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

   OTP-10279  == erts ==

	      Support for migration of memory carriers between memory
	      allocator instances has been introduced. For more information
	      see the documentation of the +M<S>acul command line argument.

	      When enabling this feature 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-11009  == ssl public_key crypto common_test dialyzer ssh stdlib snmp
	      inets ==

	      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-11159  == erts ==

	      Lift static limitation (FD_SETSIZE) for file descriptors on
	      Mac OS X. (Thanks to Anthony Ramine)

--- POTENTIAL INCOMPATIBILITIES -----------------------------------------

   OTP-11077  == erts ==

	      A new algorithm for management of the process, and port
	      tables has been introduced. 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 this 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.

--- asn1 ----------------------------------------------------------------

   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 ---------------------------------------------------------

   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 ------------------------------------------------------------

   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 ------------------------------------------------------------

   OTP-11016  Postscript files no longer needed for the generation of PDF
	      files have been removed.

--- cosFileTransfer -----------------------------------------------------

   OTP-11016  Postscript files no longer needed for the generation of PDF
	      files have been removed.

--- cosNotification -----------------------------------------------------

   OTP-11016  Postscript files no longer needed for the generation of PDF
	      files have been removed.

--- crypto --------------------------------------------------------------

   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

	      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 ------------------------------------------------------------

   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 ------------------------------------------------------------

   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.

	      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 ------------------------------------------------------------

    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.<br/> 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.

--- erts ----------------------------------------------------------------

   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. For more information
	      see the documentation of the +M<S>acul command line argument.

	      When enabling this feature 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.

	      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
	      Vinovski.

   OTP-11074  Optimization of simultaneous inet_db operations on the same
	      socket by using a lock free implementation.

   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 algorithm for management of the process, and port
	      tables has been introduced. 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 this 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-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.

   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 Lo?c 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
	      term_to_binary is used. 

	      Impact: Programs running term_to_binary on large terms will
	      run more smothly, but rescheduling will impact the single
	      process performance of the BIF. Single threaded benchmarks
	      will show degraded performance of the BIF when called with
	      very large terms, while general system behaviour will be
	      improved. The overhead for allowing restart and reduction
	      counting also degrades local performance of the BIF with
	      between 5% and 10% even for small terms.

   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.

	      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-10991  A bug in test_server_gl caused io requests containing invalid
	      data (i.e. not unicode:chardata()) to hang, since no io reply
	      was sent. This has been corrected.

   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.

	      In particular, search using the source path in module_info if
	      the current heuristic fails.

   OTP-10930  Remove Flymake dependency in erlang-pkg.el. Thanks to Magnus
	      Henoch.

   OTP-10979  When cover:stop(Node) was called on a non-existing node, a
	      process waiting for cover data from the node would hang
	      forever. This has been corrected.

   OTP-10999  Erlang-mode: Add autoload cookies for file extension
	      associations. Thanks to Magnus Henoch.

   OTP-11016  Postscript files no longer needed for the generation of PDF
	      files have been removed.
