- Changes for 27.1:
  * crypto: crypto built with --enable-fips will now accept an
    OpenSSL 3 lib without fips provider as long as fips mode is not
    enabled.
  * crypto: Added a warning in the documentation to avoid calling
    crypto:start/0 as it does not work for FIPS mode. Use
    application:start(crypto) instead.
  * crypto: Deprecation of RSA encryption functions has been
    reverted, as there still exists legitimate use cases with other
    padding modes than PKCS-1.
  * crypto: Compiler warnings for some removed functions have been
    corrected to point out the correct replacement functions.
  * ssh: The SSh daemon started with a TCP port number argument
    will now re-try obtaining a listen socket before returning an
    error to the user.
  * ssh: Robustness has been improved by monitoring the connection
    handler process before casting the socket control notification.
  * ssl: A race in the kTLS flavour of SSL distribution has been
    fixed so that inet_drv.c doesn't read ahead too much data,
    which could cause the kTLS encryption to be activated too late
    when some encrypted data had already been read into the
    inet_drv.c buffer as unencrypted.
  * ssl: All TLS-1.3 terminations are now graceful (previous TLS
    version terminations already were).
  * ssl: It is now possible to use a verification fun of arity 4,
    giving the user fun access to both encoded and decoded versions
    of the certificate. This is desirable as a workaround for
    encoding errors preventing re-encoding from being reliable.
    This also saves some work load if the encoded version is
    needed.
  * ssl: Compiler warnings for some removed functions have been
    corrected to point out the correct replacement functions.
  * ssl: Include more information in logging of SNI (Server Name
    Indication) mismatch error.
  * diameter: Function specs for the main API module has been
    updated.
  * diameter: Man pages are now available for erl, erlc, dialyzer,
    and all other programs that are included in Erlang/OTP.
  * diameter: diameter:stop_service/1 has been made more
    synchronous.
  * wx: Documentation has been improved.
  * public_key: For completeness handle rsa_pss implicit default
    value, although this will probably not be commonly used as it
    provides very weak security.
  * public_key: The public_key:cacerts_load() function could in
    some error cases return undefined instead of {error, Reason}.
  * public_key: Added support for DragonFly.
  * public_key: Deprecation of RSA encryption functions has been
    reverted, as there still exists legitimate use cases with other
    padding modes than PKCS-1.
  * public_key: It is now possible to use a verification fun of
    arity 4, giving the user fun access to both encoded and decoded
    versions of the certificate. This is desirable as a workaround
    for encoding errors preventing re-encoding from being reliable.
    This also saves some work load if the encoded version is
    needed.
  * snmp: Man pages are now available for erl, erlc, dialyzer, and
    all other programs that are included in Erlang/OTP.
  * snmp: Figures in the documentation have been improved.
  * tftp: The legacy dependency to m:error_logger has been removed.
    m:logger is now used.
  * ftp: Eliminated a race condition that sometimes resulted in
    ftp:recv_bin/2 returning ok instead of {ok, Data}.
  * odbc: Figures in the documentation have been improved.
  * compiler: Fixed a crash in an optimization pass relating to
    appending binaries.
  * compiler: Fixed a bug in the compiler's alias analysis pass
    that could make it emit unsafe code.
  * common_test: Groups with empty list specifying groups and test
    cases no longer crash execution.
  * common_test: The Common_Test documentation and type specs have
    been polished.
  * common_test: Man pages are now available for erl, erlc,
    dialyzer, and all other programs that are included in
    Erlang/OTP.
  * dialyzer: Man pages are now available for erl, erlc, dialyzer,
    and all other programs that are included in Erlang/OTP.
  * xmerl: Corrected export functions from internal structure to
    XML so xmlText items of type cdata are handled correctly. They
    were just exported as normal text instead of output in a CDATA
    section.
  * xmerl: The type spec for xmerl_sax_parser:file/2 has been
    corrected to indicate that it can return an {error, _} tuple.
  * runtime_tools: Fixed a bug where dbg sessions on remote nodes
    were terminated prematurely.
  * inets: The documentation for the m:httpd module has been
    improved, along with correction of headings and types.
  * inets: Userinfo is now properly percent-decoded before usage in
    headers.
  * stdlib: The help printout for incorrect t:io:format/0 strings
    now handles the k modifier correctly.
  * stdlib: Fixed a bug that caused the shell completion to crash
    when keyword and tuple appeared on the same line.
  * stdlib: Due to PR-7419/OTP-18671, the cached internal value of
    the callback_mode started leaking out to logger reports, which
    could cause logger handlers to crash.  This has now been fixed
    to show the value that was set, as before caching.
  * stdlib: Fixed an emulator crash relating to compressed ETS
    tables.
  * stdlib: The error description for maps:update/3 will no longer
    insist that the third argument is not a map when a key could
    not be found
  * stdlib: Multiple issues have been corrected in the markdown
    parser that creates documentation for the shell.
  * stdlib: Fixed category for some codepoint ranges in
    unicode_util.
  * stdlib: Fixed m:argparse to print sub-commands help when
    available.
  * stdlib: Class annotation to HTML from fenced blocks have been
    added.
  * stdlib: Added JSON formatting functions for indented output.
  * stdlib: Improved illegal pattern error for accidental map
    associations.
  * stdlib: Progress reports for a dynamically started supervisor
    will now be logged at debug level.
  * stdlib: The m:zip module has been updated with support for:
  * edoc: Broken links in release notes have been mended.
  * tools: m:tprof no longer crashes when using
    pause/restart/continue when profiling all modules.
  * tools: On systems supporting native coverage, calls to m:cover
    could hang or crash if cover-compiled module had been reloaded
    from outside cover. This has been corrected so that cover now
    recovers from the error and and sends a report to the logger
