--- HIGHLIGHTS ------------------------------------------------------
---------------------------------------------------------------------
OTP-15856 Application(s): ssl
Implementation of the key and initialization vector
update feature, and general hardening of TLS 1.3.
There are cryptographic limits on the amount of
plaintext which can be safely encrypted under a given
set of keys.
This change enforces those limits by triggering
automatic key updates on TLS 1.3 connections.
OTP-16253 Application(s): ssl
Add support for TLS 1.3 Session Tickets (stateful and
stateless). This allows session resumption using keying
material from a previous successful handshake.
OTP-16309 Application(s): erts, sasl
A socket "registry" has been added making it possible
to list current open sockets.
OTP-16485 Application(s): ssh
The new functions ssh:set_sock_opts/2 and
ssh:get_sock_opts/2 sets and reads option values for
the underlying TCP stream.

when built with gcc option -fno-common. Error exists
since OTP-21.3.
---------------------------------------------------------------------
--- erts-10.7 -------------------------------------------------------

-- kernel-6.5.1 (first satisfied in OTP 22.2)
--- Fixed Bugs and Malfunctions ---
OTP-16059 Application(s): erts
gen_udp:recv(S, N, 0) corrupted the internal state for
the socket so after receive with {active, once} it
always returned {error, timeout}, and wasted the
received UDP packets. This bug has now been fixed.
Reported and pinpointed by Alexander Petrovsky.
OTP-16381 Application(s): erts
The atom esock_atom_user and esock_atom_kernel was
never actually created. This has now been corrected.
OTP-16384 Application(s): erts
Fixed bug in socket module that could potentially lead
to scheduler deadlocks.
OTP-16399 Application(s): erts
Fix bug causing VM crash if down or stop callback of a
NIF resource is called after the NIF module has been
purged. The fix will postpone unloading until all such
resource objects have been garbage collected.
OTP-16404 Application(s): erts
Related Id(s): ERL-1127
Fixed bug in ets:update_counter/4, when called with an
invalid UpdateOp and a Key that does not exist, causing
ets:info(T,size) to return incorrect values. Bug exists
since OTP-19.0.2.
OTP-16417 Application(s): erts
Fix potential heap corrupting bugs when a process calls
a BIF that blocks other normal schedulers and then
writes to its own heap without the main process lock. A
NIF running on a dirty scheduler trying to interact
with such a process could corrupt its heap. The fixed
BIFs were related to code loading and tracing.
OTP-16438 Application(s): erts
Fixed bug in erlang:list_to_ref/1 when called with a
reference created by a remote note. Function
list_to_ref/1 is intended for debugging and not to be
used in application programs. Bug exist since OTP 20.0.
OTP-16440 Application(s): erts, kernel
The prim_net nif (net/kernel) made use of an undefined
atom, notsup. This has now been corrected.
OTP-16481 Application(s): erts
Corrected the valid range of the erl command line
argument +SDio <NumberOfDirtyIoSchedulers> from 0..1024
to 1..1024. +SDio 0 was erroneously allowed which just
caused the VM to crash on the first dirty I/O job
scheduled.
OTP-16491 Application(s): erts, kernel
Fix a crash when attempting to log faults when loading
files during early boot.
--- Improvements and New Features ---
OTP-16153 Application(s): erts
For socket, not all send and receive flags are
supported on all platforms. In order to (at least)
simplify testing, the socket:supports/0,1,2,3 functions
has been extended with send_flags and recv_flags items,
which indicates what the current platform can manage.
OTP-16212 Application(s): erts

module.
OTP-16306 Application(s): erts
Related Id(s): ERIERL-439

been added to the BIF erlang:open_port/2. The
busy_limits_port option can be used for controlling the
busy state of a port executing the spawn_driver or the
fd_driver. The busy_limits_msgq option can be used for
controlling the busy state of the port message queue.
OTP-16309 Application(s): erts, sasl
*** HIGHLIGHT ***
A socket "registry" has been added making it possible
to list current open sockets.
OTP-16387 Application(s): erts
The counters managed by the socket nif has been
extended. Their "size" has been increased from 32 bit
to 64. Two max package size (for read and write) has
been added. And four accept counters has been added.
OTP-16420 Application(s): erts
Related Id(s): PR-2513
Add gcc option -fno-common to detect accidental name
clashes of global variables.
OTP-16427 Application(s): erts
New dynamic lock checker that verifies locking orders

NIFs. Enabled together with the old static lock checker
(for ERTS internal locks) in emulator started with
-emu_type debug or built with configuration option
--enable-lock-checking.
