---------------------------------------------------------------------
--- HIGHLIGHTS ------------------------------------------------------
---------------------------------------------------------------------
OTP-13872 Application(s): crypto
The Message Authentication Codes (MAC) CMAC, HMAC and
Poly1305 are unified into common functions in the New
Crypto API. See the manual for CRYPTO.
OTP-15431 Application(s): ssl
Basic support for TLS 1.3 Client for experimental use.
For more information see the Standards Compliance
chapter of the User's Guide.
OTP-15738 Application(s): erts
Related Id(s): PR-2361
erlc can now automatically use a compile server to
avoid starting an Erlang system for each file to be
compiled in a multi-file project. See the documentation
for how to enable it.
---------------------------------------------------------------------
--- POTENTIAL INCOMPATIBILITIES -------------------------------------
---------------------------------------------------------------------
OTP-15510 Application(s): stdlib
Debugging of time-outs in gen_statem has been improved.
Starting a time-out is now logged in sys:log and
sys:trace. Running time-outs are visible in server
crash logs, and with sys:get_status. Due to this system
events {start_timer, Action, State} and {insert_timout,
Event, State} have been added, which may surprise tools
that rely on the format of these events.
New features: The EventContent of a running time-out
can be updated with {TimeoutType, update,
NewEventContent}. Running time-outs can be cancelled
with {TimeoutType, cancel} which is more readable than
using Time = infinity.
OTP-15979 Application(s): mnesia
Related Id(s): ERL-768
Transactions with sticky locks could with async_asym
transactions be committed in the wrong order, since
asym transaction are spawned on the remote nodes.
To fix this bug the communication protocol between
mnesia nodes had to be updated, thus mnesia will no
longer be able to connect to nodes earlier than
mnesia-4.14 , OTP-19.0.
---------------------------------------------------------------------
--- OTP-22.1 --------------------------------------------------------
---------------------------------------------------------------------
--- Improvements and New Features ---
OTP-16051 Application(s): erl_docgen, otp
Update the documentation build support to handle FOP
2.1 .
---------------------------------------------------------------------
--- common_test-1.18 ------------------------------------------------
---------------------------------------------------------------------
The common_test-1.18 application can be applied independently of
other applications on a full OTP 22 installation.
--- Fixed Bugs and Malfunctions ---
OTP-15863 Application(s): common_test
Related Id(s): ERIERL-370
If a ct hook is installed in the suite/0 function in a
test suite, then the hook's terminate/1 function would
be called several times without it's init/2 function
being called first. This is now corrected.
OTP-15869 Application(s): common_test
Related Id(s): ERIERL-350
If init_per_testcase fails, the test itself is skipped.
According to the documentation, it should be possible
to change the result to failed in a hook function. The
only available hook function in this case is
post_init_per_testcase, but changing the return value
there did not affect the test case result. This is now
corrected.
--- Improvements and New Features ---
OTP-15789 Application(s): common_test
Add ct_netconfc support for NETCONF 1.1 (RFC 6241). The
1.1 base capability can be sent in hello, and RFC 6242
chunk framing is applied when both client and server
advertise 1.1 support.
OTP-15934 Application(s): common_test
Correct lib_dir paths in common_tests opaque data
structure that is passed to ct_release_test callback
modules in functions upgrade_init/2, upgrade_upgraded/2
and upgrade_downgraded/2. The incorrect paths may cause
confusion when debugging although it will not cause any
incorrect behavior on the part of common_test as it is
currently not used.

--- compiler-7.4.5 --------------------------------------------------
---------------------------------------------------------------------
The compiler-7.4.5 application can be applied independently of other
applications on a full OTP 22 installation.
--- Fixed Bugs and Malfunctions ---
OTP-15833 Application(s): compiler
Code such as the following would crash the compiler in
OTP 22: [some_atom = fun some_function/1]
OTP-15923 Application(s): compiler
Compilation could get really slow (in the order of
minutes instead of seconds) when compiling huge
functions. (Thanks to Kostis Sagonas for reporting this
bug.)
OTP-15954 Application(s): compiler
Related Id(s): ERL-995
Fixed a bug in the validator that could reject valid
code.
OTP-15963 Application(s): compiler
In rare circumstances, when two clauses had identical
bodies and guard tests that tested a single boolean
variable, the guard test for the second clause could be
discarded, executing the second clause unconditionally
if the first clause was not executed.
OTP-15966 Application(s): compiler
Related Id(s): ERL-1014
Fixed extremely slow compilation for huge functions
doing predominantly pattern matching.
OTP-15968 Application(s): compiler
Related Id(s): ERL-1017
The compiler could generate unsafe code (that would
crash the runtime system) for map pattern matching. The
code could be unsafe if the matched key was not present
in the map at runtime.
OTP-15969 Application(s): compiler
Related Id(s): ERL-997
Correct code using try/after could fail to compile when
using the option 'no_type_opt'.
OTP-15970 Application(s): compiler
Related Id(s): ERL-1013
The compiler could crash when compiling code that
called 'length/1' on a binary extracted using the
binary syntax.
OTP-15982 Application(s): compiler
Related Id(s): ERL-1022
Fixed a bug where the compiler could fail with an
internal consistency failure error when compiling
receive statements.
OTP-15985 Application(s): compiler