    about the failure to retrieve coverage information.
  * tools: Figures in the documentation have been improved.
  * erts: The erl -man example has been corrected to not consider
    values set in ERL_ZFLAGS and stop parsing arguments when a --
    is encountered.
  * erts: Compiler warnings for  Windows I/O back-end have been
    silenced.
  * erts: Bugs related to return_to trace have been fixed. It did
    not work for more than once trace session and it did sometimes
    not trigger for exceptions.
  * erts: Potential deadlocks while writing a crash dump have been
    eliminated.
  * erts: When loading a damaged or too old BEAM file, the runtime
    system could crash.
  * erts: A scheduler thread could get stuck when deleting a memory
    allocator carrier when adjacent carriers were deleted and/or
    inserted simultaneously by other schedulers. This in turn could
    cause the other schedulers to get stuck as well.
  * erts: Statistics for number of carriers in a shared pool after
    calling instrument:allocations or instrument:carriers are now
    correct. Also, a potential bug in carrier block scanning was
    eliminated.
  * erts: A race in the kTLS flavour of SSL distribution has been
    fixed so that inet_drv.c doesn't read ahead too much data,
    which could cause the kTLS encryption to be activated too late
    when some encrypted data had already been read into the
    inet_drv.c buffer as unencrypted.
  * erts: Fixed an emulator crash relating to compressed ETS
    tables.
  * erts: A function (encode_sockaddr) was called with superfluous
    argument, on Windows, in the net nif.
  * erts: Fixed a crash that could happen on reallocation failure.
  * erts: Man pages are now available for erl, erlc, dialyzer, and
    all other programs that are included in Erlang/OTP.
  * erts: A previous correction in the Erlang/OTP 27.0.1 emergency
    patch had the unfortunate side effect of sometimes causing an
    unnecessary fullsweep (major) garbage collection instead of a
    generation (minor) garbage collection. This has been corrected.
  * erts: Fixed trace matchspec functions trace and enable_trace to
    use the session tracer when enabling trace flags on untraced
    processes.
  * erts: Fixed a typo in the type spec for
    t:erlang:garbage_collection_defaults/0.
  * erts: Corrected socket:ioctl for genaddr (SIOCGENADDR).
  * erts: The support for Transparent Huge Pages has been disabled
    on non-amd64 Linux systems.
  * erts: Fixed a race condition on Windows when upgrading from
    -noshell to a shell that would cause Erlang to crash with the
    error:
  * erts: Added functions getservbyname and getservbyport to the
    net module.
  * erts: Introduced enet | esock variants of m:inet functions,
    either when called with sockets, with explicit inet_backend
    config or with the e inet_backend kernel config option.
  * erts: Optimize process and port creation when such tracing is
    not enabled by any trace session.
  * erts: Compiler warnings for some removed functions have been
    corrected to point out the correct replacement functions.
  * erts: A boolean option read_ahead has been implemented for
    gen_tcp, default true, to facilitate not reading past (caching
    data) the end of a packet.  In particular, for kTLS, caching
    data could read in data that was supposed to be decrypted by
    the platform's network stack, before crypto parameters could be
    activated.
  * erts: The m:zip module has been updated with support for:
  * kernel: A faulty assertion was corrected in the prim_tty
    module. This assertion could trigger when invalid UTF-8 was
    read from stdin just as the mode was changed from unicode to
    latin1.
  * kernel: Opening a disk_log file and combining head_func with
    rotate options did not work.
  * kernel: Fixed an error info printout for
    erlang:is_process_alive/1 on non-local pids.
  * kernel: A race in the kTLS flavour of SSL distribution has been
    fixed so that inet_drv.c doesn't read ahead too much data,
    which could cause the kTLS encryption to be activated too late
    when some encrypted data had already been read into the
    inet_drv.c buffer as unencrypted.
  * kernel: Fixed a deadlock when an application crashes during
    startup and log messages were sent to standard out. Logger
    would fail to print the messages to standard out and instead
    print them to standard error.
  * kernel: The -proto_dist init parameter will no longer be
    ignored when specified multiple times. It will now log a
    warning and use the first specified value.
  * kernel: Corrected socket:ioctl for genaddr (SIOCGENADDR).
  * kernel: Added functions getservbyname and getservbyport to the
    net module.
  * kernel: Introduced enet | esock variants of m:inet functions,
    either when called with sockets, with explicit inet_backend
    config or with the e inet_backend kernel config option.
  * kernel: The function socket:i/0 now uses the m:net module
    (instead of the m:inet module) for service translation.
  * kernel: A boolean option read_ahead has been implemented for
    gen_tcp, default true, to facilitate not reading past (caching
    data) the end of a packet.  In particular, for kTLS, caching
    data could read in data that was supposed to be decrypted by
    the platform's network stack, before crypto parameters could be
    activated.
  * syntax_tools: The documentation for syntax_tools has been
    polished after the migration to the new documentation system.
  * asn1: Fixed a cosmetic but harmless issue with the ASN.1
    compiler passing on the undec_rest option to the Erlang
    compiler.
- Changes for 27.0.1:
  * ssh: With this change, race condition between connection
    closing and automatic window adjustment is fixed.
  * ssl: Check  for TLS-1.3 support should check minimum
    requirements.
  * ssl: If both TLS-1.3 and TLS-1.2 is supported and TLS-1.2
    negotiated convert TLS-1.3 ECDSA schemes to TLS-1.2 hash and
    signature pairs for increased interoperability.
  * ssl: TLS-1.3 negotiation now uses SNI based options correctly
    instead of ignoring them.
  * ssl: Make it easier to distinguish between a invalid signature
    and unsupported signature.
  * ssl: Enhance ALERT logs to help understand what causes the
    alert.
  * ssl: When the default value for signature_algs is used, default
    the signature_algs_cert to the default value + rsa_pkcs1_sha1
    to allow this algorithms for certificates but not for the TLS
