- 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.