OTP-15884 Application(s): crypto
Related Id(s): ERL-974
The implementation of crypto_one_time/4 is adjusted to
match the type specification. The spec and the
black-box behaviour of the function are unchanged.
Some details: Both the spec and the implementation were
correct seen separately. But with both of them combined
simultaneously with crypto_one_time/5 which was called
by the implementation of crypto_one_time/4, an
(obvious) error was detected by a Dialyzer with more
thorough checking than usual.
OTP-15911 Application(s): crypto
When using crypto with FIPS mode enabled, the digests
were not correctly handled.
OTP-15924 Application(s): crypto
A memory leak in error handling code in
ng_crypto_init_nif is fixed.

OTP-15370 Application(s): erts
Related Id(s): ERIERL-353
If you set {linger,{true,0}} on a gen_tcp listen
socket, accept a connection on that socket, and then
close the accepted socket, now the linger zero setting
is transferred to the accepted socket. Before this
correction that information was lost and the close
behaviour on the accepted socket incorrect.
OTP-15422 Application(s): erts
Related Id(s): OTP-15747
Sending ancillary data implemented in OTP-15747
accidentally left behind test code that caused all UDP
sends to fail on Windows. This has now been fixed.

OTP-15849 Application(s): erts
Related Id(s): ERL-700
Fixed bug in seq_trace:set_token(label,Term) which
could cause VM crash if Term was heap allocated (not an
atom, small integer, local pid or port). Bug exists
since OTP 21.0 when terms other than small integers
were first allowed as labels.

Fixed hipe_flush_icache_range for non-Linux OS on ARM.
OTP-15881 Application(s): erts
The fix in OTP-15871 was too conservative and disabled
the offending load-time optimization in some cases
where it was safe.
OTP-15889 Application(s): erts, stdlib
Upgraded the ERTS internal PCRE library from version
8.42 to version 8.43. See

Allow more than one -config command line option to erl
on Windows to conform with other OS.
OTP-15931 Application(s): erts
Fix so that ERL_FLAGS environment variable does not
interfere with command line arguments. Before this fix
you could write:
ERL_FLAGS="10" erl +S
and erlang would start as if +S had been given the
argument 10.
OTP-15959 Application(s): erts, stdlib
Related Id(s): ERL-717
The bug with ID ERL-717 has been fixed. The functions
io:columns() and io:rows() only worked correctly inside
interactive erlang shells before this fix. These
functions returned {error,enotsup} before this fix even
if stdout and stdin were connected to a terminal when
they were invoked from an escript or a program started
with e.g., erl -noshell.
OTP-15971 Application(s): erts

process_info(P,binary) would neglect to look through
heap fragments, potentially missing a few binaries
associated with the process.
OTP-16037 Application(s): erts
HiPE is now automatically disabled on systems with
non-glibc implementation (for instance musl). This is
because musl does not provide the API's for

If the log file was given with relative path, the
standard logger handler (logger_std_h) would store the

ssh:daemon/2 the function ssh:daemon_info/1 returning
all information was available. This ticket adds
ssh:daemon_info/2 which returns only the information
specified in the second argument.

includes the item 'options'. Only those options that
does not have their default values are returned.
For a connection also the items 'algorithms' and

Debugging of time-outs in gen_statem has been improved.
Starting a time-out is now logged in sys:log and
sys:trace. Running time-outs are visible in server
crash logs, and with sys:get_status. Due to this system
events {start_timer, Action, State} and {insert_timout,
Event, State} have been added, which may surprise tools
that rely on the format of these events.
New features: The EventContent of a running time-out
can be updated with {TimeoutType, update,
NewEventContent}. Running time-outs can be cancelled
with {TimeoutType, cancel} which is more readable than
using Time = infinity.