    protocol. This is for better interoperability.  If
    signature_algs is set explicitly signature_algs_cert must also
    be set explicitly if they should be different.
  * public_key: Fix bug in dnsName constraint check, could cause
    valid cert to be considered bad during path validation.
  * compiler: One of the compiler's optimization passes would get
    very slow when compiling certain modules. The compiler will now
    automatically disable that pass for input that would trigger
    the slowdown.
  * compiler: Fix +deterministic to work properly with
    documentation attributes.
  * stdlib: Fix so that missing -doc({file, File}) files only
    result in a warning and not an error.
  * stdlib: Fixed m:json bugs, json:encode_key_value_list/2 did not
    generate arrays and json:decode/3 did not invoke the user
    callback for 0.
  * edoc: Fix broken makefile dependency when building HTML
    documentation.
  * erts: In rare circumstances the JIT could do an unsafe in-place
    update of a tuple.
  * erts: When a port command crashed in the inet driver during
    gen_tcp:send/2, a monitor 'DOWN' message could be left
    lingering in the caller's mailbox. This has now been fixed.
  * erts: 'DOWN' messages originating from a monitored port,
    contained the atom process instead of the atom port as the
    third element when the exit reason was not an immediate term.
  * erts: Fix so that the options to enable Transparent Huge Page
    alignment of the Erlang VM executable are only applied to the
    Erlang VM and not other native programs such as erlc and
    dialyzer. This bug was introduced in Erlang/OTP 27.0.
  * erts: When [*no time warp mode*](time_correction.md#no-time-
    warp-mode) was enabled, a smaller Erlang monotonic time could
    be read than a previously read time, i.e., breaking the
    monotonic property. The runtime system will abort when
    detecting an issue like this since OTP 24.3.4.17 and OTP 25.0.
  * erts: When calling trace:function(Session, _, true, [meta]) the
    meta tracer was incorrectly set to be the calling process. Now
    it's set to the session tracer as expected.
  * kernel: Polish the m:logger documentation.
- Version 27.0:
  * Triple-Quoted Strings has been implemented as per EEP 64 to
    allow a string to encompass a complete paragraph.
  * Adjacent string literals without intervening white space is now
    a syntax error, to avoid possible confusion with triple-quoted
    strings.
  * Sigils on string literals (both ordinary and triple-quoted)
    have been implemented as per EEP 66. For example, ~"Björn" or
    ~b"Björn" are now equivalent to <<"Björn"/utf8>>.
  * The compiler will now merge consecutive updates of the same
    record.
  * Safe destructive update of tuples has been implemented in the
    compiler and runtime system. This allows the VM to update
    tuples in-place when it is safe to do so, thus improving
    performance by doing less copying but also by producing less
    garbage.
  * The maybe expression is now enabled by default, eliminating the
    need for enabling the maybe_expr feature.
  * Native coverage support has been implemented in the JIT. It
    will automatically be used by the cover tool to reduce the
    execution overhead when running cover-compiled code. There are
    also new APIs to support native coverage without using the
    cover tool.
  * The compiler will now raise a warning when updating record/map
    literals to catch a common mistake. For example, the compiler
    will now emit a warning for #r{a=1}#r{b=2}.
  * The erl command now supports the -S flag, which is similar to
    the -run flag, but with some of the rough edges filed off.
  * By default, escripts will now be compiled instead of
    interpreted. That means that the compiler application must be
    installed.
  * The default process limit has been raised to 1048576 processes.
  * The erlang:system_monitor/2 functionality is now able to
    monitor long message queues in the system.
  * The obsolete and undocumented support for opening a port to an
    external resource by passing an atom (or a string) as first
    argument to open_port(), implemented by the vanilla driver, has
    been removed. This feature has been scheduled for removal in
    OTP 27 since the release of OTP 26.
  * The pid field has been removed from erlang:fun_info/1,2.
    Multiple trace sessions are now supported.
  * There is a new module json for encoding and decoding JSON.
  * Several new functions that accept funs have been added to module timer.
  * The functions is_equal/2, map/2, and filtermap/2 have been
    added to the modules sets, ordsets, and gb_sets.
  * There are new efficient ets traversal functions with guaranteed
    atomicity. For example, ets:next/2 followed by ets:lookup/2 can
    now be replaced with ets:next_lookup/1.
  * The new function ets:update_element/4 is similar to
    ets:update_element/3, but takes a default tuple as the fourth
    argument, which will be inserted if no previous record with
    that key exists.
  * binary:replace/3,4 now supports using a fun for supplying the
    replacement binary.
  * The new function proc_lib:set_label/1 can be used to add a
    descriptive term to any process that does not have a registered
    name. The name will be shown by tools such as c:i/0 and
    observer, and it will be included in crash reports produced by
    processes using gen_server, gen_statem, gen_event, and gen_fsm.
  * Added functions to retrieve the next higher or lower
    key/element from gb_trees and gb_sets, as well as returning
    iterators that start at given keys/elements.
  * common_test: Calls to ct:capture_start/0 and ct:capture_stop/0
    are now synchronous to ensure that all output is captured.
  * common_test: The default CSS will now include a basic dark mode
    handling if it is preferred by the browser.
  * crypto: The functions crypto_dyn_iv_init/3 and
    crypto_dyn_iv_update/3 that were marked as deprecated in
    Erlang/OTP 25 have been removed.
  * dialyzer: The --gui option for Dialyzer has been removed.
  * ssl: The ssl client can negotiate and handle certificate status
    request (OCSP stapling support on the client side).
  * tools: There is a new tool tprof, which combines the
    functionality of eprof and cprof under one interface. It also
    adds heap profiling.
  * xmerl: As an alternative to xmerl_xml, a new export module
    xmerl_xml_indent that provides out-of-the box indented output
    has been added.

