--- Fixed Bugs and Malfunctions ---
OTP-17628 Application(s): erts
A call to process_info(Pid, status) could erroneously
report the status running when it should have reported
waiting. This occurred when the calling process was
executing on a higher priority than the process being
inspected. This bug has been present since OTP 21.0
(erts version 10.0).
OTP-17642 Application(s): erts
Related Id(s): PR-5248
A race between an exiting port and handling of
simultaneously received signals to that port could
cause a runtime system crash. The effected signals are
link, monitor and demonitor. On OTP 22 a similiar race
could also cause a memory leak when receiving an unlink
signal.
OTP-17651 Application(s): erts
Related Id(s): GH-5235, PR-5244
The message queue of a process entered an inconsistent
state after a receive expression with an invalid
timeout value was executed. If the exception raised due
to the invalid timeout value was caught, the following
receive expression executed by the process could fail
to match messages already present in the message queue.
On OTP 24 this could also cause the whole runtime
system to crash.
OTP-17665 Application(s): erts
Related Id(s): PR-5248
Sending a Port ! {PortOwner, close} signal from a
process other than the port owner could erroneously
trigger a badsig exit signal being sent to the port
owner process even though the correct PortOwner had
been passed in the signal.
OTP-17677 Application(s): erts
This fixes a bug in erts_factory_undo that caused the
heap to not be reset correctly. The erts_factory_undo
function is, for example, called when a
binary_to_term/1 call fails to reset the heap to its
state before the binary_to_term/1 call. This can cause
the heap to contain invalid terms which potentially can
cause issues (e.g., crashes) when the whole heap is
scanned.
OTP-17700 Application(s): erts
Related Id(s): GH-5271, PR-5273
Fix bug in persistent_term when a key-value pair
contains a magic reference that is referred more than
once. Magic references are NIF resources or returned
from BIFs like ets:new, atomics:new. The bug could
cause the memory of the referred resource to be
prematurely deallocated.
The bug also apply to magic references in message
passing on a runtime built with configure option
--enable-sharing-preserving.
Bug exist for 64-bit since OTP-24.0 and for 32-bit
since OTP-20.0.
--- Improvements and New Features ---
OTP-17658 Application(s): erts
The python scripts that existed in
erts/lib_src/yielding_c_fun/lib/tiny_regex_c/scripts
had a license that was incompatible with Erlang/OTP's
license. This ticket removes these scripts that were
not used by us.

The ssh-4.11.1.4 application can be applied independently of other
applications on a full OTP 23 installation.

OTP-17707 Application(s): ssh
Related Id(s): ERIERL-706
The value of the connect_timeout option is now used as
default value for the negotiation timeout.
