	      closing it.

--- erts-5.10.1.1 -------------------------------------------------------

   OTP-10926  The BIF is_process_alive/1 could prematurely return false 

              while the process being inspected was terminating. This 

              bug was introduced in ERTS-5.10. 

   OTP-10932  Fix a problem in erlang:delete_element/2 where the call 

              could corrupt one word of stack if the heap and stack met 

              during call. 

   OTP-10994  Scheduler threads will now by default be less eager requesting 

              wakeup due to certain cleanup operations. This can also 

              be controlled using the +swct command line argument of erl(1). 

   OTP-11000  The +sws<value> and +swt<value> system flags 

              failed if no white space were passed between the parameter 

              and value parts of the flags. Upon failure, the runtime 

              system refused to start.

--- erts-5.10.1.2 -------------------------------------------------------

   OTP-11022  A bug in the implementation of offline schedulers has been 

              fixed. The bug was introduced in OTP-R16A/ERTS-5.10, and 

              caused work-stealing between schedulers to fail. This in 

              turn, caused work to accumulate in some run-queues. The 

              bug was only triggered when there were offline schedulers 

              in the system, i.e., when the amount of online schedulers 

              was less than the total amount of schedulers. The effect 

              of the bug got more severe the larger amount of offline 

              schedulers the system had.

--- erts-5.10.2 ---------------------------------------------------------

   OTP-10271  Replaced the lock protecting gathering of garbage collection

	      statistics with a lock-free solution.

   OTP-10279  Support for migration of memory carriers between memory

	      allocator instances has been introduced.

	      By default this feature is not enabled and do not effect the

	      characteristics of the system. When enabled it has the

	      following impact on the characteristics of the system:

	      -- Reduced memory footprint when the memory load is unevenly

	      distributed between scheduler specific allocator instances.

	      -- Depending on the default allocaton strategy used on a

	      specific allocator there might or might not be a slight

	      performance loss.

	      -- When enabled on the fix_alloc allocator, a different

	      strategy for management of fix blocks will be used.

	      -- The information returned from

	      erlang:system_info({allocator, A}), and

	      erlang:system_info({allocator_sizes, A}) will be slightly

	      different when this feature has been enabled. An mbcs_pool

	      tuple will be present giving information about abandoned

	      carriers, and in the fix_alloc case no fix_types tuple will

	      be present.

   OTP-10497  A bug in prim_inet has been corrected. If the port owner was

	      killed at a bad time while closing the socket port the port

	      could become orphaned hence causing port and socket leaking.

	      Reported by Fred Herbert, Dmitry Belyaev and others.

   OTP-10941  Compilation fixes for NetBSD. Thanks to YAMAMOTO Takashi.

   OTP-10984  Fixed a race condition when using delayed_write when writing

	      to a file which would cause the same data to be written

	      multiple times.

   OTP-10997  Fix small memory leak from tracing with option meta.

   OTP-11002  Correct typo in erlsrv usage. Thanks to Bryan Hunter

   OTP-11003  ct_run: delete unused function. Thanks to Tuncer Ayaz.

   OTP-11008  Change specs for spawn_opt to use the process_level() type

	      declaration instead of re-defining it in various places.

	      Thanks to Kostis Sagonas.

   OTP-11012  Corrections to run_erl/to_erl handshake behaviour.

   OTP-11016  Postscript files no longer needed for the generation of PDF

	      files have been removed.

   OTP-11024  Fix typo in type: erlang:process_info_item(). Thanks to

	      Andrew Tunnell-Jones.

   OTP-11041  Erlang source files with non-ASCII characters are now encoded

	      in UTF-8 (instead of latin1).

   OTP-11064  Fix src/dest overlap issue in ttsl driver. Thanks to Steve

	      Vinoski.

   OTP-11074  Optimization of simultaneous inet_db operations on the same

	      socket by using a lock free implementation.

	      Impact on the characteristics of the system: Improved

	      performance.

   OTP-11075  The high_msgq_watermark and low_msgq_watermark inet socket

	      options introduced in OTP-R16A could only be set on TCP

	      sockets. These options are now generic and can be set on all

	      types of sockets.

   OTP-11076  When sending to a port using erlang:send(Port, Msg,

	      [nosuspend]), the send operation was performed synchronously.

	      This bug has now been fixed.

   OTP-11077  A new better algorithm for management of the process, and

	      port tables has been introduced.

	      Impact on the characteristics of the system:

	      -- The new algorithm ensures that both insert and delete

	      operations can be made in O(1) time complexity. Previously

	      used algorithm either caused insert or delete to be O(N).

	      -- The new algorithm will also ensure that reuse of

	      identifiers will be less frequent than when the old algorithm

	      was used.

	      -- Previously used algorithm ensured that the latest created

	      identifier compared as the largest when comparing two

	      identifiers of the same type that had been created on the

	      same node as long as no identifiers had been reused. Since

	      identifiers can be reused quite fast, one has never been able

	      to rely on this property. Due to the introduction of this new

	      algorithm this property will not hold even if no identifiers

	      has been reused yet. This could be considered as an

	      incompatibility.

	      Due to the above mensioned potential incompatibility, it will

	      still be possible to enable the old algorithm for some time.

	      The command line argument +P legacy will enable the old

	      algorithm on the process table, and +Q legacy will do the

	      same for the port table. These command line arguments are

	      however deprecated as of their introduction and have been

	      scheduled for removal in OTP-R18.

   OTP-11080  When converting a faulty binary to a list with

	      unicode:characters_to_list, the error return value could

	      contain a faulty "rest", i.e. the io_list of characters that

	      could not be converted was wrong. This happened only if input

	      was a sub binary and conversion was from utf8. This is now

	      corrected.

   OTP-11084  Runtime system could crash when reporting stale

	      driver_select().

   OTP-11085  Fix lock order violation for memory instrumentation (+Mim,

	      +Mis, +Mit).

   OTP-11086  Fixed some compilation warnings on miscellaneous platforms.

	      Thanks to Anthony Ramine.

   OTP-11088  Support wide characters in the shell through wcwidth().

	      Thanks to Anthony Ramine. Reported by Loïc Hoguin.

   OTP-11096  Fixed issue when flushing i/o during shutdown on windows

	      where the Erlang VM would sometime hang due to a race

	      condition.

   OTP-11097  Fixed issue where repeated calls to erlang:nodes() could

	      cause unnecessary contention in the dist_table lock.

   OTP-11098  Added total used memory for each process in erlang crash

	      dumps.

   OTP-11106  Properly guard WIDE_TAG use with HAVE_WCWIDTH in ttsl_drv.

	      Thanks to Anthony Ramine

	      Thanks to Anthony Ramine.

   OTP-11125  Added support for hipe on Raspberry Pi (armv6l). Thanks to

	      Klaus Alfert.

   OTP-11137  Fix receive support in erl_eval with a BEAM module. Thanks to

	      Anthony Ramine.

   OTP-11146  erlang:now() could suddenly jump ~24 days into the future on

	      Windows. This is now corrected. Thanks to Garret Smith for

	      reporting and testing fixes.

   OTP-11158  Remove 'query' from the list of reserved words in docs.

	      Thanks to Matthias Endler and Loïc Hoguin.

   OTP-11159  Lift static limitation (FD_SETSIZE) for file descriptors on

	      Mac OS X. (Thanks to Anthony Ramine)

   OTP-11163  erlang:term_to_binary will now cost an appropriate amount of

	      reductions and will interrupt (yield) for reschedule if the

	      term is big. This avoids too long schedules when