- Changes for 26.2.5.2:
  * erts: When no time warp mode was enabled, a smaller Erlang
    monotonic time could be read than a previously read time, i.e.,
    breaking the monotonic property. The runtime system will abort
    when detecting an issue like this since OTP 24.3.4.17 and OTP
    25.0. Up until OTP 25 no time warp mode is the default. As of
    OTP 26 multi time warp mode is the default.
  * erts: A scheduler thread could get stuck when deleting a memory
    allocator carrier when adjacent carriers were deleted and/or
    inserted simultaneously by other schedulers. This in turn could
    cause the other schedulers to get stuck as well.
  * crypto: Add warning in documentation to avoid crypto:start/0 as
    it does not work for FIPS mode. Use application:start(crypto)
    instead.
  * stdlib: Fixed a bug that caused the shell completion to crash
    when keyword and tuple appeared on the same line.
  * ssl: When the default value for signature_algs is used, default
    the signature_algs_cert to the default value + rsa_pkcs1_sha1
    to allow this algorithms for certificates but not for the TLS
    protocol. This is for better interoperability. If
    signature_algs is set explicitly signature_algs_cert must also
    be set explicitly if they should be different.
- Changes for 26.2.5.1:
  * erts: A call to socket:[recv|recvfrom|recvmsg]/* with Timeout =
    0 on Windows could cause a (case clause) crash if data is
    immediately available.
  * erts: When a port command crashed in the inet driver during
    gen_tcp:send/2, a monitor 'DOWN' message could be left
    lingering in the caller's mailbox. This has now been fixed.
  * erts: 'DOWN' messages originating from a monitored port,

- Changes for 26.2.4
  * asn1: An ASN.1 module that contains named BIT STRING values
              would fail to compiled if both the BER and JER
              back-ends were enabled.
  * Compiler: In rare circumstances, the compiler code generate
              unsafe code for a bit syntax match.
  * Compiler: In rare circumstances, binary matches that were
              supposed to succeed failed.
  * Compiler: Fixed a bug where a fun's environment could be
              overridden by an argument in some cases.
  * Crypto: Fix building with --enable-fips with OpenSSL 3 on
              MacOS.
  * Debugger: Guards with nested record expression could wrongly
              evaluate to false.
  * Diameter: Reduce the impact of calling service_info by not
              counting the binaries (on the heap) info, This is done
              by introducing an option, bins_info, which controls
              this.
  * erts: Fixed CPU quota determination for cgroup version 2
  * erts: Fix faulty reduction counting in exiting process which
               could cause it to do unnecessary yielding.
  * erts: Fix bug in re:run/3 where if an invalid UTF-8 subject
               was given, re:run could get stuck in an infinite loop.
               Bug was introduced in Erlang/OTP 22.1.
  * erts: On AArch64 (ARM64), Erlang code using bit syntax
               construction compiled using Erlang/OTP 24 could crash
               the runtime system when run in Erlang/OTP 26.2.3.
  * erts: Calling erlang:trace/3 with first argument one of
               ports, processes, existing_ports, existing_processes,
               existing or all, could cause emulator crash if a dirty
               scheduler was executing a simultaneous trace action.
  * erts: Fixed an integer overflow when the monotonic time unit
               reported by the operating system was greater than 10
               and lower than 100 microseconds.
  * erts: Fix option reuseaddr for FreeBSD 14
  * erts: When a traced process executing on a dirty scheduler
               received an exit signal, the dirty scheduler could use
               the wrong thread specific data which could lead to a
               crash.
  * erts: Fixed a more or less harmless bug that caused time
               correction of Erlang monotonic time to become slightly
               off on Windows platforms when QueryPerformanceCounter()
               was used as OS monotonic time source.
               erlang:system_info(os_monotonic_time_source) now also
               returns information about used resolution which not
               always corresponds to the resolution of the OS
               monotonic time source.
  * erts: When using IPv6, classic gen_udp failed to add (group)
               membership (drop was used instead).
  * erts: Fix bug on Windows where "Unknown event: 2" would be
               printed to the console.
  * erts: Checks for monotonicity of monotonic time have been
               improved so that Erlang and OS monotonic time are
               checked separately.
  * erts: For severe errors, when the `socket` module terminates
               the Erlang VM, now an erl_crash.dump is produced, to
               facilitate post mortem debugging.
  * kernel: When using IPv6, classic gen_udp failed to add (group)
               membership (drop was used instead).
  * kernel: The check in inet_res of the RD bit has been relaxed
               slightly.
  * ssh: With this change, owner and group file attributes
               decoding is fixed and results with value of integer
               type.
  * ssl: Cleanup and close all connections in DTLS when the
               listen socket owner dies.
               Improved IPv6 handling in DTLS.
  * ssl: Fixed a crash in dtls accept.
  * stdlib: Attempting to use the maybe construct in a macro
               argument could crash the compiler.
- Changes for 26.2.3
  * otp: Quote uninstall path in registry when installing on
               windows.
  * compiler: In rare circumstances, an unsafe optimization could
               cause the compiler to generate incorrect code for list
               matching.
  * compiler: Fix the compilation server to restart if the
               applications in its lib dir changes inbetween erlc
               invokations.
  * crypto: Fix compile error when OPENSSL_NO_DES is defined.
  * crypto: The function crypto:pbkdf2_hmac will no longer block
               the main schedulers. If the iteration count or block
               size parameters are such that the function is likely to
               take a long time to execute, the function will be
               scheduled to run on a dirty CPU scheduler.
  * erts: Fixed compile warning in erl_nif.c for gcc-13.
  * erts: Fix C++ compile error for macros enif_select_read and
               friends.
  * erts: Fixed a name clash on Solaris that prevented the JIT
               from being built.
  * erts: Fix termcap detection on solaris.
  * erts: Fix heap corruption bug that could cause runaway memory
               consumption due to circular offheap list at process
               exit. Other symptoms may also be possible. Bug exists
               since OTP 25.0.
  * erts: Do not clear tracing in old module instance if load
               fails with 'not_purged'.
  * erts: When exceeding the `max_heap_size` limit in a garbage
               collection initiated by some bit syntax operations, the
               process would not always terminate immediately.
  * erts: The code server could be hanging if a module with
               on_load function was loaded at the same time as another
               module was purged using erlang:purge_module directly.
  * erts: A process optimized for parallel signal delivery could
               under some circumstances lose wakeup information. That
               is, the processes was not woken up to take care of the
               signal, so the signal would not be taken care of until
               the process was woken by another signal. Only processes
               configured with message_queue_data set to off_heap
               utilize this optimization.
  * erts: Fix segfault when generating crashdump containing a fun
               places in persistent_term storage.
  * erts: By default the JIT is disabled on Intel Macs, because
               of annoying poups on macOS Sonoma. It is now possible
               to explicitly enable the JIT on Intel Macs. Here is
               how: ./configure --enable-jit
  * kernel: Fix performance bug when using io:fread to read from
               standard_io. This regression was introduced in OTP
               26.0.
  * kernel: A bug in the code server could cause it to crash in
               some concurrent scenarios. This bug was introduced in
               26.1.
  * kernel: Fixed gen_udp:open/2 type spec to include already
               supported module socket address types.
  * kernel: Fix reading of password for ssh client when in
               user_interactive mode.
  * odbc: Use spec for API doc
  * public_key: Hostname prefix with X number of dots should not be
               accepted.
  * ssh: With this change, acceptor_sup is not started for ssh
               client as it is not needed in that role.
  * ssh: With this change, more secure algorithms are preferred
               by ssh and documentation is updated to reflect that.
  * ssh: With this change, KEX strict terminal message is
               emitted with debug verbosity.
  * ssh: Fix reading of password for ssh client when in
               user_interactive mode.
  * ssl: ssl:prf/5, will start working instead of hanging in a
               TLS-1.3 context if called appropriately. Note that the
               implementation has changed and in OTP-27 a more
               adequate API will be documented.
  * ssl: Server name verification didn't work if a connection
               was made with IP-address as a string.
  * ssl: The fallback after "dh" ssl option was undefined was to
               get "dh" from ssl options again. This is clearly wrong
               and now changed to the documented fallback "dhfile" ssl
               option.
  * ssl: Correct default value selection for DTLS. Will only
               affect users linked with really old version of
               cryptolib library.
  * ssl: Adhere elliptic curves with RFC 8422 pre TLS-1.3, that
               is Edwards curves are added to curves that can be used
               for key exchange, and documentation and implementation
               of eccs/0,1 are aligned.
  * ssl: Improve alert reason when ecdhe_rsa key_exchange does
               not have any common curves to use
  * stdlib: The help texts shown by argparse will now display
               sub-command arguments in the correct order.
  * stdlib: Clarified the argparse documentation regarding the
               user-defined help template.
  * stdlib: Fix shell expansion to not crash when expanding invalid
               using invalid atoms.
  * wx: Add option to silence wx depracation macros.
- Changes for 26.2.2
  * common_test: Fix how CT finds Erlang/OTP releases for compatability
               testing. This functionality is only used to test
               Erlang/OTP.
  * erl_interface: Fix bug where the system installed openssl/md5.h would
               be confused with the vendored md5.h.
  * erts: 32-bit runtime systems on most Unix like platforms
               could crash if a BIF timer was set with a huge timeout
               of more than 68 years into the future. In order for the
               crash to occur, the huge timer (at a later time than
               when it was set) had to become the nearest active timer
               set on the specific scheduler on which it was set. This
               could not happen on a system with only one scheduler
               since there would always be shorter timers in the
               system.
               Setting a timer larger than 49 days on Windows could
               under rare circumstances cause the timeout to be
               delayed.
  * erts: Fix bug where the system installed openssl/md5.h would
               be confused with the vendored md5.h.
  * erts: The JIT has now been disabled on x86 Macs to prevent
               annoying the "verifying shm-xyz" popups introduced in
               MacOS Sonoma.
               ARM Macs are unaffected.
  * erts: Garbage collection of a process on a dirty scheduler
               could collide with signal handling for that process
               causing a crash of the runtime system. This bug was
               introduced in OTP 25.3.2.8 and OTP 26.2.
  * kernel: Fix group (that is the shell) to properly handle when
               an get_until callback function returned {done, eof, []}
               when an eof was detected.
  * ssh: With this change, Curve25519 and Curve448 KEX methods
               become most preferred (related to RFC8731).
  * ssl: Legacy name handling could cause interop problems
               between TLS-1.3/1.2 client and TLS-1.2 server.

  * erts: Removed unnecessary PCRE source tar-ball.
  * ssh: With this change (being response to CVE-2023-48795),
    ssh can negotiate "strict KEX" OpenSSH extension with
    peers supporting it; also
    'chacha20-poly1305@openssh.com' algorithm becomes a
    less preferred cipher.
    If strict KEX availability cannot be ensured on both
    connection sides, affected encryption modes(CHACHA and
    CBC) can be disabled with standard ssh configuration.
    This will provide protection against vulnerability, but
    at a cost of affecting interoperability. See

    planned for OTP 27, has been postponed to OTP 29.
  * asn1: Fix benign warning from gcc 11 about mismatching call
    to free().
  * crypto: Enable engine support for OpenSSL versions 3.

- Changes for 26.1.2:
  * erts: If the external term format encoding of an argument list
    part of a distributed spawn operation was faulty, the newly
    spawned remote process could misbehave. The misbehavior
    included hanging or interpret an incoming message as an
    argument list to use. This was very unlikely to happen unless
    using an alternate implementation of the distribution protocol
    which made a faulty encoding of the argument list. The child
    process will now detect this error and terminate before
    executing the user specified code.
  * erts: Fix bugs where if the body of a matchspec would return a
    map with a variable ('$1', '$_' etc) as one of the keys or
    values and the variable was not an immidiate, the term would
    not be copied to the receiving processes heap. This would later
    corrupt the term in the table as the GC could place move
    markers in it, which in turn would cause the VM to crash. Bug
    has been present for since OTP 17.0.
  * xmerl: The xmerl version 1.3.32 was released in OTP 26.0.1, but
    the incorrect version number of 1.3.31.1 was used for it. This
    incorrect version number continued to appear in OTP 26.0.2, OTP
    26.1, and OTP 26.1.1. The actual xmerl code in these OTP
    versions however corresponds to xmerl version 1.3.32.
- Changes for 26.1.1:
  * wx: The wx application would fail to build on macOS with Xcode
    15.
  * compiler: The compiler could become extremely slow for modules
    containing huge functions.
  * stdlib: Garbage collect the shell process when reducing the
    amount of saved history and results.

  * compiler: The compiler could be very slow when compiling guards
    with multiple guard tests separated with 'or' or ';'.
- Changes for 25.3.2.1:
  * xmerl: New options to xmerl_scan and xmerl_sax_parser so one
    can limit the behaviour of the parsers to avoid some XML
    security issues. xmerl_scan gets one new option:
    xmerl_sax_parser gets the following options: The old option
    skip_external_dtd is still valid and the same as
    {external_entities, none} and {fail_undeclared_ref, false} but
    just affects DTD's and not other external references.
  * erts: Fixed a crash during tracing on certain platforms that
    cannot use the machine stack for Erlang code (mainly OpenBSD
    and Linux with musl).
  * erts: Constructing a binary segment not aligned with a byte
    boundary, with a size not fitting in 31 bits, and with a value
    not fitting in a 64-bit word could crash the runtime system.
  * erts: Further robustify implementation of large maps (> 32
    keys). Keys that happen to have same internal 32-bit hash
    values are now put in collision nodes which are traversed with
    linear search. This removes the demand for the internal hash
    function when salted to eventually produce different hashes for
    all possible pairs of unequal terms.
  * stdlib: Static supervisors are very idle processes after they
    have started so they will now be hibernated after start to
    improve resource management.
  * compiler: Fixed a bug where a failing bsl expression in a guard
    threw an exception instead of causing the guard to fail.

    guard BIFs that can fail could sometimes be miscompiled so that

- Changes for 25.3.2:
  * compiler: Fixed type handling bugs that could cause an internal
    error in the compiler for correct code.
  * os_mon: Avoid error report from failing erlang:port_close at
    shutdown of cpu_sup and memsup. Bug exists since OTP 25.3
    (os_mon-2.8.1).
  * erts: If a runtime system which was starting the distribution
    already had existing pids, ports, or references referring to a
    node with the same nodename/creation pair that the runtime
    system was about to use, these already existing pids, ports, or
    references would not work as expected in various situations
    after the node had gone alive. This could only occur if the
    runtime system was communicated such pids, ports, or references
    prior to the distribution was started. That is, it was
    extremely unlikely to happen unless the distribution was
    started dynamically and was even then very unlikely to happen.
    The runtime system now checks for already existing pids, ports,
    and references with the same nodename/creation pair that it is
    about to use. If such are found another creation will be chosen
    in order to avoid these issues.
- Changes for 25.3.1:
  * snmp: Attempts to minimize the number of the error reports
    during a failed agent init.
  * compiler: When a map update such as #{}#{key:=value} that
    should fail with an exception was unused, the exception would
    be lost.
  * compiler: Fixed bug in the validator that made it reject valid
    code.
  * crypto: With this change, random errors are fixed for
    crypto:generate_key calls with OpenSSL 3.

  * reltool: Fixed a bug that would cause analysis to crash.
  * stdlib: Fixed a bug that would cause analysis to crash.
  * stdlib: Fixed a crash when formatting stack traces for error
    reports.
  * stdlib: Instead of crashing, the list_to_integer/1 and
    list_to_integer/2 BIFs now raise the system_limit exception for
    overlong lists that can't be converted to integers. Similarly,
    the string:to_integer/1 BIF now returns {error,system_limit}
    for overlong lists.
  * stdlib: Removal of non-necessary undefined types added to the
    state's supervisor record.
  * compiler: Fixed a bug that would cause the compiler to hang.
  * compiler: Fixed a crash when compiling code that contained
    maybe expressions.
  * compiler: Constructing a binary with an explicit size of all
    for a binary segment would crash the compiler.
  * compiler: The compiler would generate incorrect code for the
    following type of expression: Pattern = BoundVar1 = . . . =
    BoundVarN = Expression An exception should be raised if any of
    the bound variables have different values than Expression. The
    compiler would generate code that would cause the bound
    variables to be bound to the value of Expressionwhether the
    value matched or not.
  * xmerl: Replace size/1 with either tuple_size/1 or byte_size/1
    The size/1 BIF is not optimized by the JIT, and its use can
    result in worse types for Dialyzer. When one knows that the
    value being tested must be a tuple, tuple_size/1 should always
    be preferred. When one knows that the value being tested must
    be a binary, byte_size/1 should be preferred. However,

  * erts: Fixed minor memory leaks.
  * erts: Fix bugs in ets:insert and ets:insert_new when called
    with a list of tuples to insert while a concurrent process
    either deletes or renames the table. The table deletion could
    be done with ets:delete/1 or be caused by termination of the
    table owning process. Symptoms are either VM crash or strange
    incorrect behavior from the insert operation. The risk of
    triggering the bugs increases with the length of the list of
    tuple to insert. Bugs exist since OTP 23.0.
  * erts: Boost execution of scheduled thread progress jobs. This
    to prevent memory exhaustion in extremely rapid
    allocation/deallocation scenarios, such as repeated ETS table
    creations/deletions.

  * ssl: Fixes handling of symlinks in cacertfile option.
  * eunit: With this change, eunit exact_execution option works

  * stdlib: peer nodes failed to halt when the process supervising
    the control connection crashed. When an alternative control
    connection was used, this supervision process also quite
    frequently crashed when the peer node was stopped by the node

  * asn1: For the per and uper ASN.1 encoding rules, encoding and
    decoding the SEQUENCE OF and SET OF constructs with 16384 items
    or more is now supported.
  * erts: Listen sockets created with the socket module, leaked

  * erts: Distributed exit signals could be lost under the
    following conditions:
  * erts: A race could cause process_info(Pid, message_queue_len)
    on other processes to return invalid results.
  * erts: Fixed reduction counting for handling process system
    tasks.
  * erts: Priority elevation of terminating processes did not work
    which could cause execution of such processes to be delayed.
  * erts: An unlink operation made by a process that terminated
    before the unlink operation completed, i.e., before it had
    received an unlink-ack signal from the linked process, caused
    an exit signal to erroneously be sent from the terminating
    process to the process being unlinked. This exit signal would
    most often be ignored by the receiver, but if the receiver of
    the exit signal concurrently set up a new link, it could
    receive the exit signal with the actual exit reason of the
    terminating process instead of a noproc exit reason. It is
    however very hard to detect that this has happened and has no
    obvious negative consequences, so it should be considered
    harmless. A distributed unlink-ack signal received by a
    terminating process was also not properly removed which could
    cause a minor memory leak.
  * ssl: The link to crypto:engine_load refered the function with
    wrong arity.

  * erts: On computers with the ARM64 (AArch64) architecture (such
    as Apple Silicon Macs) a rem expression followed by a div
    expression with the same operands could evaluate to the wrong
    result if the result of the rem expression was unused.
- Changes for 25.0.1:
  * ssl: When a TLS-1.3 enabled client tried to talk to a TLS-1.2
    server that coalesces TLS-1.2 handshake message over one TLS
    record, the connection could fail due to some message being
    handled in the wrong state, this has been fixed.
  * ssl: Correctly handles supported protocol version change from
    default to something else by sni_fun supplied to
    ssl:handshake/[2,3] together with a TCP-socket (so called
    upgrade).
  * ssl: Also, TLS-1.3 should respond with a protocol version alert

    certificate request message.
- Changes for 24.3:
  * megaco: The compilation time is no longer recorded in BEAM
    files. There remained several undocumented functions that
    attempted to retrieve compilation times. Those have now been
    removed.
  * megaco: Update the performance and debug chapters of the megaco
    user's guide. Also some updates to the meas tools.
  * compiler: The expression <<0/native-float>>=Bin would always
    fail to match, while <<0/float-native>>=Bin would match
    (provided that Bin contained the binary representation of 0.0)
  * compiler: The compiler will now compile huge functions with
    straight-line code faster.
  * erl_interface: Add --enable-ei-dynamic-lib configure option

Matwey Kornilov (matwey) accepted request 956544 from Matwey Kornilov (matwey) over 2 years ago (revision 119)

- Changes for 24.2.1:
  * ssl: Improve SNI (server name indication) handling so that
    protocol version can be selected with regards to SNI. Also,
    make sure that ssl:connection_information/1 returns the correct
    SNI value.
  * ssl: Fixed cipher suite listing functions so that the listing
    of all cipher suites will be complete. Another fix for cipher
    suite handling in OTP-24.1 accidentally excludes a few cipher
    suites from the listing of all cipher suites.
  * ssl: Reenable legacy cipher suite TLS_RSA_WITH_3DES_EDE_CBC_SHA
    for explicit configuration in TLS-1.2, not supported by
    default.
  * ssl: Avoid unnecessary logs by better adjusting the tls_sender
    process to the new supervisor structure in OTP-24.2
  * erts: Fixed a memory leak in file:read_file_info/2 and
    file:read_file/1 on Windows.
  * erts: Fix GC emulator crash when spawn_request was used when
    message tracing was enabled.
